Abstract

The problem of tracking of triangulated meshes for Video Object Planes in video sequences is considered. Triangulated meshes are constructed on the basis of hierarchical region- based models of VOP. The mesh is articulated, that is each polygonal region in a VOP is Delaunay triangulated separately and all partial meshes are connected in the global triangulation. Nodal optical flow is computed from motion parameters of associated regions according to an affine motion model using a hierarchy of region-based models. The tracking of such a VOP along video sequence is based on a full region based tracking of a hierarchical region-based model of a VOP. A forward tracking scheme and a backward motion compensation for a hybrid coding are proposed. Experimental results for a complex articulated VOP are presented.
