I’m trying to use the brand new SimpleITK procedural interface to the ObjectnessMeasureFilter.
Since it automatically computes the Hessian Matrix of the image, I’d like to know which sigma value is used for this purpose. If I’m not mistaken, it is a crucial parameter of this filter.
Thanks for your help.
There is no sigma. It computes the Hessian directly on the provided image via discrete differences. Simply run a your favorite Gaussian filter before.
I apologize I have a draft of an Insight Journal paper which describe some of these details I need to finish.
I see, thank you for the very quick answer.
