Rubberface : Physics-based mesh fitting for 3D facial scans

The aim of this project was to define, implement and evaluate a physics based model, which would only require small amounts of manual input, forfitting a mesh to facial scans. Our idea was to use a mesh built of springs, and simulate mechanical forces on the mesh to fit it to scan data. The locations of some predefined key facial features, the only manual input needed, served as hard constraints for an initial rough fit. A finer and more detailed fit was obtained by applying an imagined force field from the scan data on the mesh. Despite some irregularities in the results, to which we have suggested possible solutions or model improvements, the approach appears to be viable.
