Wavelet Video Coding Using Allpass Filters

图像和视频压缩是信息社会的重要基础技术之一。在这项研究中，我们提出了一种新的方案的三维小波视频编码，其中的全通基小波作为空间变换，提升方案结合运动补偿作为时间变换。实验结果表明，基于全通的正交对称小波的性能优于传统小波。

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.
