Decision Fusion for Face Authentication
نویسندگان
چکیده
In this paper we study two aspects of decision fusion for enhancing face authentication. First, sequential fusion of scores obtained on successive video frames of a user’s face is used to reduce the error rate. Secondly, the opinions of several face authentication algorithms are combined so that the combined decision is more accurate than the best algorithm alone. The experiments performed on a realistic database demonstrate that the fully automatic multi-frame – multi-experts system proposed in this work allows a significant improvement over the static – single-expert system.

Information Fusion and Person Authentication Using Face and Fingerprint Data
This paper describes the integration of face and fingerprint data to improve the performance of a person identity verification system. In the conetxt of multi-modal person authentication, a set of experts give their opinion as a scalar number, called score, about the identity of an individual. A fusion module receiving as input the scores has to take a binary decision: accept or reject the clai...

Fusion of multiple biometric modalities for human authentication performance improvement has received considerable attention. This paper presents a robust multimodal biometric authentication scheme integrating iris, face and palmprint based on score level fusion. In order to overcome the limitation of the possible missing modalites, the multiple parallel support vector machines (SVMs) fusion st...

Biometrics based personal identification is regarded as an effective method for automatically recognizing, with a high confidence a person’s identity. A multimodal biometric systems consolidate the evidence presented by multiple biometric sources and typically better recognition performance compare to system based on a single biometric modality. This paper proposes an authentication method for ...
متن کاملFusion of face and speech data for person identity verification
Biometric person identity authentication is gaining more and more attention. The authentication task performed by an expert is a binary classification problem: reject or accept identity claim. Combining experts, each based on a different modality (speech, face, fingerprint, etc.), increases the performance and robustness of identity authentication systems. In this context, a key issue is the fu...

This paper suggests the multimodal biometrics system for identity verification using two traits: face and fingerprint. The proposed system is intended to use for the training database includes a face and four fingerprint images for each individual. The final decision is made by first individual score of face and fingerprint compares with enrolled templates and then makes fusion at matching scor...
