Sometimes, I need to export an image or two from the buffer so that I may process it elsewhere. However, some apps don’t accept floating point for one reason or another. Mostly, this is because I don’t have the programming chops to extend that app to do what I want.
E.g., I would like to use pnmclahe, which only accepts 8-bit and 16-bit ppms and pgms. How would I go about this to prevent posterization? I would probably have to decompose the image(s) in some manner but the tricky thing is to have a representation on which CLAHE could work.
Thoughts?
