ClustTour By CERTH-ITI

ClustTour is a better way to search, discover and browse interesting city areas, POIs and events. Whether you are planning a trip or just want to check out how a place looks like, ClustTour offers a large collection of photos, maps and descriptions. You may wonder, what's new in this? ClustTour is not based on "official" guides and "experts" but on how people like you capture what is interesting everyday.


Key Features:
* Explore over 30 cities with new cities added regularly.
* Browse and search in areas, spots, POIs and events views.
* See groups of photos, descriptions and where they are on the map.
* The map interactively groups spots for easier browsing. Zoom in and
out to see more or less.
* Search the Web with a single tap to learn more about the spot you browse.
* Mark your favorites for easy review and sharing.
* Enjoy the most interesting spots in every city!

iPhone Screenshot 1iPhone Screenshot 2
How it works:
ClustTour applies advanced analysis technologies to large-scale anonymous user contributions to discover the most interesting locations and events. These range from famous landmarks, such as the Thessaloniki's White Tower, to events and activities like music concerts, shopping, bookcrossing and partying but also off-the-beaten-path spots, from hidden eateries to local artists collections. Every city area, POI and event is connected to informative photo groups, descriptions and search options when you want to learn more.
Everything in ClustTour is automatic. And when we say everything we mean everything! There is no human intervention in selecting areas, spots, events and photos. Well-tuned algorithms select what is most interesting based on people contributions. This way, sometimes, we might miss well-known landmarks (in any case you know where to find these) and some of the spots do not fully make sense but this way we find the hidden gems and we are sure that what ClustTour offers is what people and not what officials and experts think!

Vision Algorithm to Automatically Parse Addresses in Google Street View

Reprinted from http://www.popsci.com/technology/article/2011-12/google-wants-computer-vision-algorithms-can-read-addresses-street-view?utm_medium=referral&utm_source=pulsenews

Extracting Door Numbers Building numbers come in a huge variety of shapes, colors and sizes, making them difficult to model for machine vision. Netzer et al

Extrapolating numbers and letters from digital images is still a tough task, even for the best computer programmers. But it would be handy to extract business names, or graffiti, or an address from pictures that are already stored online. Aiming to make its Street View service even more accurate, Google would like to extract your house number from its own Street View photo cache.

Say what you will about Street View (and Helicopter View and Amazon View and etc.) — beyond the novelty factor, the images are full of potentially useful data. Using street numbers on the side of a house or business could make navigation programs more accurate, and help motorists or pedestrians find the right door by providing a preview on the Internet or a mobile device. But while handwriting algorithms are pretty advanced, software systems are still limited in their ability to extract information from images. Factors like blurring, lighting and other distortions can be a problem.

To improve matters, researchers at Google and Stanford devised a new feature-learning algorithm for a set of street numbers captured from a Street View database. They used 600,000 images from various countries and extracted the house numbers using a basic visual algorithm. Then the team used Amazon’s Mechanical Turk system to verify the arrangement of the numbers. The result was two sets of images: One with house number images as they appeared, and one with house numbers all resized to the same resolution.

Initially, traditional handcrafted visual learning algorithms didn’t work very well to extract the numbers. Next, the Google-Stanford team tried feature learning algorithms, which use various sets of parameters to learn recognition patterns. The new feature learning methods worked much better than the regular visual learning method: One of the algorithms (a K-means-based feature learning system) achieved 90 percent accuracy, compared to 98 percent for a human.

The system still needs improvement, but it could be useful for extracting number data from billions of images, the researchers say. Ultimately, this could make Street View a lot more accurate. Without a house-number-based view, an address in Street View is a default panorama, which might not actually be the address you want. Type in “30 Rockefeller Plaza,” for instance, and the first thing you see is a chocolatier next to the 30 Rock observation deck. You have to click and drag to see the NBC building.

“With the house number-based view angle, the user will be led to the desired address immediately, without any further interaction needed,” the paper authors explain.

sFly: Search and Rescue of Victims in GPS-Denied Environments (no Vicon, no Laser, No GPS!)

