Abstract :
This paper proposes a method for an accurate tracking of objects contained in video sequences thus allowing access and manipulation of video objects along the time. Each video object is represented both by a triangulated mesh and a polygonal mesh. The polygonal mesh results from a bottom up motion-based segmentation of a video sequence. This model is hierarchical: a video object plane (VOP) is the top of a segmentation pyramid. Each level in it is characterized by its proper quality of motion compensation. The triangulated mesh is a union of Delaunay meshes on each polygonal region of the VOP. Tracking is realized both on polygonal and triangulated meshes
