9:00 - 10:00 Keynote presentation Behavior Imaging and the Study of Autism James Rehg, GeorgiaTech Beginning in infancy, individuals acquire the social and communication skills that are vital for a healthy and productive life. Children with developmental delays face great challenges in acquiring these skills, resulting in substantial lifetime risks. Children with an Autism Spectrum Disorder (ASD) represent a particularly significant risk category, due both to the increasing rate of diagnosis of ASD and its consequences. Since the genetic basis for ASD is unclear, the diagnosis, treatment, and study of the disorder depends fundamentally on the observation of behavior. Unfortunately, current methods for acquiring and analyzing behavioral data are so labor-intensive as to preclude their large scale application. In this talk, I will describe our research agenda in Behavior Imaging, which targets the capture, modeling, and analysis of social and communicative behaviors between children and their caregivers and peers. We are developing computational methods and statistical models for the analysis of vision, audio, and wearable sensor data. Our goal is to develop a new set of capabilities for the large-scale collection and interpretation of behavioral data. I will describe several research challenges in statistical modeling which arise in this area, and present illustrative results in the video-based analysis of social interactions. 10:00 - 10:15 Demo presentations Demonstrations and Live Evaluation for the Gesture Recognition Challenge Isabelle Guyon, Clopinet; Vassilis Athitsos, University of Texas at Arlington MoPaCo: High Telepresence Video Communication System Using Motion Parallax with Monocular Camera Ryo Ishii, Shiro Ozawa, Harumi Kawamura, Akira Kojima, NTT Corporation Mid-Air Interactive Display Using Modulated Display Light Zoran Zivkovic, Hendriek Groot Hulze, Trident Microsystems 10:15 - 11:15 Coffee break & Demos 11:15 - 12:15 Session 1: Tracking Real-Time Upper Body Tracking with Online Initialization using a Range Sensor Adolfo Lopez-Mendez, Marcel Alcoverro, Montse Pardas, Josep Casas, Technical University of Catalonia Real Time Feature Point Tracking with Automatic Model Selection Mircea Ionita, Philip Tresadern, Timothy Cootes, University of Manchester Using Segmented 3D Point Clouds for Accurate Likelihood Approximation in Human Pose Tracking Nicolas Lehment, Moritz Kaiser, Gerhard Rigoll, Technische Universitat Munchen 12:15 - 13:15 Session 2: Action Recognition Real-time Sign Language Letter and Word Recognition from Depth Data Dominique Uebersax, Juergen Gall, Michael Van den Bergh, ETH Zurich; Luc Van Gool, ETH Zurich, KU Leuven Robust Validation of Visual Focus of Attention using Adaptive Fusion of Head and Eye Gaze patterns Stylianos Asteriadis, Kostas Karpouzis, Stefanos Kollias, National Technical University of Athens Measuring and Reducing Observational Latency when Recognizing Actions Syed Zain Masood, Christopher Ellis, Adarsh Nagaraja, Marshall Tappen, Joseph LaViola, University of Central Florida; Rahul Sukthankar, Carnegie Mellon University 13:15 - 14:45 Lunch 14:45 - 16:05 Session 3: Applications Volumetric 3D Graphics on Commodity Displays using Active Gaze Tracking Charles Malleson,John Collomosse, University of Surrey Monocular Omnidirectional Head Motion Capture in the Visible Light Spectrum Jeroen Lichtenauer, Maja Pantic, Imperial College London Developer-Centred Interface Design for Computer Vision Gregor Miller, Sidney Fels, University of British Columbia Freehand 3D Scanning in a Mobile Environment using Video Patrick Wollner, Ognjen Arandjelovic, University of Cambridge 16:05- 16:30 Coffee break 16:30 - 17:00 Invited presentation Production Quality: Computer Vision for Commercial Gaming Nick Lord, Sony Computer Entertainment Europe 17:00 - 17:30 Invited presentation David Minnen, Oblong Industries, TBA 17:30 - 18:30 Panel discussion
