....motion compensation. There are two reasons for this choice: At the time of subjective testing, OBASC was not able to outperform the block based reference coder for scenes with complex motion. Furthermore, the computational complexity of source models allowing flexible motion [8] 9] 12] [13] is significantly higher than block based motion compensation. Since MPEG 4 defines a video decoder, the problem of image analysis was avoided by using presegmented video sequences named VO s as coder input. This decision allowed the development of an object based video coder. Although automatic ....

....plane. The motion data associated with the 2D dynamic mesh representation is determined by estimating forward motion vectors for mesh node point sequentially from one frame to the next, which is generally referred to as forward tracking. Various techniques have been proposed for to achieve this [22], 5] 8] 23] 10] Although multi resolution and hierarchical motion estimation methods have been discussed widely in literature to improve efficiency and accuracy of motion estimation, hierarchical mesh based motion estimation has been addressed only for the case of uniform meshes [7] 2] ....
