[Insight-users] Re: Image or Mesh to Tubes

[Luis Ibanez]

Hi Kevin,

Addional methods related to extacting tubes from images
are available at

      InsightApplications/
                DuctExtractor

and using the Hessian filter in

      InsightApplications/
                Curve3DExtractor

There is also a Vesselness filter in

http://www.itk.org/Insight/Doxygen/html/classitk_1_1Hessian3DToVesselnessMeasureImageFilter.html


The challenging aspect in your application is the large size
of the images. In that case you may find more appropriate
a model of tube tracking such as the ones described in Stephen's
publications or like the Crawlers implemented in the Deformable
Organisms papers that Chirs McIntosh and Ghassan Hamarreh suggested.


You will find code for the Deformable Organisms in their recent
paper posted to the Insight Journal
