randomANTsTransformation: random transformation matrix

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

random transformation matrix

Description

generates a random transformation matrix in ants style. takes an initial transformation, its parameters and a seed that allows repeatability.

Usage

randomANTsTransformation(
  loctx,
  transformType = c("Rigid", "Affine", "ScaleShear"),
  sdAffine,
  idparams,
  fixParams,
  seeder,
  idim
)

Arguments

loctx	initial affine transformation to modify
transformType	one of Rigid, Affine and ScaleShear
sdAffine	standard deviation parameter e.g. 0.15
idparams	identity parameters
fixParams	fixed parameters for ANTs or ITK transformation
seeder	random seed
idim	spatial dimension of transformation

Value

the input transformation matrix with parameters generated randomly
