Abstract :
This paper presents a scalable affine core (SAG) that can be used for video object motion compensation. MPEG standardization committee recommends affine transformation for 2D mesh-based video object motion tracking, where the object is modeled as 2D mesh with triangular patches. The motion tracking is a texture warping for the deformed patches from a frame-to-frame. A mesh-based video motion compensation architecture is presented. The motion compensation architecture uses the proposed SAC to track the deformation of a 2D mesh-based video object. Performance study is conducted and it shows that the proposed SAC can be used in online MPEG-4 mobile applications
