UR3D-C: Linear dimensionality reduction for efficient 3D face recognition
Biometrics, International Joint Conference on
By Omar Ocegueda,Georgios Passalis,Theoharis Theoharis,Shishir K. Shah,Ioannis A. Kakadiaris
Issue Date:October 2011
We present a novel approach for computing a compact and highly discriminant biometric signature for 3D face recognition using linear dimensionality reduction techniques. Initially, a geometry-image representation is used to effectively resample the raw 3D ...
SHREC'08 entry: 2D/3D hybrid
Shape Modeling and Applications, International Conference on
By Panagiotis Papadakis, Ioannis Pratikakis, Stavros Perantonis, Theoharis Theoharis, Georgios Passalis
Issue Date:June 2008
In this paper, we present an overview of the 3D object retrieval method that we employed in our participation to the Generic Models track of SHREC 2008 organized by the AIM@SHAPE network of excellence. The proposed methodology is detailed in . Our metho...
Three-Dimensional Face Recognition in the Presence of Facial Expressions: An Annotated Deformable Model Approach
IEEE Transactions on Pattern Analysis and Machine Intelligence
By Ioannis A. Kakadiaris, Georgios Passalis, George Toderici, Mohammed N. Murtuza, Yunliang Lu, Nikos Karampatziakis, Theoharis Theoharis
Issue Date:April 2007
In this paper, we present the computational tools and a hardware prototype for 3D face recognition. Full automation is provided through the use of advanced multistage alignment algorithms, resilience to facial expressions by employing a deformable model fr...
