Two new papers will be presented at The Sixth IASTED International Conference on Signal Processing, Pattern Recognition and Applications ~SPPRA 2009~.
In the first paper we present a new low level compact composite descriptor for Content Based Medical Image Retrieval.
Abstract: The rapid advances made in the field of radiology, the increased frequency in which oncological diseases appear, as well as the demand for prevailing medical checks, led to the creation of a large database of radiology images in every hospital or medical center. There is now an imperative need to create an effective method for the indexing and retrieval of these images. This paper proposes a new method for content based medical image retrieval. The description of images relies on a new Composite Descriptor (CD) which includes global image features, capturing both brightness and texture characteristics at the same time. Image information is extracted using a set of fuzzy approaches. To be applicable in the design of large medical image databases, the proposed descriptor is compact, requiring only 48 bytes per image. Experiments demonstrate the effectiveness of the proposed technique. Authors: Savvas A. Chatzichristofis and Yiannis Boutalis.
The second paper is presenting a method for auto selection the proper compact composite descriptor in order to retrieve natural color images.
Abstract: Compact Composite Descriptors (CCD) are global image features capturing both, color and texture characteristics, at the same time in a very compact representation. In this paper we propose a combination of two recently introduced CCDs (CEDD and FCTH) into a Joint Composite Descriptor (JCD). We further present a method for descriptor selection to approach the best ANMRR that would result from CEDD and FCTH. With our approach the most appropriate descriptor in terms of maximization of information content can be found on a per image basis without knowledge of the data set as a whole. Experiments conducted on three known benchmarking image databases demonstrate the effectiveness of the proposed technique. Authors: Savvas A. Chatzichristofis, Mathias Lux and Yiannis Boutalis.
The descriptors will be added soon in the CCD section.

Video summary generation. A java based open source project
Mathias Lux is working on a summary tool, which extracts still images from a video. The goal of the tool is to find frames, which describe the image in an optimal way. Now it’s in a (rather) stable state and ready to release. For Windows users it should be a single click to start the thing, for Linux you need to install ffmpeg. Note that the tool is open source & the code is GPL-ed

New search-by-style options for Google Image Search
Many of us use Google Image Search to find imagery of people, clip art for presentations, diagrams for reports, and of course symbols and patterns for artistic inspiration. Unfortunately, searching for the perfect image can be challenging if the search results match the meaning of your query but aren't in a style that's useful to you. So some time ago we launched face search, which lets you limit your search results to only images containing faces (see a search without and with this option). More recently we also rolled out photo search, which limits results to images that contain photographic elements, ignoring many cartoons and drawings which may not be useful to you (see a search without and with this option).Today we're pleased to extend this capability to clip art and line drawings. To see the effect of these new options, let's take a look at the first few results for "Christmas," one of our most popular queries on Image Search right now.
All of these options can be selected from the "Any content" drop down in the blue title bar on any search results page, or by selecting one of the "Content types" on the Advanced Image Search page. The good news: no extra typing! In all these examples our query remained exactly the same, we just restricted our results to different visual styles. So whether you're interested holiday wreaths, Celtic patterns, or office clip art, it just became a lot easier to find the images you're looking for.

Things You Need to Know Before You Buy Digital Camera
Digital cameras come in many sizes, colors, brands, zooms, resolutions, playbacks, etc. There are so many features and qualities that are being placed in the devices that buyers especially first timers become overwhelmed and dizzy with these outstanding arrays of gadgets. This is even without including the various advertisements and different ratings that are used to promote these products.
So what are the things to look for if you want to buy digital camera? To be able to answer these, there are 2 sets of information you have to know before you can decide. The first type of information is defining what YOU need and want in a digital camera. To do this, you can ask yourself the following questions:
What do you want to take with your digital camera? Before you buy digital camera, it is important to determine what kind of pictures you want to take with it. If you are a digital photography enthusiast, any digital camera will not just do. You have to look for features that can support the zooming you need, the resolution, etc.
How much is your budget? This is a very important question any person who intends to buy digital camera should ask. Because no matter what your needs and wants are for the device, your financial resource will play a huge part in dictating the type of digital camera you will buy.
What are you resources? When you buy digital camera, sometimes the spending does not end there. You also have to consider the capacity and the power of the computer and the printer you will be hooking your camera with for your editing and printing needs. Editing software are already included when you buy digital camera but other devices aren’t. Aside from a printer, ink and paper for printing, you might also need additional memory cards for your camera and a more powerful computer to support image editing and image storage and retrieval.

