WISMA 2010 Deadline Extension - 11th International Workshop of the Multimedia Metadata Community

CALL for PAPERS Workshop on Interoperable Social
Multimedia Applications (WISMA 2010)

11th International Workshop of the Multimedia Metadata Community
http://dmag.ac.upc.edu/conferences/wisma2010/

Submission due: 14th March 2010 - Workshop dates: 19th-20th May 2010
Workshop venue: Universitat Politècnica de Catalunya, Barcelona (Spain)

In the Web 2.0, a growing amount of multimedia content is being shared on Social Networks. Due to the dynamic and ubiquitous nature of this content (and associated descriptors), new interesting challenges for indexing, access, and search and retrieval have arisen. In addition, there is a growing concern on privacy protection, as a lot of personal data is being exchanged. Teenagers (and even younger kids), for example, require special protection applications; while adults are willing to have a higher control over the access to content. Furthermore, the integration of mobile technologies with the Web 2.0 applications is also an interesting area of research that needs to be addressed; not only in terms of content protection, but also considering the implementation of new and enriched context-aware applications. Finally, social multimedia is also expected to improve the performance of traditional multimedia information search and retrieval approaches by contributing to bridge the semantic gap. The integration of these aspects,
however, is not trivial and has created a new interdisciplinary area of research. In any case, there is a common issue that needs to be addressed in all the previously identified social multimedia applications: the interoperability and extensibility of their applications. Thus, the workshop is particularly interested in research contributions based on standards.

Applied mathematics: The statistics of style

Nature 463, 1027-1028 (25 February 2010) -Published online 24 February 2010

Bruno A. Olshausen & Michael R. DeWeese

A mathematical method has been developed that distinguishes between the paintings of Pieter Bruegel the Elder and those of his imitators. But can the approach be used to spot imitations of works by any artist?

What makes the style of an artist unique? For paintings or drawings, what comes to mind are specific brush or pen strokes, the manner in which objects are shaded, or how characters or landscapes are portrayed. Art historians are skilled at identifying such details through visual inspection, and art collectors and museums currently rely on this type of expert analysis to authenticate works of art. Might it be possible to automate this process to provide a more objective assessment? Is it possible to teach a computer to analyse art? In an article in Proceedings of the National Academy of Sciences, Hughes et al.¹ demonstrate that subtle stylistic differences between the paintings of Pieter Bruegel the Elder and those of his imitators, which were at one time misattributed by art historians, may be reliably detected by statistical methods.

Hughes and colleagues' work is the latest in a stream of research findings that have emerged over the past few decades in the field of 'image statistics'. The players in this field are an unlikely cadre of engineers, statisticians and neuroscientists who are seeking to characterize what makes images of the natural environment different from unstructured or random images (such as the 'static' on a computer monitor or television). Answering this question is central to the problem of coding and transmitting images over the airwaves and the Internet, and, it turns out, it is just as important for understanding how neurons encode and represent images in the brain.

The first image statisticians were television engineers, who, as early as the 1950s, were trying to exploit correlations in television signals to compress the signals into a more efficient format. Around the same time, pioneering psychologists and neuroscientists such as Fred Attneave and Horace Barlow were using ideas from information theory to work out how the particular structures contained in images shape the way that information is coded by neurons in the brain. Since then, others have succeeded in developing specific mathematical models of natural-image structure — showing, for example, that the two-dimensional power spectrum varies with spatial frequency, f, roughly as 1/f² (ref. 2), and that the distribution of contrast in local image regions is invariant across scale^{3, 4, 5}.

Investigators also began applying these and related models to characterize the statistical structure of paintings by particular artists. It was shown, for example, that Jackson Pollock's drip paintings have fractal structure⁶, and that Bruegel's drawings could be distinguished from those of his imitators by the shape of the histogram of wavelet filter outputs, which represent how much spatial structure is present at different scales and orientations⁷. It is this latter work that formed the basis for Hughes and colleagues' study¹. Instead of using standard wavelet filters, they apply a set of filters that are adapted to the statistics of Bruegel's drawings through a method known as sparse coding.

