Distance transform / 3d nearest neighbor [message #40532] Thu, 12 August 2004 16:32

I need to do a series of calculations concerning relationships between
nearest neighbors on surfaces. IDL provides MORPH_DISTANCE that gives
Euclidean distances, but it does not give the indices of the actual
nearest-neighbor voxel. Is there any alternative function to provide
this information? If not, is there a clever way to calculate the
nearest neighbor that is not order N^2?
