is there an example about itkNarrowBandCurvesLevelSetImageFilter?

Hello,everyone:
   I want to employ itkNarrowBandCurvesLevelSetImageFilter to relize the Narrow Band Level Set
Segmentation , but I do not know how to use this class. Is there an EXAMPLE showing how to realize
segmentation employing itkNarrowBandCurvesLevelSetImageFitler? Is the pipeline of the
segmentation employing itkNarrowBandCurvesLevelSetImageFilter as same as the pipeline of the
segmentation using itkShapeDetectionImageFiler?

Thanks in advance!

outer surface extraction

Hi All,

I am trying to get the 3D outer surface of the head from MRI scans.

I have a 3D (very noisy) image of the head.

To do so we tried 3 approaches:

1. Using VTK we cleaned the data and "shot" rays during bounding box and
saved the closest intersection points.
   The cloud of points look pretty good. But we need a "good"
triangulation for curvature calculation. (Delauny is not good for that
for example).

2. Using MATLAB we segmented the outer surface slice by slice
(automatic). However it is important to do this on 3D data since the
result is noisy in the "z" direction (we smoothed it and it is till not
good enough).

3. Therefore we are seeking for a 3D segmentation approach; threshold
level set as Luis suggested us seems good. 

My questions are:

1. Does someone know a consistent triangulation method/implementation?

2. Does someone have a 3D segmentation of the outer surface examples
(with complex objects and noisy data)?

Thank you,

(and sory for the long letter)

      Ruby
