Summary:Quality measurement of digital passport photographs is a complex problem. The first problem to solve is to establish the quality metrics, quality scales and the level of acceptance for a certain quality. The second problem to solve is to offer an integrated system which covers the principles of software engineering plus a user-friendly interface. This paper introduces the solution for both problems. The method to calculate different and novel quality metrics based on a conventional estimation and a quality metric based on nonconformance of quality requirements for digital passport photographs. Conformance clauses of quality requirements were obtained from the specifications of the machine readable-travel documents (MRTD) document of the International-Civil Aviation Organization (ICAO) ICAO/MRTD and from the document of the International Standardization Organization (ISO). Series of algorithms were implemented to measure the quality of passport photographs in two ways: as an image and as a biometric sample.
