GrayscaleFillHoleImageFilter

Link to code

Bases: SEMLikeCommandLine

Wrapped executable: GrayscaleFillHoleImageFilter.

title: Grayscale Fill Hole Image Filter

category: Filtering.Morphology

description: GrayscaleFillholeImageFilter fills holes in a grayscale image. Holes are local minima in the grayscale topography that are not connected to boundaries of the image. Gray level values adjacent to a hole are extrapolated across the hole.

This filter is used to smooth over local minima without affecting the values of local maxima. If you take the difference between the output of this filter and the original image (and perhaps threshold the difference above a small value), you’ll obtain a map of the local minima.

This filter uses the itkGrayscaleGeodesicErodeImageFilter. It provides its own input as the “mask” input to the geodesic erosion. The “marker” image for the geodesic erosion is constructed such that boundary pixels match the boundary pixels of the input image and the interior pixels are set to the maximum pixel value in the input image.

Geodesic morphology and the Fillhole algorithm is described in Chapter 6 of Pierre Soille’s book “Morphological Image Analysis: Principles and Applications”, Second Edition, Springer, 2003.

A companion filter, Grayscale Grind Peak, removes peaks in grayscale images.

Optional Inputs:

  • args (a string) – Additional parameters to the command. Maps to a command-line argument: %s.

  • environ (a dictionary with keys which are a bytes or None or a value of class ‘str’ and with values which are a bytes or None or a value of class ‘str’) – Environment variables. (Nipype default value: {})

  • inputVolume (a pathlike object or string representing an existing file) – Input volume to be filtered. Maps to a command-line argument: %s (position: -2).

  • outputVolume (a boolean or a pathlike object or string representing a file) – Output filtered. Maps to a command-line argument: %s (position: -1).

Outputs:

outputVolume (a pathlike object or string representing an existing file) – Output filtered.

description: GrayscaleGrindPeakImageFilter removes peaks in a grayscale image. Peaks are local maxima in the grayscale topography that are not connected to boundaries of the image. Gray level values adjacent to a peak are extrapolated through the peak.

This filter is used to smooth over local maxima without affecting the values of local minima. If you take the difference between the output of this filter and the original image (and perhaps threshold the difference above a small value), you’ll obtain a map of the local maxima.

This filter uses the GrayscaleGeodesicDilateImageFilter. It provides its own input as the “mask” input to the geodesic erosion. The “marker” image for the geodesic erosion is constructed such that boundary pixels match the boundary pixels of the input image and the interior pixels are set to the minimum pixel value in the input image.

This filter is the dual to the GrayscaleFillholeImageFilter which implements the Fillhole algorithm. Since it is a dual, it is somewhat superfluous but is provided as a convenience.

Geodesic morphology and the Fillhole algorithm is described in Chapter 6 of Pierre Soille’s book “Morphological Image Analysis: Principles and Applications”, Second Edition, Springer, 2003.
