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 MI[fixedImage,movingImage,<numberOfBins=32>,<samplingStrategy={None,Regu‐ lar,Random}>,<samplingPercentage=[0,1]>] Mattes[fixedImage,movingImage,<numberOfBins=32>,<samplingStrategy={None,Regu‐ lar,Random}>,<samplingPercentage=[0,1]>] GC[fixedImage,movingIm‐ age,<radius=NA>,<samplingStrategy={None,Regular,Random}>,<samplingPercent‐ age=[0,1]>] These image metrics are available: MI: joint histogram and Mattes: mutual informa‐ tion and GC: global correlation. -t, --transform Rigid[gradientStep] Affine[gradientStep] Similarity[gradientStep] Several transform options are available. The gradientStep or learningRate charac‐ terizes the gradient descent optimization and is scaled appropriately for each transform using the shift scales estimator. -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,<arcFraction=1.0>] Incremental search factor (in degrees) which will sample the arc fraction around the principal axis or default axis. -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). -v, --verbose (0)/1 Verbose output. -h Print the help menu (short version). --help Print the help menu. <VALUES>: 1
