We examine inter-session variability modelling (ISV) and joint factor analysis (JFA) for both face and speaker authentication and evaluate our system on the largest bi-modal mobile authentication database available, the MOBIO database, with over 61 hours of audio-visual data captured by 150 people in uncontrolled environments on a mobile phone. Our system achieves 2.6\% and 9.7\% half total error rate for male and female trials respectively – relative improvements of 78\% and 27\% compared to previous results.}, pdf = {https://publications.idiap.ch/attachments/reports/2012/Motlicek_Idiap-RR-18-2012.pdf} }
