[Insight-users] Resample Time

[Li, George (NIH/NCI)]

Hi, Luis and all:

The resampleFilter seems taking longer than expected time
to update(), usually around 30 seconds, roughly about 500
iteration time for OnePlusOneEvolutionary optimizer with
Mattes metric on my computer.

Is there a way to improve the performance? Or I did miss
something? I would think voxel coordinate transformation,
linear interpolation and voxel reassignment should not
take more than 3 seconds for a regular sized volume, such
as 320x320x100 volume.

Thanks,

George
