No one expects the Spanish Inquisition…

Biometrics refers to a method of computer identity recognition based upon a set of biological measurements taken from a human subject. Dr. Lau’s expertise in biometrics extends from his work in structured light illumination where he has experience in both fingerprint and face recognition from 3-D scans. Face recognition, in particular, benefits greatly from 3-D where traditional 2-D recognition fails in the presence in pose and illumination variance.
