... histogram equalization is performed in order to visually emphasize various subtle features on the map... Histogram equalization takes a raster of intensities, plots the number of times each intensity occurs, and then creates a mapping from the original intensities to a new set so that each intensity level occurs with approximately equal frequency. 4, record 1, English, - histogram%20equalization
