[Insight-users] Question related to Demons algorithm and FEM

[Ruben Schilling]

Hi,

you might search this list using Google to see what other uses asked  
in the past, but I would recommend you to read the research papers to  
understand what the algorithms do. You can then read the  
implementation in ITK line by line.

Run time of the algorithm depends on your parameter settings. As far  
as I know binary should be ok for FEM, although I don't know whether  
it makes sense to throw away grayvalue information in your case.
If you have a more specific question post it again.

Search this mailinglist via Google without time constraints by typing

Ruben
