Localized Adaptive Contrast Enhancement On Opencv And Python

I am trying to do image enhancement on different types of images. I have tried a lot of different methods but usually, it works only on one image but fails on a different image. I

Solution 1:

As fmw42 said, you potentially need to work on gray level images. So the suggestion was to convert to grayscale and invert as needed. I can suggest that you convert to Y Cb Br and apply on Y, and keep Cb Cr as is and see whether this works. This is the method I would use, say, to apply histogram equalization to a color image. CLAHE should do the trick for the gray level work.
