Denoise-SUSAN (ITK filter)

This tool smooths an image already loaded in CaPTk, to remove any high frequency intensity variations (i.e., noise), using the SUSAN algorithm [1].

REQUIREMENTS:

1. An image loaded in CaPTk.

USAGE:

1. Load an image in CaPTk.
2. Launch the tool using the 'Preprocessing' -> 'Denoise-SUSAN' menu option.
3. Specify the output filename.
4. Click on 'Save'.
5. The output image is saved in the specified folder and automatically loaded in CaPTk.
6. This can also be used from the command line:

   ${CaPTk_InstallDir}/bin/Preprocessing.exe -i C:/test/image.nii.gz -o C:/test/image_smooth.nii.gz -ss
