Abstract
Image registration plays an important role in medical image processing. In this paper, a topology preservation image registration algorithm based on modified Spring-Mass model is presented. The image registration problem is transferred to the problem of mechanics balance, by defining the external force as the Gateaux derivate on mass displace field of template and source image' SSD measure. A scheme modifying the mass's velocity directly is used for the topology preservation of spring-mass model s evolving. Also, Multi-layers scheme is used for more efficient evolving. A series of experimental results are offered to show the useful of the method.
