I wanted to understand the working of colfilt. When we provide the block size and function (ex.colfilt(img,[3 3],'fun');) does it make overlapping boxes if not how does the output image is of same size. If there is any document wherer I can find the mathematical explanation ?.
I will really appreciate for your help.

I agree it's confusing, so maybe that's why I've never found a need to use it. Supposedly it can make processing faster but since typical operations I do on an image take like a second or less, time has never been something I've worried about.
It looks like it has a 'distinct' (jumping by several pixels) option and a 'sliding' (move by 1 pixel) option.