Benchmark databases for CBIR
Recently, standard benchmark databases and evaluation campaigns have been created allowing a quantitative comparison of CBIR systems. These benchmarks allow the comparison of image retrieval systems under different aspects: usability and user interfaces, combination with text retrieval, or overall performance of a system.
1. WANG database
The WANG database is a subset of 1,000 images of the Corel stock photo database which have been manually selected and which form 10 classes of 100 images each. The WANG database can be considered similar to common stock photo retrieval tasks with several images from each category and a potential user having an image from a particular category and looking for similar images which have e.g. cheaper royalties or which have not been used by other media. The 10 classes are used for relevance estimation: given a query image, it is assumed that the user is searching for images from the same class, and therefore the remaining 99 images from the same class are considered relevant and the images from all other classes are considered irrelevant
2. The MIRFLICKR-25000 Image Collection
The new MIRFLICKR-25000 collection consists of 25000 images downloaded from the social photography site Flickr through its public API.
Features:
- OPEN
Access to the collection is simple and reliable, with image copyright clearly established. This is realized by selecting only images offered under the Creative Commons license. See the copyright section below. - INTERESTING
Images are also selected based on their high interestingness rating. As a result the image collection is representative for the domain of original and high-quality photography. - PRACTICAL
In particular for the research community dedicated to improving image retrieval. We have collected the user-supplied image Flickr tags as well as the EXIF metadata and make it available in easy-to-access text files. Additionally we provide manual image annotations on the entire collection suitable for a variety of benchmarks.
MIRFLICKR-25000 is an evolving effort with many ideas for extension. So far the image collection, metadata and annotations can be downloaded below. If you enter your email address before downloading, we will keep you posted of the latest updates.
3. UW database
The database created at the University of Washington consists of a roughly categorized collection of 1,109 images.These images are partly annotated using keywords. The remaining images were annotated by our group to allow the annotation to be used for relevance estimation; our annotations are publicly available10.The images are of various sizes and mainly include vacation pictures from various locations. There are 18 categories,for example “spring flowers”, “Barcelona”, and “Iran”. Some example images with annotations are shown in Figure 2. The complete annotation consists of 6,383 words with a vocabulary of 352 unique words. On the average, each image has about 6 words of annotation. The maximum number of key-words per image is 22 and the minimum is 1. The database is freely available11. The relevance assessment for the experiments with this database were performed using the annotation: an image is considered to be relevant w.r.t. a given query image if the two images have a common keyword in the annotation. On the average, 59.3 relevant images correspond to each image. The keywords are rather general; thus for example images showing sky are relevant w.r.t. each other,which makes it quite easy to find relevant images (high precision is likely easy) but it can be extremely difficult to obtain a high recall since some images showing sky might have hardly any visual similarity with a given query.This task can be considered a personal photo retrieval task,e.g. a user with a collection of personal vacation pictures is looking for images from the same vacation, or showing the same type of building.
4. IRMA-10000 database
The IRMA database consists of 10,000 fully annotated radio-graphs taken randomly from medical routine at the RWTH Aachen University Hospital. The images are split into 9,000training and 1,000 test images. The images are sub dividedinto 57 classes. The IRMA database was used in the ImageCLEF 2005 image retrieval evaluation for the automatic annotation task. For CBIR, the relevances are defined by the classes, given a query image from a certain class, all database images from the same class are considered relevant

5. ZuBuD database
The “Zurich Buildings Database for Image Based Recognition”(ZuBuD) is a database which has been created by the Swiss Federal Institute of Technology in Zurich. The database consists of two parts, a training part of 1,005images of 201 buildings, 5 of each building and a query part of 115 images. Each of the query images contains one of the buildings from the main part of the database. The pictures of each building are taken from different viewpoints and some of them are also taken under different weather conditions and with two different cameras. Given a query image, only images showing exactly the same building are considered relevant.

6. UCID database (Suggested)
The UCID database13 was created as a benchmark database for CBIR and image compression applications. This database is similar to the UW database as it consists of vacation images and thus poses a similar task.For 264 images, manual relevance assessments among all database images were created, allowing for performance evaluation. The images that are judged to be relevant are images which are very clearly relevant, e.g. for an image showing a particular person, images showing the same person are searched and for an image showing a football game, images showing football games are considered to be relevant. The used relevance assumption makes the task easy on one hand,because relevant images are very likely quite similar, but on the other hand, it makes the task difficult, because there are likely images in the database which have a high visual similarity but which are not considered relevant. Thus, it can be difficult to have high precision results using the given rel-evance assessment, but since only few images are considered relevant, high recall values might be rather easy to obtain.

