&amp;lt;!-- ---------------------------- --&amp;gt;&lt;br /&gt;
This module can be used in order to compute bone morphometry features of an input image. The computation of the bone morphometry features is based on a binary segmentation of the whole image and it based on the itk remote module: itkBoneMorphometry [https://github.com/InsightSoftwareConsortium/ITKBoneMorphometry itkBoneMorphometry].&amp;lt;br&amp;gt;&lt;br /&gt;
The following Bone Morphompetry Features are computed: &lt;br /&gt;
* percent bone volume [BVTV]&lt;br /&gt;
* trabecular thickness [TbTh]&lt;br /&gt;
* trabecular separation [TbSp]&lt;br /&gt;
* trabecular number [TbN]&lt;br /&gt;
* Bone Surface to Bone Volume ratio [BSBV]&lt;br /&gt;
&lt;br /&gt;
