The quality of input samples is a crucial issue for both verification and identification biometric systems.

Abstract
The quality of input samples is a crucial issue for both verification and identification biometric systems. Literature offers many interesting hints in some contexts, like fingerprint matching, but it is still deficient in others, like face matching. This paper proposes new quality indices for face samples which are based either on the measure of pose or illumination distortion, or on the measure of face symmetry. Results show that they give better results than other proposals in literature. © 2011 ACM.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
