Face recognition is an indispensable tool for police personal identification. The previous two-dimensional face recognition has faced some obstacles. This is especially the case if the identification of individuals in images or video sequences of crime scenes did not provide a well captured frontal face view.
The aim of this project is to develop an easy to use multi-biometric system for identification of suspect persons from photographs or video data using 3D facial images. This new tool will assist the investigators in their work by making identification possible even from partial facial image captured with low image quality.
Among the innovative solutions in this project is the multi-biometric approach, where different biometric technologies are combined. Along with The Unabhängige Landeszentrum für Datenschutz Schleswig-Holstein (ULD), the data protection aspects in the development of these procedures are considered. The multi-biometric approach involves a novel 3D head scanner, an innovative biometrics using partial 3D face recognition and 3D ear recognition. For the 3D head scanner a cost efficient and easy to use acquisition device is constructed. After successful tests and with the agreement of federal authorities, a 3D face database will replace the existing 2D photographic databases. To enable the matching of non-frontal 2D face images with the existing database, an innovative partial 2D/3D approach is developed. As a new method of identification, 3D ear recognition is developed and integrated into the system. The fusion of those methods to create a robust identification system is another innovation of this project.
The overall system and its possible applications are inspected with respect to the data protection regulation. The right of informational self-determination, problems of possible abuse, the use of biometrics for people with restricted characteristics, and possible health risks are analyzed.
After the end of the project, the system will be further developed to reach market maturity and then it will be offered to national and international police as well as to investigation agencies.