7.Yaroslav Bulatov OCR dataset
<Yaroslav Bulatov> I've collected this dataset for a project that involves automatically reading bibs in pictures of marathons and other races. This dataset is larger than robust-reading dataset of ICDAR 2003 competition with about 20k digits and more uniform because it's digits-only. I believe it is more challenging than the MNIST digit recognition dataset.
I'm now making it publicly available in hopes of stimulating progress on the task of robust OCR. Use it freely, with only requirement that if you are able to exceed 80% accuracy, you have to let me know ;)
The dataset file contains raw data (images), as well as Weka-format ARFF file for simple set of features.
For completeness I include matlab script used to for initial pre-processing and feature extraction, Python script to convert space-separated output into ARFF format. Check "readme.txt" for more details.

Imprezzeo
Imprezzeo, backed by Independent News and Media PLC launches its new image search product providing a new way of searching for digital images. The beta product uses images to search for images, rather than text.
Press Release:
Images can be scenes; landmarks; objects; graphics; people or even personalities. Irrespective of the size of the image collection Imprezzeo Image Search helps users find the right image - fast. For a demonstration, visit www.imprezzeo.com.
The potential for this technology is huge. Stock photo libraries and news agencies can provide more relevant search results to image buyers (and sell content that might not have been found using traditional text-based search); search engines can provide users with a far more sophisticated image search experience than is currently available; photo sharing sites can offer search by example image, rather than search that solely relies on user’s tagging; consumers can organise their personal photo collections by content and person rather than by date; even retailers can recommend similar products for purchase (for example, if a consumer is searching for a ‘red handbag’, Imprezzeo could be used to find all similar products).
The proprietary search software is more sophisticated than any other image-based search technology on the market, combining content-based image retrieval (CBIR) and facial recognition technologies. Imprezzeo’s sophisticated image analytics ensures the Imprezzeo platform can deliver great results when applied to a whole range of different image content and when used in a whole range of applications.
The new technology generates image search results that closely match a sample image either chosen by the user from an initial set of search results that can then be refined, or from an image uploaded by the user.
Dermot Corrigan, CEO of Imprezzeo, says: “This will fundamentally change the way users and consumers expect to search for images, whether that’s in a photo stock library, the desktop or the web. We know that currently many image searches are abandoned at the first set of results, because the returned results are not what the user is looking for. This technology changes that.”

ImageSorter V3 (Beta 3)
ImageSorter is an image browsing application, which allows an automatic sorting by color, date taken, name, or size.
The idea of ImageSorter is to find images of which you remember how they look but you forgot in which folder they were. If one or several folders are selected, all images from these folders will be visually arranged such that similar images are close to each other. In this sorted display it will be much easier to find a particular image. Selected images can be copied, moved or deleted (right mouse click).ImageSorter does cache thumbnails and sortings, therefore after images have been loaded once, everything will be much faster.
The current version of ImageSorter is 3.0 BETA 3 for Windows and V2.0.2 for Mac OS X. ImageSorter 3 introduced an Internet image search (Yahoo! and Flickr) and the possibility to search for similar images on the local disk or the Internet. The software profits from a greatly improved stability and run-time performance. Furthermore quite a few suggestions made in the forum have been included. See the change log for a detailed list of changes

pixolu
pixolu is a prototype of an image search system combining keyword search with visual similarity search and semi-automatically learned inter-image relationships. Enter a search term and pixolu searches the image indexes of Yahoo and Flickr. Compared to other image search systems pixolu retrieves more images in an initial phase. Due to a visually sorted display up to several hundred images can be easily inspected, which in most cases is sufficient to get good representations of the entire result set. The user can quickly identify images, which are good candidates for his/her desired search result.In the next step the selected candidate images are used to refine the result by filtering out visually non-similar images from an even larger result set. In addition pixolu learns the inter-image relationships from the candidate sets of different users. This helps pixolu to suggest other images that are semantically similar to the candidate images.

