normalizeHM: Histogram matching intensity normalization.

In neuroconductor-releases/RAVEL: Removal of Artificial Voxel Effect by Linear Regression

Description

Histogram mathing intensity normalization.

Usage

normalizeHM(input.files, output.files = NULL, brain.mask = NULL,
  type = c("T1", "T2", "FLAIR", "PD"), writeToDisk = FALSE,
  returnMatrix = TRUE, verbose = TRUE)

Arguments

input.files	Vector of filenames for the input images. Must be NIfTI files.
output.files	Optional vector of filenames for the output images. By default, will be the input.files with suffix "WS".
brain.mask	Filename for the brain binary mask specifying the template space brain. Must be a NIfTI file.
type	What modality is used? Should be one of T1, T2, FLAIR or PD.
writeToDisk	Should the normalized scans be saved to the disk?
returnMatrix	Should the matrix of normalized intensities be returned?
verbose	Should messages be printed?

Value

if returnMatrix is FALSE, no value returned, but Histogram-matching-normalized images are saved. If returnMatrix is TRUE, Histogram-matching-normalized images are saved and a matrix of normalized intensities is returned.
