===Module 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. A companion filter, Grayscale Fill Hole, fills
holes in grayscale images.

== Usage ==
GrayscaleGrindPeakImageFilter.exe
[--returnparameterfile
<std::string>]
[--processinformationaddress
<std::string>] [--xml] [--echo]
[--] [--version] [-h] <std::string>
<std::string>
Where:

--returnparameterfile <std::string>
Filename in which to write simple return parameters (int, float,
int-vector, etc.) as opposed to bulk return parameters (image,
geometry, transform, measurement, table).

--processinformationaddress <std::string>
Address of a structure to store process information (progress, abort,
etc.). (default: 0)

--xml
Produce xml description of command line arguments (default: 0)

--echo
Echo the command line arguments (default: 0)

--, --ignore_rest
Ignores the rest of the labeled arguments following this flag.

--version
Displays version information and exits.

-h, --help
Displays usage information and exits.

<std::string>
(required) Input volume to be filtered

<std::string>
(required) Output filtered
