Is it possible to make relative Backgroud Extraction according to Star Photometry in RGB images?
The idea is:
- background is additive signal in image, it is added to the background and to the stars signal
- if you have enough stars in the image and you make star photometry on them, you can compute relative additive signal around many stars in image
- then you can use this to compute a background model which will be subtracted from image to correct the background
I don't know if the star photometry precision is good enough to compute a correct background model. But maybe somebody will know or try to find this out.
