Description: Gray Level Edge Thinning Method
Abstract. An effective edge thinning algorithm is important in image segmentation and object identification since it increases the possibility of success in detecting objects in the image and saves the processing time in the further steps such as labeling and image transformation. We investigate some gray level edge thinning method that is based on the gradient magnitude within 3x3 local neighborhood. The new method has been tested with various types of images the real world. Experimental results show that this method produces more accurate images than those of the popular non-maximum suppression methods do.

Description: 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)) Platform: |
