Web system for biometric verification of facial portraits

Abstract

The purpose of this paper is to propose a concept and a prototype of a web-based computer system that allows to verify a conformance of the facial image with chosen set of characteristics included in the ISO/ICAO norms. The employed algorithms involve several pattern recognition procedures such as template matching, morphological operators, filtering and calculating several color and intensity characteristics. As a result, the level of conformance is presented to the user, allowing him to make all the necessary corrections in order to produce an image acceptable by the document issuing organization. The experiments showed that chosen approach gives satisfactory results and high level of certainty. Proposed system is implemented as a web service providing simple yet usable graphical front-end (WWW page) connected with server-side processing unit.
