理解使用向量量化进行图像量化的原理：对序列中的许多样本进行联合量化，用一个值代替相似的一组值，减少量化误差；

掌握向量量化器码书设计的方法，此次实验使用LBG算法设计码书；

3. 对LBG算法的理解和使用；

4.Matlab矩阵数据的处理。-Understood that the use of vector quantization for image quantized principle: a number of samples of the sequence are jointly quantified, instead of a similar set of values ​ ​ with a value, to reduce the quantization error　master Vector quantizer codebook design, the experimental use LBG algorithm codebook design　3. LBG algorithm to understand and use　4.Matlab matrix data processing.
