An application of graphic tools and analytic hierarchy process to the description of biometric features

Abstract

AHP is a well-known method supporting decision-making based on a pairwise comparison process. Previous results of our research show that this tool can be effectively used to describe biometric features, in particular facial parts. In this paper, we present an original and innovative development of this approach augmented by a graphical interface that allows the user to get rid of restrictions in the form of certain numerical (linguistic) values, which were adapted beforehand, answering questions about comparisons of individual features. The presented results of experiments show the efficiency and ease of use of AHP based on a graphical interface in a context of description of biometric features. An application a proper non-linear transformation which parameters can be found on a basis of Particle Swarm Optimization can significantly improve the consistency of expert’s evaluation.
