Input Image The input image to compute the features on.
Selected Channel The selected channel index
Available RAM (Mb) Available memory for processing (in MB)
Texture feature parameters This group of parameters allows to define SFS texture parameters. The available texture features are SFS’Length, SFS’Width, SFS’PSI, SFS’W-Mean, SFS’Ratio and SFS’SD. They are provided in this exact order in the output image.
Feature Output Image Output image containing the SFS texture features.
