RES: computing the interactions between real and virtual objects in video sequences

International audiencePossibilities for dynamic interactions of people with machines created by combination of virtual reality and communication networking provide new interesting problems at the intersection of two domains (among others): Computer Vision and Computer Graphics. In this paper, a technical solution to one of these problems is presented to automate the mixing of real and synthetic objects in a same animated video sequence. Current approaches usually involve mainly 2D-based eeects and rely heavily on human expertise and interaction. We aim at achieving a close binding between 3D-based analysis and synthesis techniques to compute the interaction between a real scene captured in a sequence of calibrated images, and a computer-generated environment
