Here is the doc. I tried it on your image to get an ok result. You might have to play with the algorithm/parameters to get a thicker/more defined edge: Theme Copy img = imread ('binary_image.png'); I = rgb2gray (img); BW1 = edge (I,'sobel');

MATLAB: Canny Edge Detection Threshold Values Meaning

WebThe Canny method differs from the other edge-detection methods in that it uses two different thresholds (to detect strong and weak edges), and includes the weak edges in the output only if they are connected to strong edges. This method is therefore less likely than the others to be affected by noise, and more likely to detect true weak edges. WebJan 21, 2024 · I = imread('circuit.tif'); imshow(I) BW1 = edge(I,'Canny'); BW2 = edge(I,'Prewitt'); imshowpair(BW1,BW2,'montage') I = gpuArray(imread('circuit.tif')); BW … chins leeming
