I'm implementing the Sobel Edge Detector image filter. I don't need help with writing the actual code for the filter. The filter is supposed to multiply each pixel by two convolution masks , where do the values for these masks come from? I can't find any explanations on this online. Here is an explanation of the filter:
If anyone is familiar with it or can look at it and tell me what the values for the masks should be that would be excellent, thanks.
