| Popis: | This paper presents a method for video sequence coding, using motion estimation over a triangular object-based mesh. We introduce a novel "crack line" notion to deal with motion discontinuities and to improve representation scalability. The optimization of the nodal motion vectors is performed by means of a multi-resolution differential method, further improved by "backward in forward" tracking. To illustrate the proposed methods, results concerning the motion compensation of a mesh are reported. |
