itk_laplacian_sharpening
apply Laplacian sharpening filter to a volume
itk_laplacian_sharpening <input> <output> [options]
DESCRIPTION
itk_laplacian_sharpening applies a Laplacian sharpening filter to an image volume using the Insight Toolkit (ITK). The filter enhances edges and fine detail by subtracting a Laplacian-filtered version of the image from the original. This has the effect of amplifying high-frequency components, making transitions between different tissue types and structural boundaries more prominent.
Laplacian sharpening is useful as a preprocessing step to improve the contrast of boundaries before segmentation, registration, or visual inspection of medical images.
OPTIONS
--verbose- Print verbose information during processing.
--clobber- Overwrite the output file if it already exists.
EXAMPLES
Apply Laplacian sharpening to enhance edges:
itk_laplacian_sharpening input.mnc sharpened.mnc
Apply with verbose output and overwrite existing file:
itk_laplacian_sharpening input.mnc sharpened.mnc --verbose --clobber
