DESCRIPTION

   COMMAND:
              antsAI

              Program to calculate the optimallinear transform parameters for aligning two images.

   OPTIONS:

       -d, --dimensionality 2/3

              This  option forces the image to be treated as a specified-dimensional image. If not specified, we
              try to infer the dimensionality from the input image.

       -m, --metric

              Mattes[fixedImage,movingImage,<numberOfBins=32>,<samplingStrategy={None,Regular,Random}>,<samplingPercentage=[0,1]>]
              GC[fixedImage,movingImage,<radius=NA>,<samplingStrategy={None,Regular,Random}>,<samplingPercentage=[0,1]>]
              MI[fixedImage,movingImage,<numberOfBins=32>,<samplingStrategy={None,Regular,Random}>,<samplingPercentage=[0,1]>]

              These image metrics are available: Mattes: Mattes mutual  information  (recommended),  GC:  global
              correlation, MI: joint histogram mutual information

       -t, --transform Rigid[gradientStep]
              Affine[gradientStep] Similarity[gradientStep] AlignGeometricCenters AlignCentersOfMass

              Several  transform  options  are  available. For the rigid, affine, and similarity transforms, the
              gradientStep characterizes the gradient descent optimization and is scaled appropriately for  each
              transform  using  the  shift  scales  estimator.  The  other  two transform types finds the simple
              translation transform which aligns the specified image feature. Note that the images are read from
              the similarity metric option although the metric isn't actually used.

       -p, --align-principal-axes

              Boolean indicating alignment by principal axes. Alternatively, one can align using blobs  (see  -b
              option).

       -b, --align-blobs numberOfBlobsToExtract
              [numberOfBlobsToExtract,<numberOfBlobsToMatch=numberOfBlobsToExtract>]

              Boolean  indicating  alignment by a set of blobs. Alternatively, one can align using blobs (see -p
              option).

       -s, --search-factor searchFactor
              [searchFactor=20,<arcFraction=1.0>]

              Incremental search factor (in degrees) which will sample the arc  fraction  around  the  principal
              axis or default axis.

       -g, --translation-search-grid [stepSize=25, AxBxC=0x0x0]

              Translation  search  grid  in  mm,  which  will  translate  the  moving image in each dimension in
              increments of the step size.

       -c, --convergence numberOfIterations
              [numberOfIterations,<convergenceThreshold=1e-6>,<convergenceWindowSize=10>]

              Number of iterations.

       -x, --masks fixedImageMask

              [fixedImageMask,movingImageMask]

              Image masks to limit voxels considered by the metric.

       -o, --output outputFileName

              Specify the output transform (output format an ITK .mat file).

       --random-seed seedValue

              Use a fixed seed for random number generation. The default  fixed  seed  is  overwritten  by  this
              value. The fixed seed can be any nonzero int value. If the specified seed is zero, the system time
              will be used.

       -v, --verbose (0)/1

              Verbose output.

       -h

              Print the help menu (short version).

       --help

              Print the help menu.  <VALUES>: 1
