Face matching across 2-D and 3-D representations (2004)
Presentation / Conference Contribution
Young, A., Liu, C., & Ward, J. Face matching across 2-D and 3-D representations

Research on face recognition has mainly relied on photographic or video stimuli where the 3-D volumetric information of a face for both training and test materials is limited to the depth cues given by the 2-D pictorial representation.