Final demo of the sFly European Project (2009-2011). This demo simulate a search and rescue in an outdoor GPS-denied factory environment. No laser, no GPS are used for navigation and mapping, but just a single camera and IMU onboard each vehicle. All the processing runs onboard, on a Core2Duo.
Three quadrocopters take off using visual SLAM, explore the environment, build a 3D map of it, and use it to localize themselves and potential victims by measuring the signal strengths of WiseNodes carried by each victim.

MPEG news: a report from the 98th meeting, Geneva, Switzerland

Re-Print from http://multimediacommunication.blogspot.com/ (Author: Christian Timmerer)

MPEG news from its 98th meeting in Geneva, Switzerland with less than 140 characters and a lot of acronyms. The official press release is, as usual,here. As you can see from the press release, MPEG produced significant results, namely:

  • MPEG Dynamic Adaptive Streaming over HTTP (DASH) ratified
  • 3D Video Coding: Evaluation of responses to Call for Proposals
  • MPEG royalty free video coding: Internet Video Coding (IVC) + Web Video Coding (WebVC)
  • High Efficiency Coding and Media Delivery in Heterogeneous Environments:MPEG-H comprising MMT, HEVC, 3DAC
  • Compact Descriptors for Visual Search (CDVS): Evaluation of responses to the Call for Proposals
  • Call for requirements: Multimedia Preservation Description Information (MPDI)
  • MPEG Augmented Reality (AR)

As you can see, a long list of achievements within a single meeting but let's dig inside. For each topic I've also tried to provide some research issues which I think are worth to investigate both inside and outside MPEG. 

MPEG Dynamic Adaptive Streaming over HTTP (DASH): DASH=IS ✔

As the official press release states, the MPEG ratifies its draft standard for DASH and it comes better, the standard should become publicly available which I expect to happen somewhat early next year, approx. March 2012, or maybe earlier. I say "should" because there is no guarantee that this will actually happen but signs are good. In the meantime, feel free using our software to play around and we expect to update it to the latest version of the standard as soon as possible. Finally, IEEE Computer Society Computing Now has put together a theme on Video for the Universal Web featuring DASH.
Research issues: performance, bandwidth estimation, request scheduling (aka adaptation logic), and Quality of Service/Experience.

3D Video Coding: 3DVC=CfP eval ✔

MPEG evaluated more than 20 proposals submitted as a response to the call issued back in April 2011. The evaluation of the proposal comprised subjective quality assessments conducted by 13 highly qualified test laboratories distributed around the world and coordinated by the COST Action IC1003 QUALINET. The report of the subjective test results from the call for proposals on 3D video coding will be available by end of this week. MPEG documented the standardization tracks considered in 3DVC (i.e., compatible with MVC, AVC base-view, HEVC, ...) and agreed on a common software based on the best-performing proposals.
Research issues: encoding efficiency of 3D depth maps and compatibility for the various target formats (AVC, MVC, HEVC) as well as depth map estimation at the client side.

MPEG royalty free video coding: IVC vs. WebVC

In addition to the evaluation of the responses to the call for 3DVC, MPEG also evaluated the responses to the Internet Video Coding call. Based on the responses, MPEG decided to follow up with two approaches namely Internet Video Coding (IVC) and Web Video Coding (WebVC). The former - IVC - is based on MPEG-1 technology which is assumed to be royalty-free. However, it requires some performance boosts in order to make it ready for the Internet. MPEG's approach is a common platform called Internet video coding Test Model (ITM) which serves as the basis for further improvements. The latter - WebVC - is based on the AVC constrained baseline profile which performance is well-known and satisfactory but, unfortunately, it is not clear which patents of the AVC patent pool apply to this profile. Hence, a working draft (WD) of WebVC will be provided (also publicly available) in order to get patent statements from companies. The WD will be publicly available by December 19th.
Further information:

Research issues: coding efficiency with using only royalty free coding tools whereby the optimization is first towards royalties and then efficiency.

MPEG-H

A new star is born which is called MPEG-H referred to as "High Efficiency Coding and Media Delivery in Heterogeneous Environments" comprising three parts: Pt. 1 MMT, Pt. 2 HEVC, Pt. 3 3D Audio. There's a document called context and objective of MPEG-H but I can't find out whether it's public (I come back later on this).

