I'm a fairly new user to the Vision Development Module. I have a set of images that I need to find an area that is free of markings/scuffs. I'd like to use something like the find pattern VIs to find a black area in my image. When I try either of the match pattern or match geometric pattern VIs, while specifying a totally black match image, I get an error in Vision Assistant.
I've attached an example of an image that I've processed. I need to find an area that is open (no existing letters/scuffs, area is black). I'd rather not find all the bright objects and then manually parse through that array, if there is an easier way to find an area lacking bright objects or to find an area that is black.
