Hello, I had search around and found out this link to auto crop https://opencv-code.com/quick-tips/auto-cropping-image-with-arbitrary-background-color/
but I had tried here from my image to crop only the color section but failed. Reading the code it looks like should be arbitrary select the background color but maybe I'm wrong. I'm attaching my image here, if anyone can give me a hint, I can try to test and do some coding here
appreciate on help
