这是otsu算法的matlab版，可以对图像进行自动二值化处理。-Otsu algorithm matlab version, automatic binarization processing of the image.

利用matlab进行图片处理，用于图像灰度化和边缘检测以及二值化-Matlab image processing for image gray and edge detection and binarization

matlab的楚翔处理，色彩增强，二值滤波，旋转放大等功能，图像识别-the matlab Chu Xiang processing, color enhancement, binary filtering, rotation, zoom, image recognition

预处理后将得到一幅宽度为一个像素的细化二值图像，然后通过特定的端点和交叉点的特征进行指纹匹配。论文中采用MATLAB编程实现全部算法。-After pretreatment of a width of one pixel to obtain a binary image thinning, and through specific endpoint and the intersection of the characteristics of the fingerprint matching. T
