经典二值化算法 Niblack的改进

用matlab实现的otsu全局二值化算法、kittler 最小分类错误(minimum error thresholding)全局二值化算法、niblack局部二值化算法-Using matlab implementation otsu global binarization algorithm, kittler minimum classification error (minimum error thresholding) the global binarization algorithm

效果最好的三种二值化的方法 otsu niblack等 是自适应阈值方法-The best effect of three kinds of binarization methods otsu niblack, etc Is the adaptive threshold value method。
