Proceedings ArticleDOI
Evaluation of multimodal biometrics using appearance, shape, and temperature
TL;DR: It is concluded that multi-modal face recognition appears to offer great potential for improved accuracy over using a single 2D image, and larger and more challenging experiments are needed in order to explore this potential.
Face Recognition Using 2-D, 3-D, and Infrared: Is Multimodal Better Than Multisample? Use of multiple images of a face appears to improve recognition accuracy regardless of the type of images that are taken.
TL;DR: Initial results indicate that, using an Beigen-face recognition algorithm and weighted score fusion, multisample techniques can result in a performance increase comparable to that of multimodal techniques.
Proceedings ArticleDOI
Three-dimensional face and finger biometrics
TL;DR: 3D faces offer potential for this application but also exhibit challenges that must be addressed before systems based on 3D face can be fielded, and preliminary results from a study of 3D hand shape biometrics employing curvature classification of the finger skin surface are described.
A New Algorithm for Handling Expression Variation in 3D Face Recognition
TL;DR: This is the first study to compare the PCA and ICP approaches to 3D face recognition, and the first to propose a multiple-region approach to coping with expression variation in 3DFace recognition.
