[Insight-users] 2d 3d registration with multiple 2d images

[brian avants]

This is an interesting question.   Registration refactoring will
address this by formulating the problem as a multi-valued
optimization.   Is it the case that the 2d images are "in the same
space"  i.e. already in some physical correspondence to each other?
If so, then the algorithm would be something like:

- Declare "registration machines" for each of the 2D-3D problems.
- Registration machines contain the image pairs, optimizers, metrics
for each problem.
- Pass the machine set to a multi-resolution , multi-valued
registration coordinator.
- The coordinator will determine how to combine the output of each machine.

Would this type of approach work for  you?
