Histogram Algorithms
Dietrich W. R. Paulus, Joachim Hornegger · 1997
Histograms were already introduced in Chapter 8. In the following sections we will define several useful image preprocessing steps using histograms. Each algorithm can easily be implemented and tested applying the implementation of a class Histogram. In addition to standard methods working on gray-level images, we also introduce two color image algorithms based on histograms.
