robust_window: Window image based on quantiles of Image

In neurobase: 'Neuroconductor' Base Package with Helper Functions for 'nifti' Objects

Window image based on quantiles of Image

Description

Takes an image, finds the quantiles given by probs, then sets values outside these values to other values, as determined by replace argument passed to to window_img

Usage

robust_window(img, non_zero = FALSE, probs = c(0, 0.999), ..., mask = NULL)

Arguments

img	object of class nifti
non_zero	Should zeroes be excluded from the calculation of quantiles?
probs	quantiles to constrain the image these define the window sent to window_img
...	additional arguments sent to window_img
mask	binary image to use to to calculate quantiles

Value

Object of class nifti with values outside quantiles replaced by values depending on replace argument passed to window_img
