说明：  感兴趣区域提取。根据人感兴趣的区域对图像进行裁减(Region of interest extraction. According to people interested in the process of reducing the region' s image)

说明：  用动量梯度下降法训练BP网络 已知输入向量为P=[-1,-2,3,1 -1,1,5,3]，目标输出为T=[-1,-1,1,1]。 (Gradient descent with momentum BP network training input vector is known as P = [-1,-2,3,1 -1,1,5,3], the target output for the T = [-1,-1,1, 1].)

原始lmd算法，效果很不好，不知道程序哪里写错,不太能运行，自己做修改，但是上面的算法比较明确(The original LMD algorithm, the effect is very bad, I don t know where the program is misspelled,but it really can not run.If you want run it,just change a little.Actally the algorithm is clear.)
