Sažetak
Recent research has established benefits of rank-level fusion in identification systems ; however, these studies have not compared the advantages, if any, of rank-level fusion schemes over classical score-level fusion schemes. In the presence of low quality biometric data, the genuine match score is claimed to be low and expected to be an unreliable individual output. Conversely, the rank assigned to that genuine identity is believed to remain stable even when using low quality biometric data. However, to the best of our knowledge, there is not a deepen investigation on the stability of ranks. In this paper, we analyze changes of the rank assigned to the genuine identity in multi-modal scenarios when using actual low quality data. The performance is evaluated on a subset of the database Face and Ocular Challenge Series (FOCS) collection (the Good, Bad and Ugly database), composed of three frontal faces per subject for 407 subjects. Results show that a variant of the highest rank fusion scheme, which is robust to ties, performs better than the other non-learning based rank-level fusion methods explored in this work. However, experiments demonstrate that score-level fusion results in better identification accuracy than existing rank-level fusion schemes.
