Frontal face authentication using discriminating
نویسندگان
چکیده
A novel elastic graph matching procedure based on multiscale morphological operations, the so called morphological dynamic link architecture, is developed for frontal face authentication. Fast algorithms for implementing mathematical morphology operations are presented. Feature selection by employing linear projection algorithms is proposed. Discriminatory power coeecients that weigh the matching error at each grid node are derived. The performance of morphological dynamic link architecture in frontal face authentication is evaluated in terms of the receiver operating characteristic on the M2VTS face image database. Preliminary results for face recognition using the proposed technique are also presented.

Face Authentication for Access Control based on SVM using Class Characteristics
Face authentication for access control is a face membership authentication which passes the person of the incoming face if he turns out to be one of an enrolled person based on face recognition or rejects if not. Face membership authentication belongs to the two class classification problem where SVM(Support Vector Machine) has been successfully applied and shows better performance compared to ...
متن کاملFrontal Face Authentication using Variants of Dynamic Link Matching Based on Mathematical Morphology
Two variants of dynamic link matching based on mathematical morphology are developed and tested for frontal face authentication, namely, the Morphological Dynamic Link Architecture and the Morphological Signal Decomposition-Dynamic Link Architecture. Local coeecients which weigh the contribution of each node in elastic graph matching according to its discriminatory power are derived. The perfor...
متن کاملA Bayesian Discriminating Features Method for Face Detection
This paper presents a novel Bayesian Discriminating Features (BDF) method for multiple frontal face detection. The BDF method, which is trained on images from only one database, yet works on test images from diverse sources, displays robust generalization performance. The novelty of this paper comes from the integration of the discriminating feature analysis of the input image, the statistical ...
متن کاملVideo-to-video face authentication system robust to pose variations
High-quality still-to-still (image-to-image) face authentication has shown success under controlled conditions inmany safety applications. However, video-to-video face authentication is still challenging due to appearance variations caused by pose changes. In this paper, we propose a video-to-video face authentication system that is robust to pose variations by making use of synthesized frontal...
متن کاملFrontal face authentication using morphological elastic graph matching
A novel dynamic link architecture based on multiscale morphological dilation-erosion is proposed for frontal face authentication. Instead of a set of Gabor filters tuned to different orientations and scales, multiscale morphological operations are employed to yield a feature vector at each node of the reference grid. Linear projection algorithms for feature selection and automatic weighting of ...
