Researchers at Imperial College London and the Royal Free Hospital in the U.K. are scanning volunteers' faces to compile a database of three-dimensional computer models with different expressions, ethnicities, and age groups, which could be used to aid in reconstructive surgery.
The data generated by the scanners is sent to the Imperial research group, which for the last 10 years has been developing a system for quickly analyzing thousands of faces. A program maps the various facial landmarks and assigns them coordinates so direct comparisons can be made between the scans. The team then accrues a statistical model of how an average face appears in different stages of growth and in different ethnicities.
In addition to surgical applications, the researchers believe their system could be useful as a facial-recognition tool, as an enhancement for lie detection, and as an expression tool for autistic children.
