matlab示例程序，可以边缘检测、腐蚀、膨胀等基本操作，另外还可以对检测得到的边缘进行连接操作。,matlab example of the procedure, you can edge detection, corrosion, expansion of the basic operation of detection can also be operated to connect the edge.

canny edge detector. The program in matlab platform to achieve the best extraction of the canny edge operator extract the whole image edge pixel deputy. Which use Gaussian function to filter out the noise and the use of Gaussian operator of the first