Yahoo's New VideoTagGame Lets You Tag Within Videos
The transfer of human intelligence to the machine is something the internet makes easy to do. With reCAPTCHA, we keep spammers at bay while helping digitize old books, Amazon's Mechanical Turk lets us crowdsource small tasks to a dynamic human workforce available on demand, and Google Image Labeler makes the tedious task of tagging fun. Now Yahoo is trying to tap into that human machine through their new VideoTagGame, a game that encourages participants to tag sections within a video for better retrieval.
The first VideoTagGame ran back in summer of 2007 during a Yahoo! party in Amsterdam. Now they're ready to take their experiment to the public through the Yahoo! Sandbox so they can collect more statistics on its usage.
The objective of the VideoTagGame is to collect time-based annotations of the video which could then enable the retrieval of relevant parts in a video when a search is performed, rather than returning the entire video itself. These annotations are collected in the context of a multi-player game.
How To Play
To play the VideoTagGame, participants must sign in with their Yahoo! ID and join a new game. There will always be at least three players in each game. After a 3-second countdown, the video will begin to play. As it plays, participants enter tags that correspond to the various parts of the video. When two players agree on a tag (that is, they enter the same tag), they each get points. The closer together the tags were entered, the more points are rewarded. After the video ends, participants can then watch as it plays again, this time with the tags overlaid on top of the video.

Yottalook
Yottalook™ is a free radiology-centric web search engine the provides desicion support at the point of care using proprietary relevance and ranking algorithms by iVirtuoso. Yottalook™ is designed to provide the practicing radiologists the most important and most relevant information they need at the time of patient care.
Core Technologies
Core Technologies
Yottalook™ is based on core technologies developed by iVirtuoso to achieve optimized search results. First is automated analysis of the search term to understand what the radiolgist is trying to look for - this core technology is called "natural query analysis".
Yottalook™ has also developed a thesaurus of medical terminologies that not only identifies synonyms of terms but also defines relationships between terms. This second core technology is called "semantic ontology" and is based on existing medical ontologies that have been enhanced by iVirtuoso, such as RadLex - A Lexicon for Uniform Indexing and Retrieval of Radiology Information Resources developed by the Radiology Society of North America.
Third core technology is "relevance algorithm" for image search that differentiates medical terms from other words in text associated with medical images and uses them to create ranking for Yottalook image search.
The fourth core technology is a specialized content delivery system called "Yottalinks" that provides high yield content based on the search term. This content may also be provided by a third party vendor licensing Yottalook search. Yottalook™ can be integrated with any web based medical application so that context relevant information is provided to the physician at the point of care. http://www.yottalook.com/

Pen with digital capabilities is a truly innovative and fun way to take notes and record audio
Livescribe's Pulse "smartpen" is part pen, part voice recorder, and part nothing you've ever seen before. Remember Picture Pages? If not, watch this YouTube clip, and then imagine Livescribe's Pulse as the Picture Pages pen on a combination of steroids, hallucinogens, and time-travel pills. It's fun to use, and it could prove to be a groundbreaking, useful tool for students, meeting-hoppers, and journalists.

Kitware
Kitware, a software company with offices in New York and North Carolina, won an initial $6.7 million contract for what is technically called Video and Image Retrieval and Analysis Tool, or VIRAT.In a statement about the contract award, Kitware projected that through its proposed system, “the most high-value intelligence content will be clearly and intuitively presented to the video analyst, resulting in substantial reductions in analyst workload per mission as well as increasing the quality and accuracy of intelligence yield.”Anthony Hoogs, Kitware’s project leader, said, ”This project will really make a difference to the war fighter.”To carry out the project, Kitware said it was teaming up with two leading military technology companies, Honeywell and General Dynamics, as well as a number of academic researchers.

ACM CIVR 2009
ACM International Conference on Image and Video Retrieval
July 8-10, 2009, Santorini Island, Greece - http://www.civr2009.org/ -
Image and Video retrieval have now reached a state where successful techniques and applications start flourishing. The ACM International Conference on Image and Video Retrieval (ACM-CIVR) series of conferences is the ideal opportunity to present and encounter such developments. Originally set up to illuminate the state-of-the-art in image and video retrieval throughout the world, it is now a reference event in the field where researchers and practitioner exchange knowledge and ideas. CIVR2009 is seeking original high quality special sessions addressing innovative research in the broad field of image and video retrieval. We wish to highlight significant and emerging areas of the main problem of search and retrieval but also the equally important related issues of multimedia content management, user interaction and community-based management.
Example topics of interest include but are not limited to: social network information mining, unsupervised methods for data exploration, large scale issues for algorithms and data set generation.
Each special session will consist of 5 invited papers. The organizers’ role is to attract the speakers and chair the session itself. Proposals will be evaluated based on the timeliness of the topic, relevance to CIVR, the degrees to which they will bring together key researchers in the area, introduce the area to the larger research community, further develop the area, and potentials to establish a larger community around the area. Please note that all papers in the proposed session will undergo the same review process as regular papers. If after the reviewing process less than the necessary number of papers solicited for a special session are selected, the Special Session will be cancelled, and the solicited papers that passed review process will be presented within regular sessions of the conference.

