Wavelet Video Coding Using Allpass Filters

图像和视频压缩是先进信息社会非常重要的基础技术之一。在这项研究中，我们提出了一种新的3D小波视频编码方案，其中基于ALLPASS的小波作为空间变换，提升格式与运动补偿相结合作为时间变换。实验结果表明，基于Allpass的正交对称小波性能优于传统的小波。

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.
