Description

Face Removal Mask using "Quickshear Defacing for Neuroimages" (Schimke et al. 2011)

Usage

get_quickshear_mask(brain_mask, buffer = 10, verbose = TRUE)

quickshear_deface_image(
  file,
  brain_mask = NULL,
  buffer = 10,
  verbose = TRUE,
  ...
)

Arguments

brain_mask	Brain mask image. If NULL, then fslbet will be run
buffer	buffer to add to intercept for face mask equation
verbose	print diagnostic messages
file	input image - same orientation as brain mask
...	additional arguments passed to fslmask

Value

A binary image of the non-face areas

       res = quickshear_deface_image(file)
       brain_mask = fslbet(file) > 0
       mask = get_quickshear_mask(brain_mask)
       image = fslmask(file, mask)
