摘要

我们解决了高效编码视频序列的问题。提出了一种新的基于分块运动估计的混合自适应运动搜索算法(HAMS)，利用不同的小波/小波包类型对误差帧进行分解，然后对系数进行阈值化和编码。新系统在良好的压缩比下实现了合理的PSNR。

Hybrid adaptive motion search with wavelet/wavelet packet based motion residual video coding

We address the problem of efficiently encoding video sequences. A new system is proposed that overcomes the temporal redundancy by a new block based motion estimation called the hybrid adaptive motion search algorithm (HAMS), different wavelet/wavelet packet types are used for decomposition of the error frames, then the coefficients are thresholded and encoded. The new system achieves a reasonable PSNR at good compression ratios.
