histeq can return a 1-by-256 vector that shows, for each possible input value, the resulting output value. (The values in this vector are in the range [0,1], regardless of the class of the input image.)

Use the default behavior of the histogram equalization function, histeq. The default target histogram is a flat histogram with 64 bins. Display the contrast-adjusted image and its new …

Histogram equalization is a method in image processing of contrast adjustment using the image's histogram. Histograms of an image before and after equalization.