In a sparse-coding model, local regions of an image are encoded in terms of a 'dictionary' of spatial features; importantly, the dictionary is built up, or trained, from the statistics of an ensemble of images, so that only a few elements from the dictionary are needed to encode any given region. Essentially, sparsity forces the elements of the dictionary to match spatial patterns that tend to occur in the images with frequencies significantly higher than chance, thus providing a snapshot of structure contained in the data. Neuroscientists have shown that such dictionaries, when trained on a large ensemble of natural scenes, match the measured receptive-field characteristics of neurons in the primary visual cortex of mammals. These and other empirical findings have lent support to the idea that sparse coding may be used by neurons for sensory representation in the cortex⁸.

Rather than attempting to form a generic code adapted to natural scenes, Hughes et al.¹ asked what sort of dictionary results from training on one specific class of image — the drawings of Pieter Bruegel the Elder. The dictionary that emerges, not surprisingly, differs from that adapted for natural scenes. In some sense, Hughes et al. have evolved an artificial visual system that is hyper-adapted to Bruegel's drawings. Such a visual system will be adept at representing other drawings from this class — that is, other authentic drawings by Bruegel — because they result in sparse encodings. However, it will not be so adept at representing images outside this class, such as drawings by other artists and even those attempting to imitate Bruegel, because they will result in denser encodings — more dictionary elements will be needed to describe each image region (Fig. 1). To put it another way, a picture may be worth a thousand words, but if it's an authentic Bruegel, it should take only a few Bruegel dictionary elements to represent it faithfully.

Figure 1: Sparse-coding analysis of artistic style.

Hughes and colleagues¹ show that small image patches taken from a collection of authentic works by Pieter Bruegel the Elder (a) can be used to generate a 'dictionary' of visual elements attuned to the statistics of his style (b). A test image (c) can then be authenticated by recreating it with a combination of dictionary elements. If recreation of the test image requires only a few dictionary elements, it is sparse, and labelled 'authentic', whereas if accurate encoding of the test image requires many dictionary elements, it is labelled as an 'imitation'.

High resolution image and legend (122K)

Can such an approach be used to authenticate works by any artist? And how robust can one expect it to be in practice? Key to the success of this study¹ is the fact that all of the analyses were performed on one particular type of artwork produced by Bruegel — drawings of landscapes. However, Bruegel worked in a variety of media, and his subject matter spanned a wide range of content. Moreover, an individual artist may use various styles. Developing algorithms capable of generalizing across these variations presents a much more challenging problem. Another concern is that it may be possible to defeat this method by generating images that are sparse for a wide range of dictionaries. For example, a geometrical abstract painting by Piet Mondrian would presumably yield a highly sparse representation using a dictionary trained on nearly any artist. Worse still, images randomly generated from the learned dictionary elements would also exhibit high sparsity but would look nothing like a real Bruegel. Thus, sparsity alone may be too fragile a measure for authentification.

One might question other technical choices made by the authors, such as the exclusive use of kurtosis (a statistical measure often used to quantify the degree of 'peakedness' of a probability distribution) to characterize the sparsity of filter outputs; and the analysis of statistical significance is at times puzzling. But Hughes and colleagues have taken a bold step. This is an exciting area of research that goes even beyond forgery detection. Indeed, it begs the question of whether it might be possible to fully capture the style of an artist using statistics. The field of natural-image statistics has advanced beyond the simple sparse-coding models used here, and it is now possible to characterize complex relationships among dictionary elements^{9, 10}. Intriguingly, all of these models are generative — that is, they can be used to synthesize images matching the statistics captured by the model, as has already been done successfully with textures¹¹. One exciting possibility is that computers could generate novel images that convincingly emulate the style of a particular artist. Perhaps someday the best Bruegel imitators will be computers.

