Multi-view video coding (MVC), supported in part by THOMSON Corporate Research

l    Analyze motion/disparity in multi-view video to achieve efficient search schemes for MVC

l    Analyze focus mismatches in multiview system based on camera parameters and scene depths

l    Design/analyze efficient depth-related compensation techniques for focus mismatches

l    Develop adaptive reference filtering (ARF) approach for video coding with focus mismatches

l    Complexity analysis and reduction for ARF in MVC inter-view coding

l    JVT activities: Propose ARF as a coding tool for MVC and establish core experiments (CE)

l    Design introductory assignments for the lab-based class.

l    Assist students in assignments and final projects with TI signal processing boards.

l    Evaluate the final projects.
