中文说明：本人毕设代码，这部分是用迭代方案实现的，该算法可以增强对比度，实现去雾，代码增加中文注释，还进行均值，方差，熵的统计，matlab2010下可运行，其他版本应该问题不大，毕竟是matlab吗。
English Description：
I completed the set code. This part is realized by iterative scheme, the algorithm can contrast enhancement, to realize the fog, code to increase Chinese annotation, mean, variance, entropy, matlab2010 can run. Other versions should be no problem, after all is the MATLAB?.
