[Insight-developers] RE: CenteredTransformationInitializer

[Lorensen, William E (Research)]

No problem. I use ChangeInformation now to center by models. I would not bother to try and slip it
in.

Thanks,

Bill

Bill,

That's right,

The Initializer is ND but requires the transform to have
some methods that right now are only available in the
Centered2D transforms.

I plan to add 'Centered' transforms for 3D. The consequence
is that they will increase their parameters array by
3 elements.

Probably the stability they provide for the optimizer
compensates largely this disadvantage.

I may be able to put a couple of centered 3D transforms during
the weekend so they get included in the release.
