[MINC-users] label from 2 objects

[Simon Fristed Eskildsen]

Hi Mishkin,
Is it a very dense object, i.e lots of vertices? If so, the vertices per voxel (VPV) should be increased, not decreased. It's simply the maximum number of vertices you would expect within a single voxel of the input volume in order to make a static allocation. I know it's ugly, but this limits the memory usage and runs in linear time. 50 VPV seem to work for most of my surfaces. You could try setting it to 100 or higher. Watch the memory usage, though.
