[ITK] Best way to convert 4D image to 3D in-place?

[Dan Mueller]

Hi Chris,

You might want to investigate ' Alternative Memory Models for ITK Images'
http://www.insight-journal.org/browse/publication/646

This contribution is quite old now, so may need significant work to compile
with a recent version of ITK...

Good luck.

Cheers, Dan
