| Research Abstract |
Image and video compression is one of very important fundamental techniques for advanced information society. In this study, we have proposed a new scheme of 3D wavelet video coding, where the allpass-based wavelets are used as spatial transform, and the lifting scheme combined with motion compensation as temporal transform. We have shown from the experimental results that the allpass-based orthogonal symmetric wavelets can outperform the conventional wavelets.
