Automated quality testing of digital imagery for personal documents

The software-hardware system for digital face imagery acquisition and testing for requirements of ISO/IEC FCD 19794-5 standard is described. System contains the following algorithmic modules: face detector; color and intensity characteristics estimator; opened/closed eyes detector; glasses detector, reflexes, shines, and shadows detector; face features detector (nose, brows, mouth); face slope/rotation detector. The precision of face orientation estimation based on monocular digital imagery is addressed. The approach for precision estimation is developed based on comparison of synthesized facial two-dimensional images and scanned face three-dimensional model.
