Adjustments : Histogram Equalization

Histogram Equalization

This is a method of contrast adjustment that uses the image's histogram. It works by distributing intensities on the histogram to allow for areas of lower local contrast to gain a higher contrast without affecting the global contrast. Histogram equalization accomplishes this by effectively spreading out the most frequent intensity values. Chasys Draw IES implements histogram equalization using the cumulative distribution factor of the luminance channel on a HSL color-space.
