Hi, all,<br><br>I am working the task of visualization of vessel segmentation right now.<br><br>I am not sure whether the problems are in the ITK code or in the VTK code, <br>but the problems occurs when adding vtk classes, so I post my problem here. <br>
<br>I chose itk::CurvesLevelSetImageFilter for segmentation and vtkContourFilter<br>for visualization. The pipeline are constructed based on the example code of <br>the level set image filter in the following directory:<br>
<br> InsightToolkit\Examples\Segmentation\itkCurvesLevelSetImageFilter.cxx<br><br>After doing some experiments with single piece of 2D images (in dicom format), <br>I modified the example code above to enable 3D reconstruction of the <br>
segmentation results. However, I received the following result in vtk's render <br>window:<br><br> <a href="http://i1238.photobucket.com/albums/ff483/cdfinder/result1.png">http://i1238.photobucket.com/albums/ff483/cdfinder/result1.png</a><br>
<br>The red blobs are generated in the approximity of the seeds "in" the region <br>of vessels and are supposed to be two test balloons. But they apparently <br>appear in the wrong position.<br><br>Could anyone give me some advice? <br>
