getNeighborhoodAtVoxel: Get a hypercube neighborhood at a voxel

Description

Get the values in a local neighborhood of an antsImage.

Usage

getNeighborhoodAtVoxel(image, center, radius, physical.coordinates = FALSE)

Arguments

image

Image object of S4 class antsImage to get values from.

center

array of indices for neighborhood center

radius

array of values for neighborhood radius (in voxels)

physical.coordinates

a logical indicating if voxel indices and offsets should be in voxel or physical coordinates

Value

a list

• valuesnumeric vector of values

• indicesmatrix providing the coordinates for each value

Examples

# NOT RUN {
img<-makeImage(c(10,10),rnorm(100))
center <- dim(img)/2
radius <- rep(3,2)
nhlist<-getNeighborhoodAtVoxel(img,center,radius)
# }
