[Insight-developers] Proposal: refactoring of image class hierarchy in ITK v4

[Torsten Rohlfing]

  Hi All:

I see that Cory's proposed image class hierarchy includes images with 
non-uniform spacing along at least one axis.

For what it's worth, many years ago I published a paper on how to do 
fast (constant time rather than O(log(Nslices)) coordinate-to-index 
lookups in such images:

T. Rohlfing, "Efficient voxel lookup in non-uniformly spaced images 
using virtual uniform axes," in /Medical Imaging: Image Processing/, 
M. Sonka and K. M. Hanson, Eds., 2001, vol. 4322 of /Proceedings of 
SPIE/, pp. 986-994.

Best,
   Torsten
