Shape Recognition and finding the location

edit

Hello Everyone,

I have a 3d point cloud data of human head. I have attached few markers (sphere/hemispheres) to the head before scanning the head with laser scanner. I need to find the location (xyz coordinates) of these markers. I was wondering if anyone could help in identifying these markers through shape/pattern recognition or any other technique so that I get the location of the markers. Does this software package has the capability of doing this? Thanks in advance.

Thanks Santosh
