canny边缘检测，对学习canny的同学有所帮助，opencv实现的！-canny edge detection, to help students to learn canny opencv realized!

基于canny算子和形态学的边缘检测方法，此方法对于边缘检测效果较为明显-Edge detection method based on morphology

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
