NAME

       geomatch  -  Check  whether  the  geometries  (e.g., grid dimensions, pixel sizes, spatial
       coordinates) or two or more images match.

SYNOPSIS

       geomatch ImagePaths

DESCRIPTION

       This tool reads two or more images and tests whether their grid dimensions,  pixel  sizes,
       and  image-to-space  transformations  match.  Optionally,  all  images are reoriented into
       standard orientation before performing the test. If all images  match,  the  tool  returns
       with exit code 0, otherwise it returns with exit code 2. In case of an error (e.g., one of
       the images can not be read), the exit code is 1.

OPTIONS

   Global Toolkit Options (these are shared by all CMTK tools)
       --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).

   Input Options

   Image Comparison Options
       --no-check-xforms
            Do not check transformation matrices.

       --no-check-pixels
            Do not check pixelsizes.

       --tolerance <double>
            Numerical tolerance  for  floating  point  comparisons  of  transformation  matrices.
            [Default: 1e-06]

       --tolerance-xlate <double>
            Numerical tolerance for floating point comparisons of the translational components of
            the transformation matrices.  [Default: 0.001]
