This function calculates information about a cuboidal region of an image, with a centre and a fixed voxel width.
createNeighbourhoodInfo(width, dim = 3, centre = rep(0, dim))createNeighbourhoodInfo returns a list with class
"neighbourhoodInfo" and elements
Copied from the width argument.
Copied from the dim argument.
Copied from the centre argument.
dim x width^dim matrix whose columns give
the locations of each point in the neighbourhood.
A square, symmetric matrix of inner products between every location in the neighbourhood and every other.
An integer voxel width. Must be odd.
An integer giving the dimensionality of the neighbourhood. Currently must be 3.
A numeric vector giving the centre voxel of the neighbourhood.
Must have exactly dim elements.