Part 1: MMT (MPEG Media Transport) is progressing (slowly) but a next step should be definitely to check the relationship of MMT and DASH for which an Ad-hoc Group has been established (N12395), subscribe here, if interested.
Research issues: very general at the moment, what is the best delivery method (incl. formats) for future multimedia applications? Answer: It depends, ... ;-)
Part 2: HEVC (High-Efficiency Video Coding) made significant progress at the last meeting, in particular: only one entropy coder (note: AVC has two, CABAC and CAVLC which are supported in different profiles), 8 bit decoding (could be also 10 bit, probably done in some profiles), specific integer transform, stabilized and more complete high-level syntax and HRD description (i.e., reference picture buffering, tiles, slices, and wavefronts enabling parallel decoding process). Finally, a prototype has been demonstrated decoding HEVC in software on an iPad 2 at WVGA resolution and the 10min Big Buck Bunny sequence at SD resolution with avg. 800 kbit/s which clearly outperformed the corresponding AVC versions.
Research issues: well, coding efficiency, what else? The ultimative goal to have a performance gain of more than 50% compared to the predecessor which is AVC.

Part 3: 3D Audio Coding (3DAC) is in its early stages but there will be an event during San Jose meeting which will be announced here. As of now, use cases are provided (home theatre, personal TV, smartphone TV, multichannel TV) as well as candidate requirements and evaluation methods. One important aspect seems to be user experience for highly immersive audio (i.e., 22.2, 10.2, 5.1) including bitstream adaptation for low-bandwidth and low-complexity.
Research issues: sorry, I'm not really an audio guy but I assume it's coding efficiency, specifically for 22.2 channels ;-)

Compact Descriptors for Visual Search (CDVS)


For CDVS, responses to the call for proposals (from 10 companies/institutions) have been evaluated and a test model has been established based on the best performing proposals. The next steps include the improvement of the test model towards for inclusion in the MPEG-7 standard.
Research issues: descriptor efficiency for the intended application as well as precision on the information retrieval results.

Multimedia Preservation Description Information (MPDI)


The aim of this new work item is to provide "standard technology helping users to preserve digital multimedia that is used in many different domains, including cultural heritage, scientific research, engineering, education and training, entertainment, and fine arts for long-term across system, organizational, administrative and generational boundaries". It comes along with two public documents, the current requirements and a call for requirements which are due at the 100th MPEG meeting in April 2002.
Research issues: What and how to preserve digital multimedia information?

Augmented Reality (AR)

MPEG's newest project is on Augmented Reality (AR), starting with an application format for which a working draft exists. Furthermore, draft requirements and use cases are available. These three documents will be available on Dec 31st.
Research issues: N/A

ACRI 2012 Santorini Island, Greece, 24-27 September 2012

Cellular automata (CA) present a very powerful approach to the study of spatio-temporal systems where complex phenomena build up out of many simple local interactions. They account often for real phenomena or solutions of problems, whose high complexity could unlikely be formalised in different contexts.

Furthermore parallelism and locality features of CA allow a straightforward and extremely easy parallelisation, therefore an immediate implementation on parallel computing resources. These characteristics of the CA research resulted in the formation of interdisciplinary research teams. These teams produce remarkable research results and attract scientists from different fields.

The main goal of the 10th edition of ACRI 2012 Conference (Cellular Automata for Research and Industry) is to offer both scientists and engineers in academies and industries an opportunity to express and discuss their views on current trends, challenges, and state-of-the art solutions to various problems in the fields of arts, biology, chemistry, communication, cultural heritage, ecology, economy, geology, engineering, medicine, physics, sociology, traffic control, etc.

Topics of either theoretical or applied interest about CA and CA-based models and systems include but are not limited to:

  • Algebraic properties and generalization
  • Complex systems
  • Computational complexity
  • Dynamical systems
  • Hardware circuits, architectures, systems and applications
  • Modeling of biological systems
  • Modeling of physical or chemical systems
  • Modeling of ecological and environmental systems
  • Image Processing and pattern recognition
  • Natural Computing Quantum Cellular Automata
  • Parallelism

This edition of the ACRI conference also hosts workshops on recent and important research topics on theory and applications of Cellular Automata like the following: Crowds and Cellular Automata (3rd edition), Asynchronicity and Traffic and Cellular Automata.

