请注意，这些数字是“最佳”的情况：我们正在测试三个编码器都为峰值信噪比做了专门优化，而这也正是VP8编码器规范当前做的。

Note that these Numbers are a "best-case" situation: we're testing all three optimized for PSNR, which is what the current VP8 encoder specializes in as well.

提出了一种基于小波变换域的块匹配运动估计搜索的新算法，模拟实验表明，利用此算法可获得比一般运动块匹配方法更大的峰值信噪比，具有更好的性能复杂度比。

The authors present a new algorithm for block-matching motion estimation based on wavelet transform. The simulation shows that this algorithm has better PSNR and performance-to-complexity ratio.

实验还讨论了候选区、阈值与击中值域块个数、编码时间和峰值信噪比(PSNR)间的关系。

The relationship among the candidate region, threshold, hit range blocks, encoding time and PSNR is discussed by the experiments.
