The use of face as a biometric identifier has some drawbacks: Lso, due to the lack of clear specifications and of an appropriate benchmark, comparing the performance of such systems is not easy. It requires less detail, which makes it suitable for less demanding applications.
If in color, it 1974-5 show skin tones naturally. The photograph showed below have been published by ICAO. Four face image types are introduced to define categories that satisfy the needs of different applications, and the requirements above are specified for each image type:.
Images labeled as dummy for a given characteristic are of course excluded from the corresponding test. Izo of the applicant and background The lighting shall be uniform with no shadows and no reflections on the face, no red eyes and the background shall not present any remarkable shadow. The database is supplied with the ground-truth data needed for an objective performance evaluation; in particular the following information is given for each image: The rest of images are used for testing.
Children States may issue special recommendations for children. Those recommendations are used in several countries also for the issuance of driver licenses or residence permits. Colours and lighting The portrait shall be colour neutral showin the applicant with eyes open and clearly visible.

A precise formalization is here proposed to limit as much as possible the ambiguity. Reflexion on the face.
For teststhe number of images n i included in the subset related to oso characteristic i is: A smile with closed mouth is permitted. The geometric requirements are specified as a function of some measures represented in the following figure; Photographic and pose-specific tests: The frames shall not cover any part of the eyes.
