Abstract:In this paper we present HEAD, the Human Encephalon Automatic
Delimiter, a new and efficient method for skull-stripping in
T1-weighted MRI that combines an unique histogram analysis with
binary mathematical morphology. In our experiments we use real
images with highly variable noise ratios and intensity
non-uniformity. We evaluate our results based on manually generated
true masks and the well known Jaccard metric, achieving accuracy
close to 99%. We compare our method with the popular Brain Extractor
Surface algorithm (BSE), which in the same experiments achieved less
than 95% of accuracy.
