| Abstract(in English) | This paper reports a probabilistic veri?cation method using multi-feature for environment-robust biometrics. In biometrics, veri?cation is performed by comparing features which are extracted to contain individuality from biometric information such as face images. However, as well as individuality, those features contain undesired information derived from environmental variations where biometric information is captured. The undesired information is mixed the feature as distortions and degrades veri?cation performance. Toward to environment-robust veri?cation, probabilistic linear discriminative analysis (PLDA)-based veri?cation has been studied. PLDA models individuality space and environment space with large learning data and can perform veri?cation referring both of twospaceinwhole. Inthispaper, PLDAisextendedtodealwithtwokindsoffeaturesextractedfromonebiometric information simultaneously. This proposed model can model individuality space and environment space with the two kinds of features. In results of experiments using face images, the proposed model is superior to conventional PLDA. |
