WebThere are two main noticeable differences between Canny filter and other edge detectors. First, the others algorithm usually output broad lines (edges) while Canny filter outputs one-pixel-wide line(s) which represents the most probable edge position [Russ2011]. Second, the Canny filter combines several steps together while other filters have ... WebApr 23, 2024 · When using a Sobel Edge Detector, it is first best to convert the image from an RGB scale to a Grayscale image. Then from there, we will use what is called kernel convolution. A kernel is a 3 x 3 matrix consisting of differently (or symmetrically) weighted indexes. This will represent the filter that we will be implementing for an edge detection.
