<div style="direction:ltr;font-size:10pt;font-family:Tahoma">Dear ITK users,
<div><br>
</div>
<div>I have two questions on Level Sets in ITK. </div>
<div><br>
</div>
<div>Is there a Level Sets model that is triangulated, i.e.: produces a watertight polygonalization of the zero-level isosurface? Is there a way to produce this watertight triangulation? I know that VTK has Marching Cubes, but I have misgivings about this method
producing a watertight result. </div>
<div><br>
</div>
<div>Second, I would like to use an example with phantom images that are narrow structures, similar to the Circle of Willis, but in 2D, and I would like to have a recommendation for working example code that I can use with this. I have tried ShapeDetectionLevelSetSegmentation,
but I find this example produces a constant speed term, as opposed to a speed term that halts the model on high-gradient areas of the image. </div>
<div><br>
</div>
<div>Please advise. </div>
<div><br>
</div>
<div>Thanks for your kind consideration.</div>
