Face Sample Quality
نویسندگان
چکیده
Face is a human biometric attribute that can be used to establish the identity of a person. A face-based biometric system operates by capturing probe face samples and comparing them against gallery face templates. The intrinsic characteristics of captured face samples determine their effectiveness for face authentication. Face sample quality is a measurement of these intrinsic characteristics. Face sample quality has significant impact on the performance of a face-based biometric system. Recognizing face samples of poor quality is still a challenging problem. A number of factors can contribute towards degradation in face sample quality. They include, but not limited to, illumination variation, pose variation, facial expression change, face occlusion, low resolution and high sensing noise.

Performance of biometric systems depends on quality of acquired biometric samples. Low sample quality is the main reason for matching errors in biometric systems and may be the principal weakness of some implementations. Therefore, when a biometric system obtains a sequence of person images from a surveillance camera, the quality of the different face images has to be evaluated before performin...
