GENERAL MOTION-BASED FACE RECOGNITION

摘要

A local deformation profile for two or more facial expressions in two or more video clips is generated. The local deformation profile includes motion information such as the direction or magnitude of displacement of a point on the individual's face during the course of an expression. Motion and deformation data from two or more local deformation profiles wherein an individual is expressing different facial expressions may be compared to determine if a same individual is in both video clips. If the individual's localized facial motion is similar in the two video clips it suggests a high confidence in the deformation computation. A small difference in deformation patterns of the video clips along with a similar localized facial motion suggests a same individual is in the two or more video clips. Thus, an individual expressing facial expressions may be identified in video clips.
