功用：根据OTSU方法计算数字图像二值化的自适应阈值-function : According OTSU method of digital image binarization Adaptive Threshold

OTSU方法计算图像二值化的自适应阈值,算法对输入的灰度图像的直方图进行分析，将直方图分成两个部分，使得两部分之间的距离最大。划分点就是求得的阈值。 -OTSU method of adaptive image binarization threshold, the algorithm of the input histogram analysis of gray image, the histogram is divided into two parts, making the maxim

OTSU方法计算图像二值化的自适应阈值，OTSU 算法可以说是自适应计算单阈值（用来转换灰度图像为二值图像）的简单高效方法。-OTSU images calculated value of the two adaptive threshold, OTSU algorithm can be calculated adaptive threshold (for conversion to gray scale images binary images), a simple and efficient
