Accuracy of the registration of facial 3D scans

[sn-GT]

Hi
I was successfully able to follow the tutorial and use the demo data to run "UnderstandingNonRigidMappingWithMeshMonk.m". Thanks for providing that.

I would like to know how to determine the accuracy of the registration process? Is there an evaluation metric, of how well the target is registered onto the template as well as how accurate are the face vertices?

I have the data with 3D facial scans and I ran through the above matlab script. Visually, the registration did not look as accurate as it was with your demo data. But I would like to compare to accuracy (quantify with an evaluation metric) of registration of my data compared to the demo data. Also, I do not have any manual landmark indications, just the 3D facial scan data - obj, mtl files.

Thanks
