frequencycoefficients
将图像分为nxn的分块,之后将各分块三个颜色通道的直方图平均化,最后进行离散余弦变化,分别提取各通道低频系数(The image into nxn sub-block after block of all three color channels of the histogram equalization, and finally the discrete cosine change, were extracted from the low frequency coefficients of each channel)

NSGA-III
测试可以跑,根据自己情况修改下函数即可. NSGA-III 首先定义一组参考点。然后随机生成含有 N 个(原文献说最好与参考点个数相同)个体的初始种群,其中 N 是种群大小。接下来,算法进行迭代直至终止条件满足。在第 t 代,算法在当前种群 Pt的基础上,通过随机选择,模拟两点交叉(Simulated Binary Crossover,SBX)和多项式变异 产生子代种群 Qt。Pt和 Qt的大小均为 N。因此,两个种群 Pt和 Qt合并会形成种群大小为 2N 的新的种群 Rt=Pt∪Qt。 为了从种群 Rt中选择最好的 N 个解进入下一代,首先利用基于Pareto支配的非支配排序将 Rt分为若干不同的非支配层(F1,F2等等)。然后,算法构建一个新的种群St,构建方法是从 F1开始,逐次将各非支配层的解加入到 St,直至 St的大小等于 N,或首次大于 N。假设最后可以接受的非支配层是 L层,那么在 L+ 1 层以及之后的那些解就被丢弃掉了,且 St FL中的解已经确定被选择作为 Pt+1中的解。Pt+1中余下的个体需要从 FL中选取,选择的依据是要使种群在目标空间中具有理想的多样性。(The test can run and modify the function according to its own situation. NSGA-III first defines a set of reference points. Then the initial population containing N individuals (preferably the same number of reference points as the original literature) was randomly generated, where N was the size of the population. Next, the algorithm is iterated until the termination condition is satisfied. On the basis of current population Pt, the algorithm simulates two-point crossover (SBX) and polynomial mutation to produce offspring population Qt by random selection.)
