Module Description

This module can be used in order to compute run length texture feature maps of an input image. The computation of the run length features is based on the grey level run length matrix (GLRLM) computed with itk::itkRunLengthTextureFeaturesImageFilter for each pixel’s neighborhood.
The GLRLM matrix describes each neighborhood local texture, it is then used to compute the following run length texture features:

• short run emphasis
• long run emphasis
• grey level non uniformity
• run length non uniformity
• low grey level run emphasis
• high grey level run emphasis
• short run low grey level emphasis
• short run high grey level emphasis
• long run low grey level emphasis
• long run high grey level emphasis

Use Cases

Inputs: Input volume [index: 0] : Input Volume Output volume [index: 1] : Output diffusion-weighted volume where the 10 feature maps will be stored Input mask [-s --inputMask] (None) : A mask defining the region over which texture features will be calculated Inside Mask Value [-i --inputMask] (1) : The pixel value that defines the ”inside” of the mask Number of Intensity bins [-b --binNumber] (10) : The number of intensity bins Pixel Intensity Min [-p --pixelIntensityMin] (0) : Minnimum of the pixel intensity range over which the features will be calculated Pixel Intensity Max [-P --pixelIntensityMax] (4000) : Maximum of the pixel intensity range over which the features will be calculated Distance Min [-d --distanceMin] (0.0) : Minnimum of the distance range over which the features will be calculated Distance Max [-D --distanceMax] (1.0) : Maximum of the distance range over which the features will be calculated
