Hi Mashid,<br><br>The code in question was actually modified and moved to the ITK Review directory. When you compile ITK, please turn on the USE_REVIEW option in the CMake configuration.<br><br>The level-set filters in the Review directory are divided into two parts: 1. Solver filters and 2. Difference function filters.<br>
<br>Please see the implementation of the itkScalarChanAndVeseDenseLevelSetImageFilter and itkScalarChanAndVeseLevelSetFunction for an example to implement your own new function.<br><br><br>Kishore<br><br><br><div class="gmail_quote">

<div>Dear itk users,</div>
<div> </div>
<div>I am recently working on Level Set Methods and Prior Shape based models. I downloaded itk code " Active Contour Without Edges". As my understandings the regions information are computed in RegionBasedLevelSetFunction and the core filter is <span lang="">DenseMultiphaseLevelSetImageFilter. I can not see how this filter makes connection with RegionBasedLevelSetFunction to calculate speed. It seems that function CalculateSpeedImage() should be called to achieve GenerateSpeedImage() in <span lang="">DenseMultiphaseSegmentationLevelSetImageFilter. why RegionBasedLevelSetFunction does not implement function CalculatedSpeedImage(). How RegionBasedLevelSetFunction is used in <span lang="">DenseMultiphaseLevelSetImageFilter.</span></span></span></div>
