Title: People Detecting, Identifying and Searching in Video Surveillance and Multimedia Forensics

Abstract: Many results of pattern recognition research can be directly suitable for applications in video surveillance and multimedia forensics, concerning people security. The talk will present how some state-of-the art solutions, in classification, clustering, similarity search are exploitable for analyze the presence, the activity and the identity of persons in video. Recent advances in efficient search based on ''“particle'' windows” for detecting people shapes in image and video will be discussed. Then a short review of the state of the art of approaches for people re-identification in video footage will be presented, without covering aspects related with biometry, but underlying methods for assessing similarity of people appearance with 2D and 3D body models. Many possible applications for tracking people in cluttered and crowded context, searching for aspect similarities in real-time video surveillance and in off-line forensics will be illustrated.

Title: Texture Synthesis for Large Virtual Environments

Abstract: A major difficulty in building vast, rich virtual worlds is the large amount of content that is required, in particular 3d meshes and textures. It is therefore not surprising that researchers in computer graphics started to consider methods to automatically generate this content. Textures in particular have received much attention: Images of materials tend to occupy a large amount of memory and their content is often of a stochastic nature. On the one hand this randomness makes them hard to compress efficiently as images, but on the other hand one can hope to describe their content through algorithms. However, being able to compute textures of a given appearance only partially solves the problem: The generated data must also be available in a form allowing for high quality, interactive rendering. In this talk I will describe the major challenges we are facing when synthesizing content for virtual worlds. I will focus on textures, describing the main families of approaches for their synthesis. I will also discuss which data structures may be used to hold the data being continuously generated as the user explores the scene. Along the talk I will point out directions of future research in this area.


SLefebvre Short Bio - Sylvain Lefebvre is a researcher at INRIA, France. He completed his PhD in 2004, on the topic of texturing and procedural texture generation using GPUs. He joined Microsoft Research (Redmond, USA) as a postdoctoral researcher during the year 2005, where he worked with Hugues Hoppe on runtime parallel texture synthesis. Their synthesizer was the first to run entirely on the GPU, allowing for direct interaction with the synthesized patterns. In 2006 he was recruited by INRIA as a permanent researcher. He is currently a member of the team ALICE in the Nancy Grand-Est INRIA center. His main research focuses are in procedural content generation -- often starting from examples -- end-user content manipulation and compact GPU-friendly data structures for interactive applications and games. Sylvain contributed several data-structures for parameterization-free texturing, such as spatial hashes that can be efficiently accessed from the GPU. Sylvain is an active member of the computer graphics research community, serving on the paper’s committee of major conferences such as SIGGRAPH and EUROGRAPHICS. He was short-paper co-chair for EUROGRAPHICS 2011. In 2010, he was honored with the EUROGRAPHICS young researcher award for his work on texture synthesis and GPU data-structures. In his vanishing spare time, Sylvain is an avid gamer and hobbyist game developer.

Title: Morphological Filtering in Shape Spaces: Applications using Tree-Based Image Representations

Abstract: Connected operators are filtering tools that act by merging elementary regions of an image. A popular strategy is based on tree-based image representations: for example, one can compute a shape-based attribute on each node of the tree and keep only the nodes for which the attribute is sufficiently strong. This operation can be seen as a thresholding of the tree, seen as a graph whose nodes are weighted by the attribute. Rather than being satisfied with a mere thresholding, we propose to expand on this idea, and to apply connected filters on this latest graph. Consequently, the filtering is done not in the space of the image, but on the space of shapes build from the image. Such a processing is a generalization of the existing tree-based connected operators. Indeed, the framework includes classical existing connected operators by attributes. It also allows us to propose a class of novel connected operators from the leveling family, based on shape attributes. Finally, we also propose a novel class of self-dual connected operators that we call morphological shapings. Illustrations of the interest of the proposed approach will be provided on several tree-based image representations, including min-tree, max-tree, tree of shapes and hierarchical segmentations.


LNajman Short Bio - Laurent Najman received the Habilitation à Diriger les Recherches in 2006 from the University of Marne-la-Vallée, a Ph.D. of applied mathematics from Paris-Dauphine University in 1994 with the highest honour (Félicitations du Jury) and an “Ingénieur” degree from the Ecole des Mines de Paris in 1991. After earning his engineering degree, he worked in the Central Research Laboratories of Thomson-CSF for three years, working on some problems of infrared image segmentation using mathematical morphology. He then joined a start-up company named Animation Science in 1995, as director of research and development.
