Web26 jul. 2024 · Once again, we can use the math above to fill in a picture showing us what is happening at the level of the image and the kernel. We can see by lining up the appropriate kernel indices with the input image indices that we end up with the kernel “facing the original direction” i.e. in cross-correlation the kernel is not flipped.
