摘要：
We present a low bit-rate video compression system that integrates region-based motion estimation and motion compensation with spatio-temporal wavelet transform coding. The paper focusses on the motion segmentation module, which determines maximum likelihood estimates of region motion parameters employing the Expectation Maximization (EM) algorithm and mean field techniques. Preliminary results show the competitiveness of this approach.
