The Canny filter is a multi-stage edge detector. It uses a filter based on the derivative of a Gaussian in order to compute the intensity of the gradients.The Gaussian reduces the effect of noise present in the image. Then, potential edges are thinned down to 1-pixel curves by removing non-maximum pixels of the gradient magnitude.

Jan 25, 2019 · The Canny edge detector is an edge detection operator that uses a multi-stage algorithm to detect a wide range of edges in images. It was developed by John F. Canny in 1986. Canny also produced a computational theory of edge detection explaining why the technique works.

12.05.2021 · Canny edge detection results. Let’s put the Canny edge detector to work for us. Start by accessing the “Downloads” section of this tutorial to retrieve the source code and example images. From there, open a terminal and execute the following command: $ python opencv_canny.py --image images/coins.png.
