1. an advantage of wavelet-based video compression is that it offers more graceful image degradation at high compression ratios, and it also eliminates the block artifacts seen in dct compression
   由小波变换编码实现的视频压缩在具备高压缩比的基础上，仍拥有较高的主观视觉效果，避免了由分块dct变换引起的方块效应。
2. by choosing non-hybrid dictionary, blocking artifacts of dct system can be avoided ultimately . the cost of coding motion information is reduced, so the visual quality of images at low bit-rates is improved . 4
   而且，通过选择非晶格结构的字典(原子函数之间允许重叠)，从根本上避免了低速率dct系统带来的方块边缘失真，增加估计的精度，减少对运动信息编码耗费并提高在低速率下的视觉效果。
3. experimental results show that blocking artifacts has been effectively mitigated at low bit-rates in comparing with dct based method and the proposed coding scheme is better than 3d-spiht for the scene of video sequences that move rapidly
   仿真实验结果表明,与基于dct的方法相比,能够有效降低低比特率下重建视频的块失真,对运动场景变化较大的视频序列,压缩性能优于基于小波变换的3d-spiht方法。
4. the analysis on the method shows that an advantage of wavelet-based video compression coding is that it offers more graceful image degradation at high compression ratios, and it also eliminates the block artifacts seen in dc compression . and it can solve the contradiction between limited bandwidth and infinitude requirements of increasing customers in present communication system
   该系统充分利用人眼的视觉特性来减少帧内和帧间的冗余信息，能够消除传统图像编码的方块效应、蚊子效应等现象实现高压缩比，高质量的图像编码，可较好地解决现行通信系统中有限带宽与日趋增加的无限用户需求之间的矛盾。
5. there exit two methods to compress stereo video, block-based method and block-based method . block-based method has the merits of simplicity, robustness and being easy to be implemented in hardware, but blocking artifacts may exist and the visual effect of reconstruction image may be bad in low bit rates
   立体视频编码可以采用传统的块基编码方法和基于对象的编码方法，块基编码的优点是算法简单、稳健性高，易于硬件实现，但会出现块效应，在低比特率下重建图像的主观视觉效果很差。
