Combining 3D and 2D for less constrained periocular recognition

Lulu Chen, James Ferryman
2015 2015 IEEE 7th International Conference on Biometrics Theory, Applications and Systems (BTAS)  
This approach was evaluated using the Bosphorus 3D face database, which contains large variations in facial expressions, head poses and occlusions.  ...  Periocular recognition has recently become an active topic in biometrics. Typically it uses 2D image data of the periocular region.  ...  Also, the 3D shape provides more discriminative features for person recognition.
