  1. Why don t we apply histogram equalization on each color channel separately to implement histogram equalization on color images?

Why don t we apply histogram equalization on each color channel separately to implement histogram equalization on color images?

Channel splitting and equalizing each channel separately is incorrect. Equalization involves intensity values of the image, not the color components. So for a simple RGB color image, histogram equalization cannot be applied directly on the channels.
