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
