中文说明：采用粒子群矢量量化算法生成图像矢量量化的最优码书，可以任意设定种群数与迭代代数。程序结果产生最优码书与平均误差。
English Description：
The particle swarm vector quantization algorithm is used to generate the optimal codebook of image vector quantization, and the number of population and iteration algebra can be arbitrarily set. The result of the program produces the optimal codebook and the average error.