Photo Tourism: Exploring Photo Collections in 3D
Photo Tourism is a system for browsing large collections of photographs in 3D. Our approach takes as input large collections of images from either personal photo collections or Internet photo sharing sites, and automatically computes each photo's viewpoint and a sparse 3D model of the scene. Our photo explorer interface enables the viewer to interactively move about the 3D space by seamlessly transitioning between photographs, based on user control.
Microsoft Live Labs has turned these research ideas into a streaming multi-resolution Web-based service called Photosynth.
You can also read about newer research we have been doing in this area at the University of Washington Photo Tourism project page.

Noah Snavely, Steven M. Seitz, and Richard Szeliski, Photo Tourism: Exploring photo collections in 3D," ACM Transactions on Graphics, 25(3), August 2006. (Video WMV), Video (MOV))Abstract
We have developed a system for interactively browsing and exploring large unstructured collections of photographs of a scene using a novel 3D interface. Our system consists of an image-based modeling front end, which automatically computes the viewpoint of each photograph as well as a sparse 3D model of the scene and image to model correspondences. Our photo navigation tool uses image-based rendering techniques to smoothly transition between photographs, while also enabling full 3D navigation and exploration of the set of images and world geometry, along with auxiliary information such as overhead maps. Our system also makes it easy to construct photo tours of scenic or historic locations, as well as to annotate image details, which are automatically transferred to other relevant images in the collection. We demonstrate our system on several large personal photo collections as well as images gathered from photo sharing Web sites on the Internet.

EngLab - Open Source Mathematical Platform
EngLab is a cross-compile mathematical platform with a C like syntax, intended to be used both by engineers and users with little programming knowledge. The initiative has been taken from a group of students a year ago.
"Our goal is to develop an easy-to-use computaion and simulation platform with a C++ like syntax. We have adopted Matlab's structure philoshophy and C++ 's structured language syntax. There are various toolboxes (packages of functions relative to a certain scientific field), which depend on open-source libraries." EngLab Team
The EngLab distribution is available in two ways: there are two basic Englab releases, EngLab Console and EngLab GUI. EngLab Console allows EngLab's execution through the console(Linux or Windows). EngLab GUI gives the opportunity of using EngLab through a graphical user interface. EngLab GUI is implemented with the use of the open-source library wxWidgets 2.8, providing additional usability compared to EngLab Console edition. EngLab GUI is independent, so there is no need for EngLab Console to be installed, in order to properly install and execute EngLab GUI.
Toolboxes are distributed as seperate packages. Their installation is possible either through EngLab Console or EngLab GUI. The reason is that those toolboxes depend on open-source libraries that have to be previously installed. So as the user not to be forced to install those libraries directly, user can install packages and toolboxes at his/her own will.
For the time being, EngLab Console edition is available for Windows and Linux and Englab GUI is available for Linux only.
Until now EngLab has the following features :
- 16 types of variable declaration (int, float, ...)
- Variable declaration with unlimited number of dimensions.
- Loop structures (for, while, ...)
- Arithmetic, logical and binary operations
- Constant number declaration (pi, phi, ...)
- Graphical manipulation of variable values of any dimension (Englab GUI)
- Adjustable graphical environment (Englab GUI)
- Editor for writing *.eng functions (Englab GUI)
- Command history for the last 5 sessions
- Immediate access to variables, constants and functions (EngLab GUI)
- Recent files opened through EngLab (EngLab GUI)
Toolboxes that have been fully or partially implemented:
- a package containing fundamental functions of C (trigonemetric, hyperbolic trigonometrical, ...)
- a package containing some statistic functions
- a package containing functions that allow convertions of the variable type
All these toolboxes accompany the basic two EngLab editions, since they do not depend on another open-source library. Moreover, some other toolboxes have been partially implemented:
- a package that contains functions for the manipulation of 2-D matrices (determinant, inverse array, ...). This package depends on the open-source library NewMat10.
- a package that contains functions for image processing. This package depends on the open-source library CImg.
- a package that contains functions for image processing. This package depends on the open-source library OpenCV.
- a toolbox for visual data representation(plots etc)
- a toolbox that contains functins for manipulating polyonymials, root detection, computation of integrals and derivatives, special functions and more.

