compute_mask(img_itk: Image) → Image

Compute the mask for the input image using the provided mask function.

Parameters:

img_itk (SimpleITK.Image) – The input image in SimpleITK format.

Returns:

The computed mask.

Return type:

SimpleITK.Image

correct(input_img_path: str | Path, output_img_path: str | Path) → None

Correct the bias field of the input image using SimpleITK.

Parameters:

• input_img_path (Union[str, Path]) – Path to the input image.

• output_img_path (Union[str, Path]) – Path where the corrected image will be saved.

Returns:

None