Call for Papers

The purpose of the 3rd International Conference on Agents and Artificial Intelligence (ICAART) is to bring together researchers, engineers and practitioners interested in the theory and applications in these areas. Two simultaneous but strongly related tracks will be held, covering both applications and current research work within the area of Agents, Multi-Agent Systems and Software Platforms, Distributed Problem Solving and Distributed AI in general, including web applications, on one hand, and within the area of non-distributed AI, including the more traditional areas such as Knowledge Representation, Planning, Learning, Scheduling, Perception and also not so traditional areas such as Reactive AI Systems, Evolutionary Computing and other aspects of Computational Intelligence and many other areas related to intelligent systems, on the other hand.
A substantial amount of research work is ongoing in these knowledge areas, in an attempt to discover appropriate theories and paradigms to use in real-world applications. Much of this important work is therefore theoretical in nature. However there is nothing as practical as a good theory, as Boltzman said many years ago, and some theories have indeed made their way into practice. Informatics applications are pervasive in many areas of Artificial Intelligence and Distributed AI, including Agents and Multi-Agent Systems; This conference intends to emphasize this connection, therefore, authors are invited to highlight the benefits of Information Technology (IT) in these areas. Ideas on how to solve problems using agents and artificial intelligence, both in R&D and industrial applications, are welcome. Papers describing advanced prototypes, systems, tools and techniques and general survey papers indicating future directions are also encouraged. Papers describing original work are invited in any of the areas listed below. Accepted papers, presented at the conference by one of the authors, will be published in the Proceedings of ICAART with an ISBN. A book with the best papers of the conferene will be published by Springer-Verlag. Acceptance will be based on quality, relevance and originality. Both full research reports and work-in-progress reports are welcome. There will be both oral and poster sessions.
Special sessions, dedicated to case-studies and commercial presentations, as well as tutorials dedicated to technical/scientific topics are also envisaged: companies interested in presenting their products/methodologies or researchers interested in holding a tutorial are invited to contact the conference secretariat.

Duration: 4 to 6 months

Start Date: March / April 2010

Description

Xerox Research Centre Europe (XRCE) is currently developing advanced image retrieval prototypes that leverage different technologies for analyzing all visual aspects of and image namely: content, aesthetic and emotional value. The prototypes were developed within OMNIA (http://omnia.xrce.xerox.com/), a three year research project funded by the French government, and PinView (www.pinview.eu), a European Union funded project. The purpose of this internship, shared between the Work Practice Technology (WPT) and the Textual and Visual Pattern Analysis (TVPA) research groups is to port a version of one the image retrieval prototypes on a multi-touch table display and then participate in the conduct of a series of user preference and evaluation tests. The student will be involved both in the design and conduct of the tests, and in the subsequent analysis and presentation of the results.

The candidate should have knowledge of at least one of the following: flash/Flex, C#/.NET, or C++/C. Experience in the design and conduct of psychological experiments or Voice of Customer studies is not required but would be advantageous. The student should be fluent in French and have a good level of written English.

XRCE provides an informal and relaxed working environment situated in the Parc de Maupertuis in Meylan. The successful candidate will be given the freedom and flexibility to find their own solutions and to work in a way that suits them but will have the guidance and support of experienced full-time Xerox researchers and thereby gain an introduction to the field of commercial research in a world-class research laboratory.

A BPT Application: Semi-automatic Image Retrieval Tool

This work presents a semi-automatic tool for content retrieval. In contrast to traditional content based image retrieval systems that work with entire images, the
tool we have developed handles individual objects. The availability of a pool of pre-segmented objects found using region analysis allows the human behaviour of presegmentation to be replicated. To generate defined objects in the object pool, segmentation is performed using multidimensional Binary Partition Trees (BPTs). The tree structure uses colour, spatial frequency edge histograms to form semantically meaningful tree nodes. The BPTs can be intuitively browsed and are stored within XML documents for ease of access and analysis. To find an object a node from a query image is matched against the nodes of the BPT of the database image. These are matched according to a collection of MPEG-7 descriptors. Performance evaluation shows high quality segmentations and reliable retrieval
results.