Smile And Robot Smiles With You
Humanoid 'Jules' is a disembodied androgynous robotic head that automatically copies the movement and expressions of a human face.
The technology works using 10 stock human emotions - for instance happiness, sadness, concern - that have been programmed into the robot.
The software then maps what it sees to Jules' face to combine expressions instantly to mimic those being shown by a human subject.
Controlled only by its own software, Jules can grin and grimace, furrow its brow, and 'speak' as the software translates real expressions observed through video camera 'eyes'.
If you want people to be able to interact with machines, then you've got to be able to do it naturally...When it moves it has to look natural in the same way that human expressions are, to make interaction useful.Chris Melhuish, head of the Bristol Robotics Laboratory
The robot - made by US roboticist David Hanson - then copies the facial expressions of the human by converting the video image into digital commands that make the robot's inner workings produce mirrored movements.
And it all happens in real time as Jules is bright enough to interpret the commands at 25 frames per second.
The project was developed over more than three years at the Bristol Robotics Laboratory, a lab run by the University of the West of England and the University of Bristol under the leadership of Chris Melhuish, Neill Campbell and Peter Jaeckel.
The aim of the developers was to make it easier for humans to interact with 'artificial intelligence', in other words to create a 'feelgood' factor.
The BRL's Peter Jaeckel said: ''Realistic, life-like robot appearance is crucial for sophisticated face-to-face robot - human interaction.
''Researchers predict that one day robotic companions will work, or assist humans in space, care and education. Robot appearance and behaviour need to be well matched to meet expectations formed by our social experience."
But a warning note has been sounded.
Kerstin Dautenhahn, a robotics researcher at the University of Herefordshire, believes that people may be disconcerted by humanoid automatons that simply look 'too human'.
''People might easily be fooled into thinking that this robot not only looks like a human and behaves like a human, but that it can also feel like a human. And that's not true," she pointed out.

Zunavision: Novel software by Stanford university students/prof to embed video/image inside video
Stanford artificial intelligence researchers have developed software that makes it easy to reach inside an existing video and place a photo on the wall so realistically that it looks like it was there from the beginning. The photo is not pasted on top of the existing video, but embedded in it It works for videos as well - you can play a video on a wall inside your video. The technology can cheaply do some of the tricks normally performed by expensive commercial editing systems.

TouchGraph
TouchGraph lets you see how your friends are connected, and who has the most photos together.
The TouchGraph Facebook Browser shows connections between users based on friendships and common photo appearances.
Friendships are shown as dark gray lines, and common photo appearances are shown as a lighter gray line with a number in the center. The number indicates how many photos the two people appeared in together.
Personal vs. Friends social networks
* When launched from one's own profile, information about all of one's friends and their friendships is loaded.* When launched from another user's profile (Using the "TouchGraph Friends + Photos" link below their profile picture) only people tagged in their photos will appear in the graph.
One can not see another person's whole social network because Facebook only allows applications to get a list of one's own friends. For other users it is only possible to get a list of people that they appear in photos with. Perhaps Facebook's policy will change in the future.
Clusters
The TouchGraph Facebook Browser determines the clusters/cliques to which one's Friends belong and uses different colors to show each clique. Cliques are characterized by having lots of friendships within a group of friends and few connections to members outside the group.
Rank
Friends are assigned a Rank so that one can reduce clutter by only showing a set of 'Top' friends. TouchGraph gives the highest rank to friends who are connectors between different cliques. Finding connecters involves a metric called Betweeness Centrality which is an established measure for a person's importance within a social network.

A New Era for Image Annotation
Searching for images on the Web has traditionally been more complicated than text search – for instance, a Google image search for “tiger” not only yields images of tigers, but also returns images of Tiger Woods, tiger sharks and many others that are ‘related’ to the text in the query string. This is because contemporary search engines look for images using any ‘text’ linked to images rather than the ‘content’ of the picture itself. In an effort to improve the recall of image searches, folks from UC San Diego are working on a search engine that works differently – one that analyzes the image itself. “You might finally find all those unlabeled pictures of your kids playing soccer that are on your computer somewhere,” says Nuno Vasconcelos, a professor of electrical engineering at the UCSD Jacobs School of Engineering. They claim that their Supervised Multiclass Labeling System “may be folded into next-generation image search engines for the Internet; and in the shorter term, could be used to annotate and search commercial and private image collections.

