Abstract

We present an approach to a unified representation of motion and shape of objects in a video scene. Starting from given object masks, we outline an algorithm for the construction of grids consisting of regular and/or curved triangles. Hence the object shape is given as a polygon or a number of consecutive arcs, while the object motion can be approximated through tracking of the grid points. The prediction images are finally rendered by warping a reference frame according to the deformed grid.
