WebAug 28, 2024 · 2. In your answer the gradients are swapped. They should be edges_y = filters.sobel_h (im) , edges_x = filters.sobel_v (im). This is because sobel_h finds horizontal edges, which are discovered by the derivative in the y direction. You can see the kernel used by the sobel_h operator is taking the derivative in the y direction. WebWhether you represent the gradient as a 2x1 or as a 1x2 matrix (column vector vs. row vector) does not really matter, as they can be transformed to each other by matrix transposition.
