最后，导出了反映矢量量化器工作特性和率失真函数之间的数量关系的不等式串。

Finally, a series of inequalities is derived, which gives a quantitative relation between the performance of a vector quantizer and rate-distortion function.

实验结果表明，我们获得的码本具有较好的通用性，能够针对不同统计特性的图像进行良好的矢量量化。

The experiment result show that the code table which is made by image Lena can fit for many different statistic feature images to make vector quantizations.

在矢量量化和小波变换的结合方面，提出了一种基于视觉特性的小波变换跨带矢量量化压缩编码方案，并通过实验验证了算法的性能；

Based on the former two theories, we propose a wavelet transform cross-band vector quantization based on human vision, and we verify the correction with experimentation.
