Histogram Equalization

Histogram equalization capabilities in GIL are demonstrated by the program histogram_equalization, compiled from the sources example/histogram_equalization.cpp.

Synopsis

histogram_equalization expects to find an image called test_adaptive.png in the current directory, and produces an image in return, where the equalization have been applied: histogram_gray_equalized.png.

Specific requirements

The PNG library installed and configured.

Execution requirements
