Canny
- Canny边缘检测算法: 用高斯滤波器平滑图像; 用一阶偏导的有限差分计算梯度的幅值和方向; 对梯度幅值进行非极大值抑制; 用双阈值算法检测和连接边缘。 -canny contour extraction algorithm
canny
- 图像的边缘检测的原理是检测出图像中所有灰度值变化较大的点,而且这些点连接起来就构成了若干线条,这些线条就可以称为图像的边缘。(The principle of edge detection of an image is to detect all the changes in the gray value of the image, and these points are connected to form a number of lines, these lines can be calle
