HISTOGRAM EQUALIZATION


Histogram / Equalization

Histogram equalization is an algorithm that changes the distribution of brightness levels in an image so that the brightness levels occur at approximately the same frequency. For images with a finite number of pixels, this goal can only be approached. Equalization allows hard-to-detect details in an overall high-contrast image to be highlighted with low contrast.
