Background: The question here is related to images in particular and not signal/waveforms.
I have been reading a lot of answers about the difference between convolution and correlation but I am stuck on my doubt as to how are they related to each other while performing operations. Most of the answers are individual answers for each of these terms.
A statement I am trying to understand says
Here correlation operations are performed by replacing the exhausted convolutions with element-wise multiplications using Discrete Fourier Transform (DFT).
I am not able to relate the individual definitions here. Can anyone please explain this?
