<DIV>Dear Luis</DIV> <DIV> </DIV> <DIV>Yesterday I send my question to you. But you reply me without any answer. </DIV> <DIV> </DIV> <DIV>I try to use the level set method to segment. Now I have obtained initial surface. For quicken the curve evolution‎, I want to employ narrow band method to evolve the surface. I want to know:<BR> </DIV> <DIV>1. What function(filter) is able to construct a narrow band around<BR>surface to be evolved.</DIV> <DIV>2. What is the stopping criterion for evolution? <BR> <BR>Though I know of itkNarrowBandLevelSetImageFilter, itkNarroBandCurvesLevelSetImageFilter,<BR>itkNarrowBandThresholdSegmentationLevelSetImageFilter, I don’t know how to use these function. </DIV> <DIV> </DIV> <DIV>Moreover, would you like to tell me how to learn to use one function by explanation in Doxygen, because there aren’t application examples about most functions in ITK Software
Guide. <BR> <BR>Thank you for your help!<BR> <BR>Best wishes,<BR> <BR>Sin<BR></DIV><p>
