WebJan 22, 2024 · We see that we get a similar result, except that the sum of the values in the result is 4, which is the highest value we can get by applying this filter. Thus, we know we found a pixel in a bottom vertical edge of our image because we got the highest value of 4.. To map these values back to the 0–1 range, we simply add 4 and then divide by 8, …