Terrain Surveillance Coverage using Cognitive Adaptive Optimization

A centralized cognitive‐based adaptive methodology for optimal surveillance coverage using swarms of MAVs has been developed, mathematically analyzed and tested using extensive simulation experiments. The methodology has been successfully tested on a large variety of 2D and 3D non‐convex unknown environments. Moreover, the methodology has been applied using real‐data from the Birmensdorf test area and the ETHZ’s hospital area. A decentralized version of the methodology has been also proposed and evaluated for the 2D case.

Google Scholar Citations Open To All

Article from http://googlescholar.blogspot.com/2011/11/google-scholar-citations-open-to-all.html

A few months ago, we introduced a limited release of Google Scholar Citations, a simple way for authors to compute their citation metrics and track them over time. Today, we’re delighted to make this service available to everyone! Click here and follow the instructions to get started.
Here’s how it works. You can quickly identify which articles are yours, by selecting one or more groups of articles that are computed statistically. Then, we collect citations to your articles, graph them over time, and compute your citation metrics - the widely used h-index; the i-10 index, which is simply the number of articles with at least ten citations; and, of course, the total number of citations to your articles. Each metric is computed over all citations and also over citations in articles published in the last five years.
Your citation metrics will update automatically as we find new citations to your articles on the web. You can also set up automated updates for the list of your articles, or you can choose to review the suggested updates. And you can, of course, manually update your profile by adding missing articles, fixing bibliographic errors, and merging duplicate entries.
As one would expect, you can search for profiles of colleagues, co-authors, or other researchers using their name, affiliation, or areas of interest, e.g., researchers at US universities or researchers interested in genomics. You can add links to your co-authors, if they already have a profile, or you can invite them to create one.
You can also make your profile public, e.g., Alex Verstak, Anurag Acharya. If you choose to make your profile public, it can appear in Google Scholar search results when someone searches for your name, e.g., [alex verstak]. This will make it easier for your colleagues worldwide to follow your work.
We would like to thank the participants in the limited release of Scholar Citations for their detailed feedback. They were generous with their time and patient with an early version. Their feedback greatly helped us improve the service. The key challenge was to make profile maintenance as hands-free as possible for those of you who prefer the convenience of automated updates, while providing as much flexibility as possible for those who prefer to curate their profile themselves.
Here is hoping that Google Scholar Citations will help researchers everywhere view and track the worldwide influence of their own and their colleagues’ work.

ColorHug

Read more at http://www.hughski.com/

The ColorHug is an open source display colorimeter. It allows you to calibrate your screen for accurate color matching.

The ColorHug is a small accessory that measures displayed colors very accurately. It is held on your display and plugged into a spare USB port on the computer for the duration of the calibration.

Have you ever taken a photo and wondered why it does not look the same on your screen as it did the camera?

It's probably because the LCD display on your computer has never been calibrated. This means colors can look washed-out, tinted with certain shades or with different color casts.

About 2 years ago I began working on color management in Linux. It soon became apparent that there was no integrated color management system. The color management support which did exist was often disabled by default in many applications. I have worked hard to make calibrating displays easy ever since. It is my goal to make color management accessable to end users. The hardware for color managing screens was bulky, slow and expensive. With a background in electronics, I thought I could create a device which was smaller, faster and cheaper.

Using the ColorHug it takes about a minute to take several hundred measurements from which the client software creates an ICC color profile. This color profile file can then be saved and used to make colors look correct on your monitor.

Face Recognition Makes the Leap From Sci-Fi

Article from THE NEW YORK TIMES

FACIAL recognition technology is a staple of sci-fi thrillers like “Minority Report.”

But of bars in Chicago?

SceneTap, a new app for smart phones, uses cameras with facial detection software to scout bar scenes. Without identifying specific bar patrons, it posts information like the average age of a crowd and the ratio of men to women, helping bar-hoppers decide where to go. More than 50 bars in Chicago participate.

As SceneTap suggests, techniques like facial detection, which perceives human faces but does not identify specific individuals, and facial recognition, which does identify individuals, are poised to become the next big thing for personalized marketing and smart phones. That is great news for companies that want to tailor services to customers, and not so great news for people who cherish their privacy. The spread of such technology — essentially, the democratization of surveillance — may herald the end of anonymity.

