Andreopoulos A. and Tsotsos J. K., Resampling 4D Images Using Adaptive Filtering, In Proceedings of the
2nd Canadian Conference on Computer and Robot Vision, Victoria, Canada, 2005.

Abstract:
We present an adaptive filtering based methodology for
resampling 3-D time series images using an extension of the
method presented by Westin in [11]. We simultaneously reduce
the artifacts due to image noise and resample the data
on a finer grid along the time dimension. This provides a
methodology for obtaining high quality image resampling
without the disadvantages of staircase artifacts created by
more common interpolation methods such as linear interpolation.
We present qualitative results of the algorithm on
a data set of 4-D cardiac MRI. This is a useful approach
for any situation where we have a data set of 4-D images
needing to be resampled.  [PDF]
