This paper considers biometric face verification using elastic graph matching, fulfilling the requirements for mobile devices regarding performance, low complexity, and low-power consumption. Two feature extraction techniques are compared. A modified technique based on normalized mathematical morphological features is introduced, that results in performances comparable to ones achieved with Gabor features, however, with a substantially lower computational complexity.
