Thanks @crackwitz Yep, if you remove the open test 5 works but then others fail
I’ve been able to find a method (either changing the threshold/morph or how I pic the max contour) that makes each picture work independently but I’ve not been able to find what approach will work for the most type of images.
Maybe the answer is to have several different strategies for different types of images and then focus on building something that recognizes what type of image the user uploaded (a different problem that i’ve not yet thought about).
I was hoping that there was just a better way to approach the problem out there…
