histogramMatchImage2: Transform image intensities based on histogram mapping.

In stnava/ANTsR: ANTs in R: Quantification Tools for Biomedical Images

Transform image intensities based on histogram mapping.

Description

Apply B-spline 1-D maps to an input image for intensity warping.

Usage

histogramMatchImage2(
  sourceImage,
  referenceImage,
  sourceMask = NULL,
  referenceMask = NULL,
  matchPoints = 64,
  transformDomainSize = 255
)

Arguments

sourceImage	source image.
referenceImage	reference image.
sourceMask	source mask.
referenceMask	reference mask.
matchPoints	parametric points at which the intensity transform displacements are specified between [0, 1]. Alternatively, a single number can be given and the sequence is linearly spaced in [0, 1].
transformDomainSize	Defines the sampling resolution of the B-spline warping.

Value

warped intensity image
