GaussSmoothArray: GaussSmoothArray

In TCIU: Spacekime Analytics, Time Complexity and Inferential Uncertainty

GaussSmoothArray

Description

An internal function named GaussSmoothArray. Original from AnalyzeFMRI package

Usage

GaussSmoothArray(
  x,
  voxdim = c(1, 1, 1),
  ksize = 5,
  sigma = diag(3, 3),
  mask = NULL,
  var.norm = FALSE
)

Arguments

x	The array to be smoothed.
voxdim	The dimensions of the volume elements (voxel) that make up the array.
ksize	The dimensions (in number of voxels) of the 3D discrete smoothing kernel used to smooth the array.
sigma	The covariance matrix of the 3D Gaussian smoothing kernel. This matrix doesn't have to be non-singular; zero on the diagonal of sigma indicate no smoothing in that direction.
mask	A 3D 0-1 mask that delimits where the smoothing occurs.
var.norm	Logical flag indicating whether to normalize the variance of the smoothed array.

Value

an array with the size of parameter x
