This paper presents an object-based, object-scalable mesh design and tracking algorithm for very low bitrate video coding, which consists of three stages: object segmentation, object boundary coding, and 2D mesh design and tracking within each object. Here, we use pre- segmented test sequences; hence, object/motion segmentation is not treated. The boundary of each individual object is approximated by a polygon. Next, a node point selection algorithm followed by constrained Delauney triangulation is employed, where line segments representing the boundary of the object polygons from the constraints.
