二值化算法，含otsu,niblack,kapur,kittlerMet等方法-Binarization algorithm, including otsu, niblack, kapur, kittlerMet and other methods

图像二值化算法：Otsu算法，Kittler minimum error thresholding算法，Niblack二值化算法。都是很经典的二值化算法，可用于对图像进行二值化，我自己编写的并经过测试正确。附件中有算法使用说明。-Image binarization algorithm: Otsu method, Kittler minimum error thresholding method, and Niblack method. All these methods are classic
