A new content-based mesh design algorithm for video objects segmentation and tracking is proposed. The algorithm moves the mesh nodes along motion or luminance discontinuities in order to ÿt the objects boundaries. The motion inside adjacent triangular cells is estimated by competitive forward-backward matching. This approach allows the displacements of the nodes without the remeshing of occlusion regions: uncovered background nor background to be covered. The mesh is deformed under thedoi:10.1016/j.sigpro.2004.04.003 fatcat:dtdmrn35c5fxhnlteei74u6y7i
