Local Histogram Equalization
===============================
============================
This examples enhances an image with low contrast, using a method called
*local histogram equalization*, which "spreads out the most frequent intensity
values" in an image .
The equalized image [1]_ has a roughly linear cumulative distribution function for each pixel neighborhood.
The local version [2]_ of the histogram equalization emphasized every local graylevel variations.
