The variation in illumination and head pose may decrease the accuracy of two-dimensional face recognition. With the invention of a depth map sensor, more three-dimensional volume data can be processed to mitigate the problem associated with face verification. This paper describes our three-dimensional face verification approach in three phases. First, point cloud library is applied to estimate normal vectors and principal curvatures of every point on a human face point cloud acquired from three-dimensional depth sensor. Next, we adopt deep belief networks to train the identification model using estimated features. Then, face verification is accomplished by using the pre-trained deep belief networks to justify if new incoming face point cloud feature is the one we specified. The experimental results demonstrate that the proposed system performs up to 95% verification accuracy.
