&amp;lt;!-- ---------------------------- --&amp;gt;&lt;br /&gt;
This module can be used in order to compute co-ocurence texture features over the input image. The computation of the run length features is based on the grey level Co-ocurence matrix (GLCM) computed with [https://itk.org/Doxygen/html/classitk_1_1Statistics_1_1ScalarImageToTextureFeaturesFilter.html itk::itkScalarImageToTextureFeaturesFilter].&amp;lt;br&amp;gt;&lt;br /&gt;
The GLCM matrix describes the texture of the whole image, it is then used to compute the following run length texture features: &lt;br /&gt;
* Energy&lt;br /&gt;
* Entropy&lt;br /&gt;
* Correlation&lt;br /&gt;
* Inverse difference moment&lt;br /&gt;
* Inertia&lt;br /&gt;
* Cluster shade&lt;br /&gt;
* Cluster prominence&lt;br /&gt;
* Haralick correlation&lt;br /&gt;
&lt;br /&gt;
