Hello, I want to extract a sheetmetal-edge so that the rest of the picture is completely white. The edge is not completely rectangular it has a burr on both sides, how can I extract the sheetmetal? Attached is the image.

We want to do something very similar. We want to crop a leaf from its background. Did you figure out how to do yours? Attached is the image.
