Gait Gate: An Online Walk-Through Multimodal Biometric Verification System Using a Single RGB-D Sensor
نویسندگان
چکیده
This paper introduces the Gait Gate as the first online walkthrough access control system based on multimodal biometric person verification. Face, gait and height modalities are simultaneously captured by a single RGB-D sensor and fused at the matching-score level. To achieve the real-time requirements, mutual subspace method has been used for the face matcher. An acceptance threshold has been learned beforehand using data of a set of subjects disjoint from the targets. The Gait Gate has been evaluated through experiments in actual online situation. In experiments, 1324 walking sequences have resulted from the verification of 26 targets. The verification results show an average computation time of less than 13 ms and an accuracy of 6.08% FAR and 7.21% FRR.

A Survey of Biometric Gait Recognition: Approaches, Security and Challenges
Biometric systems are becoming increasingly important, since they provide more reliable and efficient means of identity verification. Biometric gait recognition (i.e. recognizing people from the way they walk) is one of the recent attractive topics in biometric research. This paper presents biometric user recognition based on gait. Biometric gait recognition is categorized into three groups bas...

Biometrics is an automated authentication mechanism that allows the identification or verification of individual based on unique physiological and behavioural characteristics. The combination of two or more biometric technologies in one application, better known as a multimodal biometric system, can provide enhanced security. Apart from the sound choice of fusion methodologies for the combinati...

User verification systems that use a single biometric indicator often have to contend with noisy sensor data, restricted degree of freedom, non-universality of the biometric trait and unacceptable error rates. So the need of using multimodal biometric system occurred. A multimodal biometric system combines the different biometric traits and provides better recognition performance as compared to...

In this paper we have developed a robust human identification scheme from low-resolution surveillance video footage. For establishing the human identity; we also carried out a comparative study with two multimodal biometric databases (UCMG and CASIA), two different gait databases with different complexities. For experimental validation of our scheme, we used several dimensionality reduction alg...
