Paper Abstract

The two most important aims in video coding are to receive a good quality on one hand and a low bit-rate on the other hand. To combine these almost contradictory requirements it is necessary to use a motion compensation technique which has good subjective transformation characteristics and does not need the transmission of much more than motion information. This paper presents a motion compensation scheme based on 2D triangle meshes with irregularly spread node points. The nodes are selected with the same method on encoder and decoder sides, so that the only information that has to be transmitted are motion vectors and very low bit- rates can be achieved. In a second approach, this model is extended to a technique which adapts particular meshes to the objects in the scene and performs individual transformations. In this way it is possible to compensate motion discontinuities and to improve subjective and objective quality over traditional motion compensation schemes without too costly computational procedures.
