I’m trying to implement “The Multiscale Bowler-Hat Transform for Vessel Enhancement in 3D Biomedical Images” by creating a custom itk filter.
They use morphological grayscale openings with a combination of spheres and 3D lines structuring elements. The lines structuring elements are oriented in several directions.
I would like to know how to make 3D oriented line structuring elements with ITK.
There is the itkFlatStructuringElement, but I don’t know if the Box function is the one I’m looking for. The documentation is a bit short and the examples on the wiki have been removed with the near ITK 5.0 release.
I also found the LineIterator to draw custom lines using two points. But the result probably won’t be usable by GrayscaleMorphologicalOpeningFilter…
Any pointers on how to proceed ?
