Abstract

In this paper, we present a video coding scheme which combines motion compensation (MC) based on irregular triangle meshes, wavelet transform (DWT) and zerotree coding. This scheme includes the possibility to use the wavelet transform conventionally (over the whole frame) or as a shape adaptive version (SADWT) applied to selected regions of the error image. We propose to transform regions which are formed by groups of triangles situated over parts of the error image with a high variance level. In this way it is possible to reduce the transmitted error information to areas where most motion takes place, which is especially useful in cases of a low bit-rate. As the regions can also consist in object shapes, this method also favors the object-based approach of our scheme. The transformation method results in a number of coefficients exactly the same as the number of pixels in the arbitrary shaped region, unless zerotree coding is performed over the whole frame. Results of applying this technique in a low bit-rate environment are presented at the end of the paper.
