randomAffineImage: transform an image by a random matrix

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

transform an image by a random matrix

Description

generates a random transformation matrix and its application to an image

Usage

randomAffineImage(
  image,
  transformType = c("Rigid", "Affine", "ScaleShear"),
  sdAffine = 0.1,
  seeder,
  fixedParams,
  interpolation = "nearestNeighbor"
)

Arguments

image	input image to be transformed
transformType	one of Rigid, Affine and ScaleShear
sdAffine	standard deviation parameter e.g. 0.15
seeder	random seed
fixedParams	optional fixed parameters for ANTs or ITK transformation
interpolation	optional interpolation choice

Value

the transformed image and the transformation matrix
