[Insight-users] Non-rigid algorithms

[Dalal, Dhaval]

Hi everyone,
I am quite new to this group.
I have to perform non rigid registration of 2 mice mri images and thn apply
this transformation function on to an atlas (well defined segmentated image)
in order to generate pilot segmentations of the raw image.
My questions are
- which non-rigid algorithms(source code)is available on the net.
i ahve come across only itk and air so far.
- which website/paper has the best literature on non-rigid algorithm to
start off.
any help will be greatly appreciated,
thanx
