Sub-voxel Medial Axis traces

Gaile's Face

Gaile's face was scanned a few years ago using a laser scanner. I first extracted the frontal part of her face from the original cloud of datapoints by simple clipping. Then I processed this cloud of point - shown as yellow dots below - using my sub-voxel tracing of medial sheets - shown as white dots - combined with my 3D wavefront propagation algorithm. There are 12623 points in this datasets (input to the wavefront algorithm). It takes a few minutes to run on my workstation (SGI Indigo2), over the local network.