The Google Image Treasure Hunt?

http://www.seobythesea.com/?p=3442
When a search engine indexes an image on the Web, it often has to rely upon the words that it finds associated with that picture. Those words could include the file name, alt text for the image, a caption, as well as other text on the same page.

Those words can be misleading, however, and search engines are trying other approaches to identifying the actual content contained within images. One of the approaches that Google has taken to index images is to have people play each other in a game to label those images. There’s a possibility that Google may add another image game, like the one seen in the screen shot below:

The new game from Google is described in a patent filing published this week, incorporating a way to identify objects within images. The patent application is:

Object Identification in Images
Invented by Yushi Jing, Michael Fink, Michele Covell, Shumeet Baluja
Assigned to Google
US Patent Application 20100034466
Published February 11, 2010
Filed: August 10, 2009

Google is doing more than using games to understand images, and has started using automated ways to compare images to each other to identify different features contained within those images. A couple of years ago, we saw a Google paper come out titled PageRank for Product Image Search, which described how Google might use that technology. You can see that image technology in action in Google Image Swirl, which came out in Google Labs in November of last year.

Interestingly, a couple of the writers listed on that paper are also listed as inventors of this patent application.

The patent tells us about the possibility of Google releasing an “image treasure hunt” game, where players look through images to identify a particular object within a particular image:

In one example, a particular image including a dog is selected as the target of the “image treasure hunt,” and users who are playing the game are told that the target is a dog. Users then proceed to search through images to find the particular image of the dog, which is the target of the “image treasure hunt.”

Each time a user identifies an image with the dog, the user indicates the location of the dog in the image to see whether that dog in the image is the target of the “image treasure hunt.” As users identify dogs in various images, the locations of dogs in various images is stored to enable retrieval later of each image based on a dog being included in the image. As such, the “image treasure hunt” helps catalog the types of objects included in images.

A person finding an object might be asked to click upon it, or trace its outline. It’s also possible that they would be asked to provide more details about the object. For instance, if the object searched for is a dog, a person finding it might indicate that it’s a particular breed of dog, or that it might be in a certain setting or performing some kind of activity, such as a German Shepherd playing Frisbee at the beach.

It’s possible that once an object has been identified in an image that future displays of that image might show a clickable region around the image that links to more information about the object within that image.

The patent also describes how this game might use incentives to encourage people to play, such as having contests that may or may not include prizes.

The images that might be used in this game could include photos, map images, and pictures from video. So it’s possible that Google could use this method of identifying objects within images to improve their image search, video search, and Google Maps.

Why would Google spend so much effort setting up a game to identify objects within images?

The inventor of the Google Image Labeler game, Luis von Ahn, has an interesting presentation that was given as a Google Tech Talk in 2006, titled Human Computation, where he describes the ability of humans to perform some tasks that are relatively easy for people and hard for computers.

Google Maps has a new feature this morning. If you go to Google Maps, and click on the green flask in the top right corner, you’ll see a new window open in the middle of your screen labeled Google Maps Labs. Amongst the features presently in the lab are:

• Drag ‘n’ Zoom
• Aerial Imagery
• Back to Beta
• Where in the World Game
• Rotatable Maps
• What’s Around Here?
• LatLng Tooltip
• LatLng Marker
• Smart Zoom

Kind of interesting that at least one of those is a game. Since the image treasure hunt could potentially be used with images associated with maps, it’s possible that we might see it appear within the Google Maps Labs applications. Since it could also be used to help improve image search and video search by having people identify objects in images and videos, it might spring up over at Google Labs.
