\defgroup group_imgproc_retinex Retinex
Enhance the contrast of a color image using the Retinex technique, based on the Retinex ImageJ plugin:
<blockquote>
Retinex filtering is based on Land's theory of image perception, proposed to explain the perceived colour constancy
of objects under varying illumination conditions. Several approaches exist to implement the retinex principles,
among these the multiscale retinex with colour restoration algorithm (MSRCR) combines colour constancy
with local contrast enhancement so images are rendered similarly to how human vision is believed to operate.
</blockquote>
This method is based on the <a href="http://imagej.net/Retinex">Retinex ImageJ</a> plugin written by Francisco Jiménez Hernández,
which is a modified implementation of the Retinex filter from the <a href="https://docs.gimp.org/en/plug-in-retinex.html">GIMP package</a>
by Fabien Pelisson.
