用ＣＡＮＮＡＹ算子对图象进行边缘提取，初学者有一定参考价值-With CANNAY operator of image edge extraction, beginners have a certain reference value

This a program to extraction edge from a color image-This is a program to extraction edge from a color image

1.边缘检测，分别用Sobel, Laplacian-Gaussian 方法对一幅灰度图像进行边缘提 取，并给出对比结果； 2.灰度阈值分割：利用双峰法对一幅灰度图像进行灰度分割处理。-1. Edge detection, respectively Sobel, Laplacian-Gaussian methods on a gray-scale image edge extraction, and gives comparative results 2. Gray threshold

图像处理种常用的一阶微分算子，主要实现图像的边缘检测和提取。 -Image processing is a kind of commonly used first order differential operator, mainly to achieve the image edge detection and extraction.
