pxsearch - Search image neighborhoods for pixels.

       CMTK  is  developed  with support from the NIAAA under Grant AA021697, National Consortium on Alcohol and
       Neurodevelopment in Adolescence (N-CANDA): Data Integration Component. From April 2009 through  September
       2011, CMTK development and maintenance was supported by the NIBIB under Grant EB008381.

       This  tool  reads  an  image  file,  as well as a list of pixel coordinates from standard input. For each
       pixel, a local neighbourhood  in the image is searched for the maximum value. The location of the maximum
       is then written to standard output.

GlobalToolkitOptions(thesearesharedbyallCMTKtools)--help
            Write list of basic command line options to standard output.

       --help-all
            Write complete list of basic and advanced command line options to standard output.

       --wiki
            Write list of command line options to standard output in MediaWiki markup.

       --man
            Write man page source in 'nroff' markup to standard output.

       --version
            Write toolkit version to standard output.

       --echo
            Write the current command line to standard output.

       --verbose-level<integer>
            Set verbosity level.

       --verbose, -v
            Increment verbosity level by 1 (deprecated; supported for backward compatibility).

       --threads<integer>
            Set maximum number of parallel threads (for POSIX threads and OpenMP).

   MainOptions--input-coordinates
            Coordinate  specification  mode  for  program  input.   Supported  values:  "absolute",   "indexed",
            "relative", "physical", where the default is "absolute", or use one of the following:

            --absolute
                 Use  absolute volume coordinates. For each dimension, the valid range is [0,FOV].  [Thisisthedefault]--indexed
                 Use grid indexes to  specify  coordinates.  For  each  dimension,  the  valid  value  range  is
                 [0,Dims-1].

            --relative
                 Use relative volume coordinates. For each dimension, the valid range is [0,1].

            --physical
                 Use  physical volume coordinates. Each given location is transformed into image coordinates via
                 the inverse of the images's index-to-physical space matrix.

       --output-coordinates
            Coordinate  specification  mode  for  program  output.   Supported  values:  "absolute",  "indexed",
            "relative", "physical", where the default is "absolute", or use one of the following:

            --absolute
                 Use  absolute volume coordinates. For each dimension, the valid range is [0,FOV].  [Thisisthedefault]--indexed
                 Use grid indexes to  specify  coordinates.  For  each  dimension,  the  valid  value  range  is
                 [0,Dims-1].

            --relative
                 Use relative volume coordinates. For each dimension, the valid range is [0,1].

            --physical
                 Use  physical volume coordinates. Each given location is transformed into image coordinates via
                 the inverse of the images's index-to-physical space matrix.

       --radius<string>
            Radius of the search region in pixels (specified either as triple "rX,rY,rZ",  or  a  single  value,
            "rXYZ").  The region searched is [2*rX+1,2*rY+1,2*rZ+1] pixels large, centered at the input location
            (but cropped at the image boundary).  [Default:1]--no-reorient
            Disable image reorientation into RAS alignment.
