Integrate vector field

Description

Utility function to integrate a vector field and create a deformation field.

Usage

integrateVectorField(
  referenceImage,
  vectorFieldFileName,
  deformationFieldFileName,
  lowerTime = 0,
  upperTime = 1,
  deltaTime = 0.01
)

Arguments

referenceImage	defines the image domain
vectorFieldFileName	the vector field exists on disk.
deformationFieldFileName	the deformation field output file name.
lowerTime	the starting time, usually zero for forward transformation and one for the inverse transformation.
upperTime	the ending time, usually one for forward transformation and zero for the inverse transformation.
deltaTime	the integration time step
