Joint tracking of polygonal and triangulated meshes of objects in moving sequences with time varying content

This paper proposes a method for tracking of objects contained in video sequences. Each video object is represented both by a triangulated mesh and a polygonal mesh. The tracking of such models along a moving sequence is based on a full region-based polygonal tracking. The triangulated mesh is a union of Delaunay meshes on each polygonal region of the 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. Tracking of triangulated meshes is based on detecting and indexing new objects in the video scene along the time in a polygonal tracking phase.