PhotoEnhancer
PhotoEnhancer is an experimental image enhancement software, which employs the characteristics of the ganglion cells of the Human Visual System. Many times the image captured by a camera and the image in our eyes are dramatically different. Especially when there are shadows or highlights in the same scene. In these cases our eyes can distinguish many details in the shadows or the highlights, while the image captured by the camera suffers from loss of visual information in these regions.
PhotoEnhancer attempts to bridge the gap between "what you see" and "what the camera sees". It enhances the shadow or the highlight regions of an image, while keeping intact all the correctly exposed ones. The final result is a lot closer to the human perception of the scene, than the original captured image, revealing visual information that otherwise wouldn't be available to the human observer.
PhotoEnhancer 2.4
The latest version of PhotoEnhancer (2.4) has been released. Version 2.4 features a 'Batch Processing' mode, for the quick enhancement of many image files just with a few clicks, as well as an improved user interface.
Version History:
PhotoEnhancer 2.3
The new version of PhotoEnhancer features the method of "Multi-Scale Image Contrast Enhancement". This additional algorithm enhances locally the contrast of images, maximizing the available visual information. It can be applied to foggy scenes, aerial or satellite images, images with smoke or medical images.

GazoPa
GazoPa is a similar image search service on the web in private beta by Hitachi. Users can search images from the web based on user’s own photo, drawings, images found on the web and keywords. GazoPa enables users to search for a similar image from characteristics such as a color or a shape extracted from an image itself. There are abundant quantities of images on the web, however many of these simply cannot be described by keywords. Since GazoPa uses image features to search other similar images, a vast range of images can be retrieved from the web. GazoPa is a new visual search service that can navigate users to new territories on the web. http://www.gazopa.com/sign_in

Multimodal and Mobile Personal Image Retrieval: A User Study
These last months, I have been collaborating to a research project on Multimodal Information Retrieval of digital pictures collected through camera phones. Recently, one of the papers resuming the results of the research was presented at the International Workshop of Mobile Information Retrieval, held in conjunction with SIGIR in Singapore. Here goes the abstract and the URL to download the paper.
X. Anguera, N. Oliver, and M. Cherubini. Multimodal and mobile personal image retrieval: A user study. In K. L. Chan, editor, Prooceeding of the International Workshop on Mobile Information Retrieval (MobIR’08), pages 17–23, Singapore, 20-24 July 2008. [PDF]
Mobile phones have become multimedia devices. Therefore it is not uncommon to observe users capturing photos and videos on their mobile phones. As the amount of digital multimedia content expands, it becomes increasingly difficult to find specific images in the device. In this paper, we present our experience with MAMI, a mobile phone prototype that allows users to annotate and search for digital photos on their camera phone via speech input. MAMI is implemented as a mobile application that runs in real-time on the phone. Users can add speech annotations at the time of capturing photos or at a later time. Additional metadata is also stored with the photos, such as location, user identification, date and time of capture and image-based features. Users can search for photos in their personal repository by means of speech without the need of connectivity to a server. In this paper, we focus on our findings from a user study aimed at comparing the efficacy of the search and the ease-of-use and desirability of the MAMI prototype when compared to the standard image browser available on mobile phones today.

Adobe Photoshop Lightroom 2
Adobe Photoshop Lightroom 2 is best categorized as a Digital Processor. That is, from bringing images to your computer, cataloging them for later retrieval (and, if you want, backing them up to insure protection against accidental loss), enhancing and fine tuning your images, all the way to printing and/or digital distribution—one can do it all from Lightroom. However, one of the strongest reasons to use Lightroom is the opportunity for playing with images with no concern about how many versions and variations of the image you create without screwing up your original image. Any alteration you make on an image in Lightroom is only how Lightroom lets you "see" the image. Nothing is changed in the image itself unless you save a copy with those changes. The biggest negative about Lightroom is that the interface constantly changes, depending upon what you've clicked. This makes "hacking" the program a challenge, and working with Lightroom isn't helped by the manual that doesn't properly explain the conditions where you will see what is being explained. Despite the complex learning curve, there is much to like in Lightroom.

