Yang Ping Wang, Jian Wu Dang, Teng Sun, Xiao Gang Du · Advanced materials research · 2012
An algorithm of sequence medical images segmen- tation is proposed based on the combination of snakes algorithm and contour interpolation algorithm. Firstly, this algorithm uses snakes algorithm to segment the key layers in which target area change drastically. Then the algorithm calculates the position of reference points in the middle layers with the contour interpolation algorithm. Finally, snakes algorithm is applied again to segment the middle layers. Thus the segmentation of the sequence medical images are accomplished automatically. The experiments showed that the algorithm can obtain the boundary of the desired object from a sequence of medical images quickly and reliably.
