Biometrics face verification feature extraction graph matching low-power

Abstract

Biometric face verification using elastic graph matching is considered and two feature extraction techniques used as a pre-processing stage are compared. Low-complexity vs. performance is of particular interest for mobile devices. A modified technique based on a normalization of mathematical morphology feature is introduced and show a performance comparable to that of Gabor features at a much-reduced computational complexity.
