Original Abstract

This paper describes automatic and fast skull segmentation of head X-ray computed tomog-raphy (X-ray CT) images. Acquired data suffers from salient stair-step artifact which is corrected by registration using combination of phase correlation and gradient descent optimization methods. Skull segmentation is performed in the two steps, the first is segmentation of cortical bones by means of simple thresholding, and the second is classification of trabecular bones utilize information about shape of local histograms.
