get_neighbors: Calculate Moments of Neighborhood

In neuroconductor-devel/ichseg: Intracerebral Hemorrhage Segmentation of X-Ray Computed Tomography (CT) Images

Description

This function calculates Local Moments (mean, standard deviation, skew) for an array.

Usage

get_neighbors(image, window = NULL, nvoxels = NULL, mask = NULL,
  rm.value = FALSE, check.wrap = TRUE, rep.value = 0, ...)

Arguments

image	input image
window	window (in width) for the neighborhood
nvoxels	window (in voxels) for the neighborhood 1 results in a 3x3 cube
mask	array or object of class nifti of same size as image
rm.value	remove the voxel itself before taking the moment
check.wrap	Logical - check wrapround and put rep.value in for the wrapped values
rep.value	Replace wrapped values (edge of image) to this value
...	Not used

Value

Array with same dimensions as image

Examples

x = array(rnorm(1000), dim=c(10, 10, 10))
neigh = get_neighbors(x, nvoxels = 1)
