[Insight-users] Runtime memory error in Fast marching Segmentation level set program

[Luis Ibanez]

Hi Shaohua,


It looks like you are loading 2D images.

These demo applications

  - FastMarchingLevelSet
  - ShapeDetectionLevelSet
  - GeodesicActiveContour

are intended to be used with 3D data.


ITK is N-Dimensional, but the applications are not.



If you want to apply these segmentation methods
to 2D image, you can easily use the examples
available in Insight/Examples/Segmentation which
are command line tools.

You will find detailed information about these
examples in the SoftwareGuide

   http://www . itk . org/ItkSoftwareGuide . pdf

in Section 9.3, pdf-page 363.

---

Note that most of the applications in InsightApplications
are just "demos". They are not bullet-proof and are not
intended to be used for clinical work. Their aim is to
illustrate how you could use ITK in your own applications.



Regards,


    Luis
