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 canpsilat be preserved in the whole deformation region. In order to solve the problem, a more reasonable modified Demons algorithm is proposed,...
In this paper, we propose a new segmentation approach based on level set techniques to segment the brain MR images. We adopt a new binary regional term based on the fuzzy information of the image in the new algorithm, which can inflate or contract the evolving curves automatically without predefined the evolving directions during the initialization phase. The algorithm can segment brain tissues from...
Based on the concept of the fractional lower order stationary process, this paper provides and proves the properties of the fractional lower order covariance (FLOC) systematically, and presents the applications of the FLOC in the latency change detection of evoked potentials. The analysis and experiments demonstrate that the FLOC based algorithm has better performances than those of the second order...
