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.
