randomMask: Get a random mask

Description

Get a mask with a specific number of voxels randomly distributed on the input image/mask

Usage

randomMask(img, nsamples, perLabel = F)

Arguments

img
an antsImage, either continuous or mask-like. This will define the space where to sample voxels from. If this image is continous (i.e., a T1), voxels will be sampled from all nonzero voxels.
nsamples
the number of random voxels to select from
perLabel
logical, if true the input image must be multi-label and the the output will have nsamples from each label (i.e., 200 samples from each label)

Value

binary antsImage with random voxels set to 1

Examples

Run this code

img<-antsImageRead( getANTsRData("r16"))
randmask<-randomMask(img,200)
