English Description：
MATLAB training program (Canny edge detection) I have no direct calls to the system function, that would spoil the water. My Matlab code is actually very easy to translate c/c + +. Canny edge detection of a total of four parts: 1. the Gaussian smoothing the original image 2. Sobel edge detection of the Gaussian-smoothed image. Also need to maintain horizontal and vertical joint, so a total of three needed Sobel edge detection image. 3. Sobel test image of the joint is non-maximal suppression 4. connection points and hysteresis thresholding.
