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)
What is Canny edge method?
Canny edge detection is a technique to extract useful structural information from different vision objects and dramatically reduce the amount of data to be processed. It has been widely applied in various computer vision systems.
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.
