[Insight-users] another (quicker) level sets question

[Zachary Pincus]

Hello,

I've got another and more brief question as to using ITK's level set 
segmentation framework.

To wit, what is the recommended way of creating a level set method that 
uses "custom" speed and edge advection images? It seems that one could 
either:
(a) subclass SegmentationLevelSetImageFilter and 
SegmentationLevelSetFunction, which is how the various methods like 
Curves or Shape Detection are implemented in ITK, or
(b) create a generic SegmentationLevelSetImageFilter object and plug in 
custom advection and speed imaged with that class's methods for this 
purpose.

Are these approaches functionally equivalent? Are there caveats with 
one or the other?

Thanks,
