itk_fill_hole

apply hole-filling operation to a volume

itk_fill_hole <input> <output> [options]

DESCRIPTION

itk_fill_hole fills holes in a grayscale image volume using the ITK grayscale fill-hole filter. A “hole” is defined as a connected region of dark voxels that is completely surrounded by brighter voxels. The filter raises the intensity of hole regions to match the surrounding level, effectively filling in valleys in the intensity landscape.

This operation is useful for correcting intensity inhomogeneities, removing dark artefacts inside structures, and preparing volumes for subsequent segmentation or thresholding steps.

OPTIONS

--verbose

Print verbose information during processing.

--clobber

Overwrite the output file if it already exists.

EXAMPLES

Fill holes in a grayscale volume:

itk_fill_hole input.mnc filled.mnc

Fill holes with verbose output, overwriting existing file:

itk_fill_hole input.mnc filled.mnc --verbose --clobber
