چکیده

In general, most systems for face and speaker identification are tested on high quality data collected in well-lit and quiet environments. In this study, we investigate the application of existing face and speaker identification techniques to the task of user authentication on a handheld device. In this context, the audio/visual capture hardware is of lower quality than equipment typically used in laboratory experiments. Additionally, variable background conditions which can degrade the audio/visual signal may be present. These factors can be expected to harm the performance of the system. Under these circumstances, using a combination of biometric modalities can improve the robustness and accuracy of the person identification task. In this paper, we present our approach for combining both face and speaker identification technologies on a handheld device, and experimentally demonstrate a fused multi-modal system which achieves a 90% reduction in equal error rate over the better of the two independent systems.

ISL Person Identification Systems in the CLEAR 2007 Evaluations

In this paper, we present ISL person identification systems in the CLEAR 2007 evaluations. The identification systems consist of a face recognition system, a speaker identification system and a multi-modal identification system that combines the individual systems. The experimental results show that the face recognition system outperforms the speaker identification system significantly on the s...

Combining voiceprint and face biometrics for speaker identification using SDWS

The biometric system that uses multiple biometric traits promises higher identification accuracy than identification in either individual domain. To reach this goal, special attention should be paid to the strategies for combining voiceprint and face experts. We propose an improved weighted sum rule based on the scores difference (SDWS) between the genuine speaker class and the mistaken speaker...

Substitution as a Device of Grammatical Cohesion in English Contexts

The present study set out to investigate the effect of teaching substitution as a kind of grammatical cohesion on the true identification of confusing substitution elements with cohesive or non-cohesive roles in different contexts and also the production of modal, reporting and conditional contexts through clausal substitution acquaintance. To this end, the following procedures were taken. Firs...

On the Improvements of - Uni-modal and Bi-modal Fusions of Speaker and Face Recognition for Mobile Biometrics

The MOBIO database provides a challenging test-bed for speaker and face recognition systems because it includes voice and face samples as they would appear in forensic scenarios. In this paper, we investigate uni-modal and bimodal multi-algorithm fusion using logistic regression. The source speaker and face recognition systems were taken from the 2013 speaker and face recognition evaluations th...
