使用opencv实现最大类间距离、最大熵和迭代法求图像二值化阈值，供大家参考；-Using opencv achieve maximum class distance, maximum entropy and iterative method for image binarization threshold, for your reference

图像分割是图像识别的基础，最大熵阈值分割可以很好的将图像分割出来-Image segmentation is the basis of image recognition, maximum entropy thresholding segmentation can be a very good out
