[Insight-users] Dense Transformations in ITK

[Peter Lorenzen]

Hello,

I am considering developing an ITK-based high-dimensional image 
registration application where the transformation involved is a dense 
map (i.e. for n-dimensional data, an n-dimensional vector at each 
indexed spatial location). Although ITK provides a great number of 
transformation models, does anyone know if there are plans specialize 
itk::Transform to implement a dense map?

To illustrate the meaning of "dense" consider:

   typedef itk::Vector< float, ImageDimension >  VectorType;
   typedef itk::Image< VectorType, ImageDimension >  
DenseTransformationType;

In the ITK transformation framework, we would want something along the 
lines of itk::DenseTransform instead.

I can certainly use the itk::Image< VectorType, ImageDimension > model 
above, but it would be nice use the existing ITK registration framework 
(i.e., define a metric, optimizer, etc. and connect a series of 
existing filters) instead.

Thanks,

- Peter
