My first question is if it is in general better to apply the contract enhancement techniques like imadjust(), histeq() in HSV (on V) or LAB (on L).
Besides this, I have a question about the italic part of the definition of imadjust(). Can someone explain this to me with a visualization or something like that?
- imadjust increases the contrast of the image by mapping the values of the input intensity image to new values such that, by default, 1% of the data is saturated at low and high intensities of the input data.
Are there besides imadjust(), histeq(), adapthisteq() other contrast enhancement techniques I could try? Imadjust() seems to have the best effect, however I would expect histeq() would have the best effect, because it ensures a uniform histogram in stead of the tops that are still seen at imadjust().
