Abstract :
A fully automatic framework is proposed for 3D face recognition and its performance is justified by the FRGC database. 3D facial representation extracted by the Dual-tree Complex Wavelet Transform (DT-CWT) is introduced to reflect the facial geometry properties. Low redundancy makes it more effective and efficient to describe the discriminant feature in 2.5D range data. In this paper, DT-CWT is used in conjunction with Weighted Spherical Face Representation to form a rejection classifier, which quickly eliminates a large number of candidate gallery faces. The remaining faces are then verified utilizing sparse representation based classification. Our method achieves the verification rate of 98.86% on All vs. All experiment at an FAR of 0.1%.
