[Insight-users] Curve/Surface representation and operations

[Brecht Heyde]

Hi,

Could you supply me with some vtk classes which would support the functionality I am looking for?
Does vtk make use of imageiterators as well which would allow to quickly move around the inner/outer side of a contour/surface?

I tried it once but not successful. I then turned to use VTK which supports more geometry stuff. It is not hard to connect ITK with VTK, so that might be one solution.

Dear all,

I am not really familiar with how curves and surfaces are typically represented in ITK. I found PolyLineParametricPath as an example, but that is only for two dimensions (see: http://www.itk.org/Wiki/ITK/Examples/Curves/PolyLineParametricPath). I would like to have a representation which is easily scalable to 3D. In practice this surface does not necessarily have to be a closed surface.

For example, what would be the best way to proceed for the following simple operations, given an initial contour (let’s say in 2D):

-          Calculate the mean intensity of the image above/below the contour over a certain distance

-          Calculate the (local/mean) curvature of the curve

Best,
Brecht Heyde
