[Insight-users] ThresholdSegmentationLevelSet

[Luis Ibanez]

Hi Zein,

The ThresholdSegmentationLevelSet example illustrates
how to use the ThresholdSegmentationLevelSetImageFilter.
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1ThresholdSegme=
ntationLevelSetFunction.html

This is a recently writen example, so it may still have
some tweaks on it.

This filter evolves a level set starting from a
binary mask (it is in some way the equivalent of a
deformable contour driven by the evolution of an
implicit function.


Here is a short description of how to use it:

1) Load a 3D Image by clicking on the "Load" button.
    (e.g. any of the BrainWeb images on the ftp
    site  ftp://public.kitware.com/pub/itk/Data/BrainWeb)

2) Create seeds for the binary mask:
    Display the image by clicking on the "Input Image" button.
    Once the image is displayed you can select slices and create
    seed points by clicking with the left mouse button on the
    image. Red points will be displayed on the selected points.


3) Run the filter by clicking on "Threshold Segmentation"
    (it will take about 10 seconds to run in one of the BrainWeb
    images)

4) When the filter is done, the "Display" button will turn
    green and you can click on it to display the result.
    The result of the evolved level set is displayed slice by
    slice in a viewer.

5) Visualization with VTK is under development on this
    example...


Please let us know if you have further questions,

   Thanks


    Luis