And this technology is spreading. Immersive Labs, a company in Manhattan, has developed software for digital billboards using cameras to gauge the age range, sex and attention level of a passer-by. The smart signs, scheduled to roll out this month in Los Angeles, San Francisco and New York, deliver ads based on consumers’ demographics. In other words, the system is smart enough to display, say, a Gillette ad to a male passer-by rather than an ad for Tampax.

Those endeavors pale next to the photo-tagging suggestion tool introduced by Facebookthis year. When a person uploads photos to the site, the “Tag Suggestions” feature uses facial recognition to identify that user’s friends in those photos and automatically suggests name tags for them. It’s a neat trick that frees people from the cumbersome task of repeatedly typing the same friends’ names into their photo albums.

“Millions of people are using it to add hundreds of millions of tags,” says Simon Axten, a Facebook spokesman. Other well-known programs like Picasa, the photo editing software from Google, and third-party apps like PhotoTagger, from face.com, work similarly.

But facial recognition is proliferating so quickly that some regulators in the United States and Europe are playing catch-up. On the one hand, they say, the technology has great business potential. On the other, because facial recognition works by analyzing and storing people’s unique facial measurements, it also entails serious privacy risks.

Using off-the-shelf facial recognition software, researchers at Carnegie Mellon University were recently able to identify about a third of college students who had volunteered to be photographed for a study — just by comparing photos of those anonymous students to images publicly available on Facebook. By using other public information, the researchers also identified the interests and predicted partial Social Security numbers of some students.

“It’s a future where anonymity can no longer be taken for granted — even when we are in a public space surrounded by strangers,” says Alessandro Acquisti, an associate professorof information technology and public policy at Carnegie Mellon who directed the studies. If his team could so easily “infer sensitive personal information,” he says, marketers could someday use more invasive techniques to identify random people on the street along with, say, their credit scores.

Today, facial detection software, which can perceive human faces but not identify specific people, seems benign.

Some video chat sites are using software from face.com, an Israeli company, to make sure that participants are displaying their faces, not other body parts, says Gil Hirsch, the chief executive of face.com. The software also has retail uses, like virtually trying out eyeglasses at eyebuydirect.com, and entertainment applications, like moustachify.me, a site that adds a handle bar mustache to a face in a photo.

But privacy advocates worry about more intrusive situations.

Now, for example, advertising billboards that use facial detection might detect a young adult male and show him an ad for, say, Axe deodorant. Companies that make such software, like Immersive Labs, say their systems store no images or data about passers-by nor do they analyze their emotions.

But what if the next generation of mall billboards could analyze skin quality and then publicly display an ad for acne cream, or detect sadness and serve up an ad for antidepressants?

Nano-spring make transparent, super-stretchy skin-like sensors

Article from:

 http://www.sciencecodex.com/read/stanford_researchers_build_transparent_superstretchy_skinlike_sensor-80227

article-0-0E85B7F000000578-63_468x260

When the nanotubes are airbrushed onto the silicone, they tend to land in randomly oriented little clumps. When the silicone is stretched, some of the "nano-bundles" get pulled into alignment in the direction of the stretching.

When the silicone is released, it rebounds back to its original dimensions, but the nanotubes buckle and form little nanostructures that look like springs.

"After we have done this kind of pre-stretching to the nanotubes, they behave like springs and can be stretched again and again, without any permanent change in shape," Bao said.

Stretching the nanotube-coated silicone a second time, in the direction perpendicular to the first direction, causes some of the other nanotube bundles to align in the second direction. That makes the sensor completely stretchable in all directions, with total rebounding afterward.

Additionally, after the initial stretching to produce the "nano-springs," repeated stretching below the length of the initial stretch does not change the electrical conductivity significantly, Bao said. Maintaining the same conductivity in both the stretched and unstretched forms is important because the sensors detect and measure the force being applied to them through these spring-like nanostructures, which serve as electrodes.

The sensors consist of two layers of the nanotube-coated silicone, oriented so that the coatings are face-to-face, with a layer of a more easily deformed type of silicone between them.

