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

[Karthik Krishnan]

Groupwise registration has similar needs. ie. An API in the metric /
cost function superclass to take in an array of images.

Perhaps it calls for a another hierarchy deriving from
SingleValuedCostFunction (for groupwise registration) driven by
variants of the ImageRegistrationMethod

Thanks
