Normalize (modified) probability images
Description
Probability image lists should sum to one at every voxel. Smoothing or other
common operations may break this constraint. This function allows one to
easily ensure a list of proability images sums to one everywhere. It also
allows one prioritize specific images in the probability set such that its
probability is maintained while others are normalized with respect to the
prioritized value. Will also set values less than zero, to zero.
Usage
renormalizeProbabilityImages(probs, mask, k = NA)
Arguments
probs
list of images
mask
image
k
which image, if any, to prioritize
Value
list is output
Author(s)

Examples
mat <- t(matrix(rnorm(4000), ncol = 10))
mask <- makeImage(c(20, 20), 1)
plist <- matrixToImages(mat, mask)
rplist <- renormalizeProbabilityImages(plist, mask)
rplist2 <- renormalizeProbabilityImages(plist, mask, 2)
