Heechan Park and Graham R. Martin, Video Compression : Wavelet Based Coding and Texture Synthesis Based Coding , June, 2005
This report introduces the emerging Wavelet-based video coding system. Inefficiency of the block-based motion estimation in context of the wavelet coder is discussed in comparison to the mesh-based approach. A progressive mesh refinement technique using multiple layers is proposed also a fast motion estimation based on the redundant wavelet is presented that outperforms a full-search motion estimation in both computation requirement and motion accuracy. Finally, the two-component texture synthesis algorithm is explored in connection with recently developed technique using GMM and LM to model and estimate transformation. The texton and ICA is briefly explained as alternatives.
