指纹识别系统 源码，包括预处理，去噪声，二值化-Fingerprint Identification System source code, including pretreatment, to noise, the value of two.

基于opencv的车牌识别源码，使用了canny算法进行边缘检测，然后二值化，接着用cvFindContours搜索轮廓，最后从找到的轮廓中根据角点的个数，角的度数和轮廓大小确定，矩形位置。-Opencv-based license plate recognition source code, using the canny edge detection algorithm, and then two values, followed by cvFindContours search profi
