[Insight-users] Help for using Canny edge detection in 3D data

[Sergio Vera]

Hello Rong,

the documentation of
http://www.itk.org/Doxygen/html/classitk_1_1CannyEdgeDetectionImageFilter.html#details
states
that the input image can have arbitrary dimensions. So, you should be able
to use canny edge detector on 3D images. Follow this example
http://www.vtk.org/Wiki/ITK/Examples/Broken/EdgesAndGradients/CannyEdgeDetectionImageFilter
but
be aware that this is also a 2D example. Your code should be the same except
for the image template definition step where you should use the proper image
template (3 Dimensions)

Best regards,
Sergio
