Design of a Three-dimensional Face Recognition System
With the development of computer vision and computer graphics, face recognition technology has gradually developed from 2D to 3D. Using in-depth information of faces, 3D face recognition solves and overcomes the environment and changes in the expression that 2D face recognition encounters. In this paper, the principles of laser triangulation measurement applied in 3D detection and modeling of f...
متن کاملThree-Dimensional Face Recognition ⁄
An expression-invariant 3D face recognition approach is presented. Our basic assumption is that facial expressions can be modelled as isometries of the facial surface. This allows to construct expression-invariant representations of faces using the canonical forms approach. The result is an efficient and accurate face recognition algorithm, robust to facial expressions that can distinguish betw...
متن کاملThree-Dimensional Face Recognition: A Fishersurface Approach
Previous work has shown that principal component analysis (PCA) of three-dimensional face models can be used to perform recognition to a high degree of accuracy. However, experimentation with two-dimensional face images has shown that PCA-based systems are improved by incorporating linear discriminant analysis (LDA), as with Belhumier et al’s fisherface approach. In this paper we introduce the ...
متن کاملExpression-invariant three-dimensional face recognition
One of the hardest problems in face recognition is dealing with facial expressions. Finding an expression-invariant representation of the face could be a remedy for this problem. We suggest treating faces as deformable surfaces in the context of Riemannian geometry, and propose to approximate facial expressions as isometries of the facial surface. This way, we can define geometric invariants of...
متن کاملFace recognition : two-dimensional and three-dimensional techniques
2 ABSTRACT We explore the field of automated face recognition. Beginning with a survey of existing methods applied to two-dimensional (2D) and three-dimensional (3D) face data, we focus on subspace techniques, investigating the use of image pre-processing applied as a preliminary step in order to reduce error rates. We implement the eigenface and Fisherface methods of face recognition, computin...
