Intelligent Expression-independent Face Recognition Algorithm
Chao Li, Armando B. Barreto · 2006
Robotic vision has always been an important topic in robotics research. In this paper an algorithm is proposed to try to endow the robot with the ability to recognize a person by his/her 3D face image. Unlike most previous approaches, this algorithm uses a framework of integrated expression recognition and face recognition to deal with the challenge of expression-independent face recognition. The algorithm is based on the probabilistic methods to model the variation between expressional faces and neutral faces. Experiments were performed on a database of 30 subjects. Each of the subjects contributed two smiling expression images in addition to two neutral expression images. Experimental results proved the feasibility of this framework.
