I'm currently processing a close up of the Rosette with no reliable background points. I eventually managed to get what I think is a decent result with just 4 points which I figured should be about the same level. However, it made me think if there could be a better way of doing it.
How about if you had a manual background extractor that assumes that the gradient in the image is a tilted linear plane. You could adjust the tilt of the assumed plane to be deducted from the image via a real-time preview until you got a result you're happy with. You could control the direction and amplitude of the tilt with either a virtual joystick or x and y sliders all centered at zero. You could run it on RGB/K or on R, G and B individually.
Sound like a good idea ?

Interesting idea. I use first order background models a lot with ABE, but with the "limitation" that you don't get to pick directly the reference points, and sometimes is hard to capture the right background areas. I would rather have that built into ABE, than manual sliders. Or have DBE work with various order models, rather than splines.
