In order to realize the real-time face recognition in video by embedded system, the design scheme of fast face recognition system based on TI TMS320DM642 was presented, and optimization policy was proposed in terms of both hardware and software. Firstly, effective features were selected, and the algorithm of face detection and recognition was briefly introduced, then according to the algorithm, the design scheme and function units of hardware system were described. Finally, the algorithm was transplanted onto the hardware system, then the optimization policy was applied, and fast embedded face recognition system was implemented. The experimental results demonstrate the system works reliably, the running speed of algorithm was improved markedly, and real-time face recognition in video was realized.