Neural Networks on C#
It is known fact, that there are many different problems, for which it is difficult to find formal algorithms to solve them. Some problems cannot be solved easily with traditional methods; some problems even do not have a solution yet. For many such problems, neural networks can be applied, which demonstrate rather good results in a great range of them. The history of neural networks starts in 1950-ies, when the simplest neural network's architecture was presented. After the initial work in the area, the idea of neural networks became rather popular. But then the area had a crash, when it was discovered that neural networks of those times are very limited in terms of the amount of tasks they can be applied to. In 1970-ies, the area got another boom, when the idea of multi-layer neural networks with the back propagation learning algorithm was presented. From that time, many different researchers have studied the area of neural networks, what lead to a vast range of different neural architectures, which were applied to a great range of different problems. For now, neural networks can be applied to such tasks, like classification, recognition, approximation, prediction, clusterization, memory simulation, and many other different tasks, and their amount is growing.
In this article, a C# library for neural network computations is described. The library implements several popular neural network architectures and their training algorithms, like Back Propagation, Kohonen Self-Organizing Map, Elastic Network, Delta Rule Learning, and Perceptron Learning. The usage of the library is demonstrated on several samples:
Classification (one-layer neural network trained with perceptron learning algorithms);
Approximation (multi-layer neural network trained with back propagation learning algorithm);
Time Series Prediction (multi-layer neural network trained with back propagation learning algorithm);
Color Clusterization (Kohonen Self-Organizing Map);
Traveling Salesman Problem (Elastic Network).
The attached archives contain source codes for the entire library, all the above listed samples, and some additional samples which are not listed and discussed in the article.
The article is not intended to provide the entire theory of neural networks, which can be found easily on the great range of different resources all over the Internet, and on CodeProject as well. Instead of this, the article assumes that the reader has general knowledge of neural networks, and that is why the aim of the article is to discuss a C# library for neural network computations and its application to different problems.

Special Issue: Advances in Medical Intelligent Decision Support Systems
Advances in Medical Intelligent Decision Support Systems.
Intelligent Decision Technologies (IDT) journal seeks original manuscripts
for a Special Issue on Advances in Medical Decision Support Systems scheduled to appear in Vol. 3, No. 2, 2009.The last few decades have witnessed significant advancements in intelligent computation techniques. Driven by the need to solve complex real-world problems, powerful and sophisticated intelligent data analysis technologies have been exploited or emerged, such as neural networks, support vector machines, evolutionary algorithms, clustering methods, fuzzy logic, particle swarm optimization, data mining, etc. In recent years, the volume of biological data has been increasing exponentially, thus, allowing significant learning and experimentation to be carried out using a multidisciplinary approach, which gives rise to many challenging problems. The foundation for any medical decision support is the medical knowledge base which contains the necessary rules and facts. This knowledge needs to be acquired from information and data in the fields of interest, such as medicine. Clinical decision-making is a challenging, multifaceted process. Its goals are precision in diagnosis and institution of efficacious treatment. Achieving these objectives involves access to pertinent data and application of previous knowledge to the analysis of new data in order to recognise patterns and relations. As the volume and complexity of data have increased, use of digital computers to support data analysis has become a necessity. In addition to computerisationof standard statistical analysis, several other techniques for computer-aided data classification and reduction generally referred to as intelligent systems, have evolved. This special issue will focus on illustrative and detailed information about medical intelligent decision support systems and feature extraction/selection for automated diagnostic systems.The focus of this special issue is on advances in medical intelligent decision support systems including determination of optimum classification schemes for the problem under study and also to infer clues about the extracted features. Topics include, but are not limited to, the following:
* Bioinformatics and Computational Biology
* Neural Networks, Fuzzy Logic Systems and Support Vector Machines in Biological Signal Processing

TinEye image search engine
TinEye is the first image search engine on the web to use image identification technology. Given an image to search for, TinEye tells you where and how that image appears all over the web—even if it has been modified.
Just as you are familiar with entering text in a regular search engine such as Google to find web pages that contain that text, TinEye lets you submit an image to find web pages that contain that image
Every day TinEye's spiders crawl the web for additional images. Using sophisticated pattern recognition algorithms, TinEye creates a unique and compact digital signature or 'fingerprint' for each one and adds it to the index.
When you want to find out where an image is being used on the web, you submit it to TinEye. The attributes of the image are analyzed instantly, and its fingerprint is compared to the fingerprint of every single image in the TinEye search index. The result? A detailed list of any websites using that image, worldwide.
Use TinEye to find out where and how an image appears on the web, even if it has been cropped or heavily modified.

Lire 0.7 Released
Lire 0.7 is a major release fixing a lot of bugs and introducing several new features including new descriptor, a simplified way to use descriptors by introducing new generic searchers and indexers as well as an generalized interface for image descriptors. There are also several improvements in indexing and search speed (especially in autocolorcorrelogram). Furthermore retrieval performance was optimized based on the Wang 1000 data set. If you use Lire 0.7 to update an existing version, please make sure that your indices are created newly from scratch. All new features have also found their way into LireDemo, which now also supports multi-threaded indexing.
