I don't know how to write 'summation' symbol here hence posting the picture.
Can someone explain to me the difference between i,j and u,v in this explanation of correlation and convolution?
I know this discussion must have taken place somewhere but it is difficult to look for such discussion by keyword 'correlation' and convolution'.
I have already referred to the following posts: 1. Difference between correlation and convolution on an image? 2. What is the difference between convolution and cross-correlation?
