staple_bin_img: Run STAPLE on a set of nifti images

In neuroconductor-devel/stapler: Simultaneous Truth and Performance Level Estimation

Description

Run STAPLE on a set of nifti images

Usage

staple_bin_img(x, set_orient = FALSE, verbose = TRUE, ...)

staple_multi_img(x, set_orient = FALSE, verbose = TRUE, ...)

Arguments

x	Character vector of filenames or list of arrays/images
set_orient	Should the orientation be set to the same if the images are niftiImages
verbose	print diagnostic messages
...	Additional arguments to staple_bin_mat

Value

A list similar to staple_bin_mat, but has a resulting image

Examples

n = 5
r = 1000
x = lapply(seq(n), function(i) {
   x = rbinom(n = r, size = 1, prob = 0.5)
   array(x, dim = c(10,10, 10))
 })
staple_out = staple_bin_img(x, set_orient = FALSE)
res = staple(x)
testthat::expect_equal(staple_out$sensitivity,
res$sensitivity)

x = lapply(x, RNifti::asNifti, internal = FALSE)
staple_img_out = staple_bin_img(x, set_orient = FALSE)
testthat::expect_equal(staple_out$sensitivity,
staple_img_out$sensitivity)
n = 5
r = 1000
x = lapply(seq(n), function(i) {
   x = rbinom(n = r, size = 5, prob = 0.5)
   array(x, dim = c(10,10, 10))
 })
staple_out = staple_multi_img(x, set_orient = FALSE)
