The level set filter evolves a PDE over time. The PDE solver framework does not take spacing into account. <br>The few ones that do have a UseImageSpacing ivar. I would recommend using the ResampleImageFilter to resample your image to isotropic spacing prior to using any of the level set filters.

Dear all,<br><br>In <a href="http://www.itk.org/Doxygen/html/classitk_1_1SegmentationLevelSetImageFilter.html">http://www.itk.org/Doxygen/html/classitk_1_1SegmentationLevelSetImageFilter.html</a><br>under "A NOTE ON DATA SPACING" it says "Input data with anisotropic
<br>spacing should be resampled to isotropic voxels for use in this<br>filter".<br><br>Is this still the case for all filters derived from the<br>itkSegmentationLevelSetImageFilter?<br><br>Thanks,<br>Charl<br>_______________________________________________
