Pipeline for refining LR brain masks. (i) maps slice-by-slice the brain mask of every stack into the HR space using the motion parameters estimated during motion estimation. (ii) applies a voting strategy to obtain a unique HR brain mask. (iii) applies a Markov Random Field filter to obtain a coherent HR brain mask. (iv) maps the refined HR brain mask back to each slice of the stacks. Note that this has been simplified for illustration; there are usually more than one stack of slices with their corresponding masks in each direction.
