Hi Nils,

Thank you for this explanation, this sounds plausible for me. I converted to 
grayscale because I thought that this would be easier to deal with at the 
beginning (just need to calculate with one value instead of three and so on) 
but if each band is processed individually this makes it much easier for me 
because I don't have to care what mode the image has.

Thank you, best regards,
Philipp Bender
