Pantex texture extraction application

Summary

New application for Pantex texture extraction. Closes #2022

Rationale

In otb there is ScalarImageToPanTexTextureFilter but there is no corresponding application (see #2022).

The filter is based on this paper : Pesaresi, Martino & Gerhardinger, A. & Kayitakire, Francois. (2008). A Robust Built-Up Area Presence Index by Anisotropic Rotation-Invariant Textural Measure. Selected Topics in Applied Earth Observations and Remote Sensing, IEEE Journal of. 1. 180 - 192. 10.1109/JSTARS.2008.2002869.

This Merge Request adds an application for PantexTextureExtraction. It has the following parameters :

• in : The input image to compute the features on
• channel : The selected channel index
• out : Output image containing the selected texture features
• min : Input image minimum. If this parameter is not set, the application will compute the minumum of the image.
• max : Input image maximum. If this parameter is not set, the application will compute the maximum of the image.
• sradx : Radius of the window on which textures are computed (x direction)
• srady : Radius of the window on which textures are computed (y direction)
• nbin : Number of bins per axis for histogram generation number of gray levels considered in the computation of co-occurance)

A test has been added for this application.

Note that there are two other application for texture extraction in OTB, HaralickTextureExtraction and SFSTextureExtraction
