    International Database of Facial Images for Performance and ISO/IEC 19794-5 Conformance Tests
    (BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Ebinger, Peter; Castro Neves, Margarida; Salamon, René; Seibert, Helmut
    Digital face images and fingerprint images are included in all newly issued EU passports [Bus06]. Face images stored within electronic passports (ePass) have to conform to ISO/IEC 19794-5 [Inta] which defines a number of quality requirements for facial image data. A software application (QS Software) is used to verify photographic image properties (pose, head/image size, height-to-page ratio, etc.) as well as setup properties (color depth, contrast, brightness, etc.) [Intb]. To ensure reliability and reproducibility of automated facial image processing systems it is necessary to assess the quality of existing software packages. To this end a database of facial image data would be of significant value as a testing base [HSM06]. The goal for project series FIReBIRD (Facial Image REcognition Benchmark In- cluding Realistic Disturbances) is to establish a database of facial images that can be used worldwide for compliance and performance testing and quality verification based on ISO standards. FIReBIRD will be conducted in close cooperation of Fraunhofer IGD and the German Federal Office for Information Security (BSI) and will be carried out in parallel and in international cooperation with the U.S. National Institute of Stan- dards and Technology (NIST) and the British National Physical Laboratory (NPL). After successful completion of a conceptual framework the international database will be built. This facial image database will consist of distinct data sets used by two separate user groups for two different purposes: public test data that is available for algorithm developers and non-public test data for system evaluation accessible only to authorized organizations such as BSI/Fraunhofer IGD, NPL and NIST.

    Performance Evaluation of Multibiometric Face Recognition Systems
    (BIOSIG 2008: Biometrics and Electronic Signatures, 2008) Castro Neves, Margarida; Chindaro, Samuel; Ng, Ming; Zhou, Ziheng; Deravi, Farzin
    The 3D Face project investigates the use of 3D face recognition technologies, and aims to improve their performance so that it would be possible to use such technologies in unsupervised access control scenarios in airports. During this project novel sensors, 2D, 3D, skin texture matchers and fusion algorithms have been developed. A technology performance test has been performed on all algorithms, in order to evaluate the technology improvements. This paper describes the independent test and evaluation activities for this project and gives an overview of the results obtained.
