transform an image by a random matrix

generates a random transformation matrix and its application to an image

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