The middle layer of silicone stores electrical charge, much like a battery. When pressure is exerted on the sensor, the middle layer of silicone compresses, which alters the amount of electrical charge it can store. That change is detected by the two films of carbon nanotubes, which act like the positive and negative terminals on a typical automobile or flashlight battery.

The change sensed by the nanotube films is what enables the sensor to transmit what it is "feeling." Whether the sensor is being compressed or extended, the two nanofilms are brought closer together, which seems like it might make it difficult to detect which type of deformation is happening. But Lipomi said it should be possible to detect the difference by the pattern of pressure.

Using carbon nanotubes bent to act as springs, Stanford researchers have developed a stretchable, transparent skin-like sensor. The sensor can be stretched to more than twice its original length and bounce back perfectly to its original shape. It can sense pressure from a firm pinch to thousands of pounds. The sensor could have applications in prosthetic limbs, robotics and touch-sensitive computer displays. Darren Lipomi, a postdoctoral researcher in Chemical Engineering and Zhenan Bao, associate professor in Chemical Engineering, explain their work.

With compression, you would expect to see sort of a bull's-eye pattern, with the greatest deformation at the center and decreasing deformation as you go farther from the center.

"If the device was gripped by two opposing pincers and stretched, the greatest deformation would be along the straight line between the two pincers," Lipomi said. Deformation would decrease as you moved farther away from the line.

Bao's research group previously created a sensor so sensitive to pressure that it could detect pressures "well below the pressure exerted by a 20 milligram bluebottle fly carcass" that the researchers tested it with. This latest sensor is not quite that sensitive, she said, but that is because the researchers were focused on making it stretchable and transparent.

"We did not spend very much time trying to optimize the sensitivity aspect on this sensor," Bao said.

"But the previous concept can be applied here. We just need to make some modifications to the surface of the electrode so that we can have that same sensitivity."

Artificial intelligence community mourns John McCarthy

Article from http://www.bbc.co.uk/news/technology-15444222

John McCarthyArtificial intelligence researcher, John McCarthy, has died. He was 84.

The American scientist invented the computer language LISP.

It went on to become the programming language of choice for the AI community, and is still used today.

Professor McCarthy is also credited with coining the term "Artificial Intelligence" in 1955 when he detailed plans for the first Dartmouth conference. The brainstorming sessions helped focus early AI research.

Prof McCarthy's proposal for the event put forward the idea that "every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it".

The conference, which took place in the summer of 1956, brought together experts in language, sensory input, learning machines and other fields to discuss the potential of information technology.

Other AI experts describe it as a critical moment.

"John McCarthy was foundational in the creation of the discipline Artificial Intelligence," said Noel Sharkey, Professor of Artificial Intelligence at the University of Sheffield.

"His contribution in naming the subject and organising the Dartmouth conference still resonates today."

LISP

Prof McCarthy devised LISP at Massachusetts Institute of Technology (MIT), which he detailed in an influential paper in 1960.

The computer language used symbolic expressions, rather than numbers, and was widely adopted by other researchers because it gave them the ability to be more creative.

"The invention of LISP was a landmark in AI, enabling AI programs to be easily read for the first time," said Prof David Bree, from the Turin-based Institute for Scientific Interchange.

"It remained the AI language, especially in North America, for many years and had no major competitor until Edinburgh developed Prolog."

Regrets

In 1971 Prof McCarthy was awarded the Turing Award from the Association for Computing Machinery in recognition of his importance to the field.

He later admitted that the lecture he gave to mark the occasion was "over-ambitious", and he was unhappy with the way he had set out his new ideas about how commonsense knowledge could be coded into computer programs.

However, he revisted the topic in later lectures and went on to win the National Medal of Science in 1991.

After retiring in 2000, Prof McCarthy remained Professor Emeritus of Computer Science at Stanford University, and maintained a websitewhere he gathered his ideas about the future of robots, the sustainability of human progress and some of his science fiction writing.

"John McCarthy's main contribution to AI was his founding of the field of knowledge representation and reasoning, which was the main focus of his research over the last 50 years," said Prof Sharkey

"He believed that this was the best approach to developing intelligent machines and was disappointed by the way the field seemed to have turned into high speed search on very large databases."

