fitTransformToPairedPoints: Fit transform to points

In stnava/patchMatchR: Local patch matching with flexible transformation models in n-dimensional images

Fit transform to points

Description

This function will use either the Kabsch algorithm or a least squares fitting algorithm to match the pairs of points that the user provides. An antsr transform is returned.

Usage

fitTransformToPairedPoints(
  movingPoints,
  fixedPoints,
  transformType = "Affine",
  lambda = 1e-06,
  domainImage,
  numberOfFittingLevels = 4,
  meshSize = 1,
  dataWeights
)

Arguments

movingPoints	moving points matrix
fixedPoints	fixed points matrix
transformType	Rigid, Similarity, Affine and BSpline currently supported
lambda	ridge penalty in zero to one interval
domainImage	image defining the domain for deformation maps.
numberOfFittingLevels	integer specifying the number of fitting levels.
meshSize	vector defining the mesh size at the initial fitting level.
dataWeights	vector defining the individual weighting of the corresponding scattered data value. Default = NULL meaning all values are weighted the same. Currently, this is only relevant to BSpline fits but FIXME will be generalized.

Value

antsTransform that maps the moving image to the fixed image space. the inverse transform maps the moving points to the fixed space. Associated error is also returned.
