Fill canny edges
WebYes, you provide a base image, the preprosessor generates a normal map or canny edge map from that input image. Then the controlnet model uses that generated map along with your prompt to create a new image. WebAug 22, 2024 · Not sure why beginners always want to do edge detection just because they can see an edge. What you want to do is to simply threshold and scan to find the first zero pixel. For each gray scale image, just call imbinarize and don't do any edge stuff: Theme. Copy. bw = imbinarize (grayImage); [rows, columns, numberOfColorChannels] = size (bw);