Prof Sharkey added that Prof McCarthy wished he had called the discipline Computational Intelligence, rather than AI. However, he said he recognised his choice had probably attracted more people to the subject.

Throwable Camera Creates 360-Degree Panoramic Images

Article from http://mashable.com/2011/10/25/throwable-ball-camera/

Are you, like so many others, tired of all those old-fashioned cameras you have to hold in order to take pictures? Well here’s a camera you get to throw.

The Throwable Panoramic Ball Camera is a foam-padded ball studded with 36 fixed-focus, 2-megapixel mobile phone camera modules capable of taking a 360-degree panoramic photo.

You use the camera by throwing it directly in the air. When the camera reaches the apex — measured by an accelerometer in the camera — all 36 cameras automatically take a picture. These distinct pictures are then digitally stitched together and uploaded via USB where they are presented in a spherical panoramic viewer. This lets users interactively explore their photos including a zoom function.

 

SEE ALSO: The Development of the Camera: From Ancient to Instant [INFOGRAPHIC]

The results — as seen in the video above — are pretty darn impressive, but the Ball Camera is definitely not meant for shaky hands. Any spin on the ball when it’s thrown could distort the final image and you certainly wouldn’t want to drop the thing despite its 3D-printed foam padding. The 2-megapixel cameras are adequate but the quality drops as soon as users try to zoom in on distant elements. Besides, it looks a little difficult to fit the thing into a purse, let alone your pocket.

Right now, the Throwable Panoramic Ball Camera is not available to buy, though its creators have it pending a patent. Cool idea, but is it practical? Would you ever buy a camera you could throw? Let us know in the comments.

Rendering Synthetic Objects into Legacy Photographs

Kevin Karsch, Varsha Hedau, David Forsyth, Derek Hoiem
To be presented at SIGGRAPH Asia 2011

Abstract

We propose a method to realistically insert synthetic objects into existing photographs without requiring access to the scene or any additional scene measurements. With a single image and a small amount of annotation, our method creates a physical model of the scene that is suitable for realistically rendering synthetic objects with diffuse, specular, and even glowing materials while accounting for lighting interactions between the objects and the scene. We demonstrate in a user study that synthetic images produced by our method are confusable with real scenes, even for people who believe they are good at telling the difference. Further, our study shows that our method is competitive with other insertion methods while requiring less scene information. We also collected new illumination and reflectance datasets; renderings produced by our system compare well to ground truth. Our system has applications in the movie and gaming industry, as well as home decorating and user content creation, among others.

FaceLight – Silverlight 4 Real-Time Face Detection

This article describes the simple facial recognition method that searches for a certain sized skin color region in a webcam snapshot. This technique is not as perfect as a professional computer vision library like OpenCV and the Haar-like features they use, but it runs in real time and works for most webcam scenarios.

Kinect Object Datasets: Berkeley's B3DO, UW's RGB-D, and NYU's Depth Dataset

Articlw from http://quantombone.blogspot.com/2011/10/kinect-object-datasets-berkeleys-b3do.html

Why Kinect?

The Kinect, made by Microsoft, is starting to become quite a common item in Robotics and Computer Vision research.  While the Robotics community has been using the Kinect as a cheap laser sensor which can be used for obstacle avoidance, the vision community has been excited about using the 2.5D data associated with the Kinect for object detection and recognition.  The possibility of building object recognition systems which have access to pixel features as well as 2.5D features is truly exciting for the vision hacker community!

 


Berkeley's B3DO

First of all, I would like to mention that it looks like the Berkeley Vision Group jumped on the Kinect bandwagon.  But the data collection effort will be crowdsourced -- they need your help!  They need you to use your Kinect to capture your own home/office environments and upload it to their servers  This way, a very large dataset will be collected, and we, the vision hackers, can use machine learning techniques to learn what sofas, desks, chairs, monitors, and paintings look like.  They Berkeley hackers have a paper on this at one of the ICCV 2011workshops in Barcelona, here is the paper information:

Allison Janoch, Sergey Karayev, Yangqing Jia, Jonathan T. Barron, Mario Fritz, Kate Saenko, Trevor Darrell
ICCV-W 2011
[pdf] [bibtex]


UW's RGB-D Object Dataset

On another note, if you want to use 3D for your own object recognition experiments then you might want to check out the following dataset: University of Washington's RGB-D Object Dataset.  With this dataset you'll be able to compare against UW's current state-of-the-art.

