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?
Adding the source for reference: https://www.youtube.com/watch?v=C3EEy8adxvc Thank you in advance.
$\sum a^2
becomes $\sum a^2$, and$$\sum_{a=0}^{100} a^2$$
becomes $$\sum_{a=0}^{100} a^2$$. Try it out! also, youtube videos are usually not the best source to find information about math subjects – I've found several ones that are plain wrong but had literally millions of views. $\endgroup$ – Marcus Müller Mar 11 '19 at 8:25
