代码说明:

  读入一幅256*256图像,将它分成8*8pixel的若干块,对每块做DCT变换,保留Z型顺序的若干变换系数,进行IDCT重构图像,计算重构图像的信噪比(Reading a 256* 256 image, it will be divided into several blocks of 8*8 pixel, keep each optimal Z transformation of sequence number, IDCT transform coefficient calculation reconstruction image reconstruction images,and the signal-to-noise ratio)

    免疫遗传算法流程为: (1)随机产生初始父代种群A1 (2)根据先验知识抽取疫苗。 (3)若当前种群中已包含最佳个体,算法结束;否则进行以下步骤。 (4)根据抗体浓度和适应度进行复制。 (5)对当前第K代父代种群AK进行交叉操作,得到种群BK。 (Immune genetic algorithm process as follows: (1) randomly generated initial parent population A1 (2) vaccine based on a priori knowledge extraction. (3) If the current population already contains the best individuals, the algorithm ends otherwise, perform the following steps. (4) be reproduced in accordance with antibody concentration and fitness. (5) the population AK Present Generation K parent cross was obtained population BK.)
