根据CNNAY算法的4个步骤
1. 用高斯滤波器平滑图像;(图像去噪)
2. 用一阶偏导有限差分计算梯度幅值和方向;(特征增强)
3. 对梯度幅值进行非极大值抑制 ;(边缘检测)
4. 用双阈值算法检测和连接边缘。(形态学处理)
编写的边缘检测程序,简单实用(There are four parts of Canny edge detection:
1. smoothing the image with Gauss filter; (image denoising)
2. calculate gradient amplitude and direction by first order partial derivative finite difference method (feature enhancement)
3. non maximum suppression of the gradient amplitude; (edge detection)
4. detect and connect edges with double threshold algorithm. (morphological treatment))
