In this paper, a new hybrid wavelet video coding algorithm combined with H.263 and significance-linked connected component analysis (SLCCA) for very low bit rate application has been proposed. In the proposed algorithm, first, fine-tuned motion estimation of H.263 has been used to reduce temporal redundancy, and exhaustive overlapped block motion compensation has been used to ensure the coherency in motion compensation error frames. Second, the wavelet transform is applied in the motion compensation error frames to achieve global energy compaction. Third, the wavelet coefficients are organized and represented by SLCCA. Last, the horizontal and vertical components of motion vectors are encoded by adaptive arithmetic coding. The proposed algorithm has been tested on both Class-A sequences Akiyo and Class-B sequences Foreman (QCIF) and achieved satisfied performance
