Long Description

Structural Feature Set [1] are based on the histograms of the pixels in multiple directions of the image. The SFSTextureExtraction application computes the 6 following features: SFS'Length, SFS'Width, SFS'PSI, SFS'W-Mean, SFS'Ratio and SFS'SD (Standard Deviation). The texture indices are computed from the neighborhood of each pixel. It is possible to change the length of the calculation line (spatial threshold), as well as the maximum difference between a pixel of the line and the pixel at the center of the neighborhood (spectral threshold) [2].

Parameters

Input Image (in): The input image to compute the features on.
Selected Channel (channel): The selected channel index
Available RAM (Mb) (ram): Available memory for processing (in MB)
Texture feature parameters (parameters): This group of parameters allows one 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.
- Spectral Threshold (parameters.spethre): Spectral Threshold
- Spatial Threshold (parameters.spathre): Spatial Threshold
- Number of Direction (parameters.nbdir): Number of Direction
- Alpha (parameters.alpha): Alpha
- Ratio Maximum Consideration Number (parameters.maxcons): Ratio Maximum Consideration Number

Feature Output Image (out): Output image containing the SFS texture features.
