How does Canny edge detection work?
The principle is simple: the algorithm goes through all the points on the gradient intensity matrix and finds the pixels with the maximum value in the edge directions.
Which is the best edge detection algorithm?
Canny edge detection algorithm (Canny, 1986) known as optimal edge detection algorithm and the most commonly used edge detection algorithm in practice.
What is Canny edge detection OpenCV?
Canny Edge Detection is used to detect the edges in an image. It accepts a gray scale image as input and it uses a multistage algorithm. You can perform this operation on an image using the Canny() method of the imgproc class, following is the syntax of this method. Canny(image, edges, threshold1, threshold2)
