摘要：In this paper the force formulation based on optical flow of the Demons non-rigid registration algorithm is analyzed. It is indicated that the force formulation has some limitations in certain circumstances, which may be the reason that the topology structure can't be preserved in the whole deformation region. In order to solve the problem, a more reasonable modified Demons algorithm is proposed, which is approved by the experiment results.
