abpN4: MR image bias correction based on the N4 algorithm.
Description
Truncate outlier intensities and bias correct with the N4 algorithm.
Usage
abpN4(img, intensityTruncation = c(0.025, 0.975, 256), mask = NA, usen3 = FALSE)
Arguments
img
image to be bias corrected
intensityTruncation
quantiles for image truncation.
mask
optional antsImage mask
usen3
Use N3 algorithm instead of N4
Value
outputs a bias corrected image. 1 indicates failure.
Examples
Run this code
img <- antsImageRead(getANTsRData("r16"))
img2 <- abpN4( img )
