Image background in image recognition
3 views (last 30 days)
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?
(Although image is attached it does not show, it is essentially a symbol with two crosses overlayed with one tilted 45 degrees.)
