[Insight-developers] Complex number interpolation in ITK

[Dominique Zosso]

Hi,

In the itk-wiki proposal on grid computing, Simon Warfield, Steve Pieper 
and Ron Kikinis mention that ITK is currently not able to interpolate 
complex data-type images (see item 4 of the resampling task list: 
"Development and implementation of a resampling algorithm for complex 
number data-types currently not supported by ITK, required for 
interpolation of Fourier transforms.")

Could you please report on the current status of complex data-type 
interpolation in itk? Are there any ongoing developments?

What would you recommend as a possible workaround? One might for example 
think of a intermediate class layer that splits a complex image in two 
real-type images (real and imaginary parts) that are interpolated 
independently? This should not be too hard to implement, but what about 
performance issues?

Looking forward to your opinion

Dominique
