== Image Registration ==
= Outreach =
* Set up the infrastructure to ease the implementation of modern optimization schemes for image registration
** Requires Hessian or pseudo-Hessians of the cost function
** Requires several types of update rules (additive, compositional, inverse compositional, etc.)
** References: "Lucas-Kanade 20 years on" by Baker et al.; "Homography-based 2D Visual Tracking and Servoing" by Benhimane and Malis, "Groupwise Geometric and Photometric Direct Image Registration" by Bartoli; etc.
* Clean up the use of parameter scaling in the optimizers
** One possibility would be that the optimizers only perform unscaled minimization. It would then be up to a cost function wrapper to do the rescaling and potentially return the opposite of the cost function. This is similar to how vnl optimizers are used in ITK
* Optimizers should return the best visited value
** See [http://public.kitware.com/Bug/bug_view_page.php?bug_id=3205 Bug 3205]
* Modify transforms to support a consistent API across transform types
* Modify order of parameters to be consistent across transforms.


== Architecture ==
[[ITK_Release_4/Outreach|Outreach]]
* Implement a pure virtual base class for each API to support instantiation of templated filters at run-time with different dimensions.

= New Code Contribution Process =
* Refactor all the interpolators
** See [[Proposals:Refactoring Index Point Coordinate System]]
** See [http://www.itk.org/Bug/view.php?id=6558 ITK Bug 6558]
** Fix bug 0005335 - transform initializer computes geometric center incorrectly


== Composite Transform ==
[[ITK_Release_4/New_Code_Contribution_Process|New Code Contribution Process]]
* Define a composite transform which can contain any number of transforms, composed.
* Only expose the parameters of the last transform for optimization (default)
* Used in multivariate atlas formation (DTI reg with T1 reg with atlas)
