Identifying faces using multiple retrievals

Abstract

To facilitate crime investigation, a team at the Institute of Systems science designed Computer-Aided Facial Image Inference and Retrieval System (CAFIIR) which was a database management system was incorporated to mug shot identification. The system was based on the expert feedbacks of crime investigators. It encompassed physical traits as well as subjective descriptions that require fuzzy searching. For fuzzy subjects, a mapping function was employed. The CAFIIR system also provided for any inaccuracy or shortcomings of the descriptions given by the witness and investigators, rendering a practically foolproof program.
