| Abstract: | The narrow band level set method is a kind of technique which tracks the evolving interface.Its computation domain is set near the zero level set.The distant template method(DTM) is proposed and compared with the fast marching method(FFM) and fast sweep method on time complexity,the effects of the width and the number of points with zero level on the narrow band's construction.On the basis of analyzing FFM,a method with O(n) time complexity is given to construct the narrow band.The fast sweep method(FSM) is improved for the narrow band's construction.The simulation experiments of 2D image segmentation and 3D surface reconstruction demonstrate that the DTM can segment the images efficiently and FFM and FSM are suitable for 3D application such as surface reconstruction with level set method. |
