Color and Contrast Enhancement by Controlled Piecewise Affine Histogram Equalization
This paper presents a simple contrast enhancement algorithm based on histogram equalization (HE). The proposed algorithm performs a piecewise affine transform of the intensity levels of a digital image such that the new cumulative distribution function will be approximately uniform (as with HE), but...
