This tool corrects an image, already loaded in CaPTk, for magnetic field inhomogeneities using a non-parametric method [1].
REQUIREMENTS:
- An image loaded in CaPTk.
USAGE:
- Load an image in CaPTk.
- Launch the tool using the 'Preprocessing' -> 'BiasCorrection' menu option.
- Specify the output filename.
- Click on 'Save'.
- The output image is saved in the specified folder and automatically loaded in CaPTk.
