		jdhwosnhw 10 months ago \| parent \| context \| favorite \| on: Show HN: Fast and Exact Algorithm for Image Mergin... The parent comment said nothing about using deep learning. Convolution is not the same as using a CNN. I interpreted their comment as meaning they used a 2D convolution (presumably a 2D cross correlation, actually) to find regions of overlap

Yes you're right it was a 2D cross-correlation which is very analogous to a convolution

If memory serves… the only difference is that one of the kernels being convolved is reversed for convolution.
