迭代法阈值分割，迭代法自动计算最优阈值。已经写成函数形式，输入灰度图，输出分割好后的阈值图。-Threshold segmentation iterative method, iterative method for automatically calculating the optimal threshold. Function has been written in the form of input grayscale outpu

阈值分割是图像分割的常用方法,本程序用迭代法选取最优阈值对图像进行分割-Thresholding is a common method of image segmentation, the iterative selection procedure using the optimal threshold for image segmentation
