Score calibration in face recognition
This paper presents an evaluation of the verification and calibration performance of a face recognition system based on inter-session variability modeling. As an extension to calibration through linear transformation of scores, categorical calibration is introduced as a way to include additional information about images for calibration. The cost of likelihood ratio, which is a well-known measur...
متن کاملBiometric Score Calibration for Forensic Face Recognition
Acknowledgements I would like to thank my PhD supervisors Prof. Raymond Veldhuis and Dr. Luuk Spreeuwers. Their kindness, dedication and attention to detail have been a great inspiration to me. I would particularly thank them for trusting in me and giving me the freedom to choose and follow any research direction that I wanted to persue while at the same time, they were always there whenever I ...
متن کاملThe Role of Score Calibration in Speaker Recognition
The performance of speaker recognition, as measured by NIST in its periodic evaluation programs of speaker detection technology, is affected by the predictive accuracy of system decisions as well as the inherent discriminating power of the underlying algorithms. This paper analyses the score calibration accuracy of a few systems that exhibited good performance in the NIST 2010 speaker recogniti...
متن کاملConfidence-accuracy calibration in absolute and relative face recognition judgments.
Confidence-accuracy (CA) calibration was examined for absolute and relative face recognition judgments as well as for recognition judgments from groups of stimuli presented simultaneously or sequentially (i.e., simultaneous or sequential mini-lineups). When the effect of difficulty was controlled, absolute and relative judgments produced negligibly different CA calibration, whereas no significa...
متن کاملDetection target dependent score calibration for language recognition
Based on the conventional score calibration techniques with gaussian backend and logistic regression of the relative likelihood scores, this paper proposes a method of score calibration specific to a subset of related languages. Detection scores to two related languages are considered as two sources with similar and complementary information. In the proposed score calibration, an optimal linear...
