[Insight-users] Wrapping ImageToImageFilter with high-dimensional pixel type

[Tobias Maier]

Hi all,

I have implemented a filter to extract features on 3D images. It is a 
ImageToImageFilter with output type itk::Image< 
itk::CovariantVector<float, dim>, 3>. The dimension is calculated from a 
parameter given as template parameter and usually high.

Using this filter from C++ Code works fine, but because of the high 
dimensions of the CovariantVector (>10) wrapping the code for python 
requires a lot of effort to wrap the required types (Vector, FixedArray, 
Image, ...) without wrapping everything for this long vectors.

Using a 4D image as output would make the wrapping easy, but I do not 
like the mixing of features and image dimensions.

Do you know a solution that makes wrapping feasible while keeping the 
interface clean?

Thanks for any help you can provide.