 

In this dataset you will find RGB+Kinect3D data for many household items taken from different views.  Here is the really cool paper which got me excited about the RGB-D Dataset:


A Scalable Tree-based Approach for Joint Object and Pose Recognition
Kevin Lai, Liefeng Bo, Xiaofeng Ren, and Dieter Fox
In the Twenty-Fifth Conference on Artificial Intelligence (AAAI), August 2011.


NYU's Depth Dataset

I have to admit that I did not know about this dataset (created by by Nathan Silberman of NYU), until after I blogged about the other two datasets.  Check out the NYU Depth Dataset homepage. However the internet is great, and only a few hours after posted this short blog post, somebody let me know that I left out this really cool NYU dataset.  In fact, it looks like this particular dataset might be at the LabelMe-level regarding dense object annotations, but with accompanying Kinect data.  Rob Fergus & Co strike again!

Panasonic unveils first robotic hairdresser

The annual CEATEC technology in Tokyo gives Japanese technology companies a chance to let their hair down and show off robots far, far too odd for Western consumption.
Robot unicyclists and 'robot companions' are regulars at the show - often unveiled by otherwise normal technology companies. This year, Panasonic unveiled the first robotic hairdresser - as well as a robot 'doctor'.
Panasonic's robot hair washer uses advanced robot 'fingers' to massage the scalp while washing your head with jets of water and soap - rather like a car wash for your skull.

“Practical Image and Video Processing Using MATLAB®”

 

ref=as_li_ss_tl

This is the first book to combine image and video processing with a practical MATLAB(R)-oriented approach in order to demonstrate the most important image and video techniques and algorithms. Utilizing minimal math, the contents are presented in a clear, objective manner, emphasizing and encouraging experimentation.

The book has been organized into two parts. Part I: Image Processing begins with an overview of the field, then introduces the fundamental concepts, notation, and terminology associated with image representation and basic image processing operations. Next, it discusses MATLAB(R) and its Image Processing Toolbox with the start of a series of chapters with hands-on activities and step-by-step tutorials. These chapters cover image acquisition and digitization; arithmetic, logic, and geometric operations; point-based, histogram-based, and neighborhood-based image enhancement techniques; the Fourier Transform and relevant frequency-domain image filtering techniques; image restoration; mathematical morphology; edge detection techniques; image segmentation; image compression and coding; and feature extraction and representation.

Part II: Video Processing presents the main concepts and terminology associated with analog video signals and systems, as well as digital video formats and standards. It then describes the technically involved problem of standards conversion, discusses motion estimation and compensation techniques, shows how video sequences can be filtered, and concludes with an example of a solution to object detection and tracking in video sequences using MATLAB(R).

Extra features of this book include:

More than 30 MATLAB(R) tutorials, which consist of step-by-step guides to exploring image and video processing techniques using MATLAB(R)

Chapters supported by figures, examples, illustrative problems, and exercises

Useful websites and an extensive list of bibliographical references

This accessible text is ideal for upper-level undergraduate and graduate students in digital image and video processing courses, as well as for engineers, researchers, software developers, practitioners, and anyone who wishes to learn about these increasingly popular topics on their own.

Congratulations to DEMIR research team for winning the ImageCLEF-MED 2011 Ad-hoc image-based retrieval task using CEDD!!!!

Abstract. This paper present the details of participation of DEMIR  (Dokuz Eylul University Multimedia Information  Retrieval) research team to the context of our participation to the ImageCLEF 2011 Medical Retrieval task.  This year, we evaluated fusion and re-ranking method which is based on the best low level feature of images with best text retrieval result. We improved results by examination of different weighting models for retrieved text data and low level features. We tested multi–modality image retrieval in ImageCLEF 2011 medical retrieval task and obtained the best seven ranks in mixed retrieval, which includes textual and visual modalities. The results clearly show that proper fusion of different modalities improve the overall retrieval performance.
