Hi,

Can you tell me the differences between those two filters ? It seems to me that the same filter has been implemented under 2 different frameworks.

[https://itk.org/Doxygen/html/classitk\_1\_1SatoVesselnessFeatureGenerator.html](https://itk.org/Doxygen/html/classitk_1_1SatoVesselnessFeatureGenerator.html)

Cheers,  
Jonas

You might be right they are the same, but there is probably some twist to Sato. LesionSizingToolkit made some modifications to standard filters. I remember they had some non-trivially modified Canny variant. Maybe this is one of those instances. I definitely recommend going with `Hessian3DToVesselnessMeasureImageFilter`, as it is part of the main library.

I’ll stick to the `Hessian3DToVesselnessMeasureImageFilter` then, thanks for the clarification !
