       iMath - part of ANTS registration suite

SYNOPSIS

       iMath ImageDimension <OutputImage.ext> [operations and inputs] <Image1.ext> <Image2.ext>

DESCRIPTION

       Usage Information

              ImageDimension: 2 or 3 (for 2 or 3 dimensional operations).  ImageDimension: 4 (for
              operations on 4D file,  e.g.  time-series  data).   Operator:  See  list  of  valid
              operators below.

       Mask and Label set operations -----------------------------

       GetLargestComponent
              : Get the single largest labeled object in an image

       Usage  : GetLargestComponent InputImage.ext {MinObjectSize=50}

       Morphological operations ----------------------------- Possible operations are:

              MC = Closing MD = Dilation ME = Erosion MO = Opening

   Possible values for the shape parameter and associated settings are:
              ball  {RadiusIsParmetric=0}  box cross annulus {RadiusIsParametric=0} {Thickness=1}
              {IncludeCenter=0} polygon {Lines=3}

       Description of Parameters

              RadiusIsParametric: The 'ball' and 'annulus' structuring elements have an  optional
              flag  called  'radiusIsParametric' (off by default). Setting this flag to true will
              use the parametric definition of the object and will generate structuring  elements
              with  more  accurate  areas,  which  can be especially important when morphological
              operations are intended to remove or retain objects of particular sizes.  When  the
              mode  is  turned  off (default), the radius is the same, but the object diameter is
              set to (radius*2)+1, which is the  size  of  the  neighborhood  region.  Thus,  the
              original ball and annulus structuring elements have a systematic bias in the radius
              of +0.5 voxels in each dimension relative  to  the  parametric  definition  of  the
              radius.  Thus,  we  recommend  turning  this  mode on for more accurate structuring
              elements, but this mode is turned off by default for backward compatibility.

              Usage   :   Operation   InputImage.ext   {Radius=1}    {ObjectValue=1}    {Shape=1}
              {RadiusIsParametric=0 or Lines=3} {Thickness=1} {IncludeCenter=0}
