Edge detection algorithms have traditionally utilized the Gaussian Linear Filter (GLF) for image smoothing. Although GLF has very good properties in removing noise and unwanted artifacts from an image, it is also known to remove many valid edges. To cope with this problem, edge preserving ...

As phase congruency based edge detection method is insensitive to variations in image illumination, and it makes looking for the maxima in local energy become unnecessary, we get good experimental result on the location and accuracy of edge detection....

In this article, we have examined what edge detection/feature extraction looks like from a computer vision point of view using some predefined filters. It is worthy of note however that a CNN will not be using these predefined filters for edge detection, it will rather learn the best filters...
value is clamped to between 0.0 and 1.0. This operation is performed independently for each color component (including the alpha component). You can create many types of image processing effects using different weight matrices, such as blurring, sharpening, edge detection, translation, and embossing...
