Hi!
I want to find all occurences of this symbol in an image and is currently using CORR2 with a function that steps pixel-by-pixel through a larger image and try to find this symbol. The problem i find is that there are multiples of this symbol partially overlapping which it doesnt recognize as the image i compare to has a white background. How can I make corr2 (or a similar setup) to only match based on the black arrms of the symbol and not the background?

Yep, I think my code (in my answer below) will find it. Did you even try it? If not, why not?

See attached demo that uses normxcorr2() to find a template in a larger image.

Try raising the threshold to make sure it gets regions that are only really VERY close to the template.
