Top Level Goals

Composite Transform
Deformation Field Transform
Transform reorganization of parameters management
- Transform parameter object
- Support for very large number of parameters
- Refactoring Jacobian computations
- Optimizers refactoring (no longer holding parameters array)
- Metric refactoring (new management of Transform parameters)
Optimizer Refactoring
- New Optimizers Family (not holding parameters themselves)
  - Optimizer base (new class)
    - Gradient descent optimizer
Multi-Component Metric
Demons Metric
PointSet Metrics
Multi-Threading Rewriting of Metrics
Poly-Affine Transform (combination of Affine and Deformable)
- Transform per region (plus interpolation in-between regions)
Multi-Resolution
