Recently, different research groups have found that the gallery composition of a face database can induce performance differentials to facial identification systems in which a probe image is compared against up to all stored reference images to reach a biometric decision. This negative effect has been referred to as “watchlist imbalance effect” by the researchers and exhibits high relevance in real applications of biometrics, most prominently in identification searches against criminal databases and blacklists.
