I think I got it. I'll put for example green dots on red background and use compare + maxima to determine the coordinates. Let's see how it works.

The dots would be physical dots, not marked afterwards to the image. The idea is that with some physical markers a software could automatically determine these positions and crop accordingly without any human interaction.

That doesn't really help since there shouldn't be any manual interaction. Also the area is not a rectangle.
