[Insight-developers] example image to image filter with different input and output dimensions

[Simon Warfield]

I am having some trouble with a filter that reads 3D data and generates 
4D data.
In particular, the default mechanism for constructing the 4D output 
fails with a bad cast error.

Are there any examples of image to image filters where the output 
dimension is larger than the input dimension ?
