Abstract: To overcome the shortages of traditional access control system of face recognition, which is of poor stability and low speed, the design scheme of access control system of face recognition based on dual-core Digital Signal Processor (DSP) was presented. The system structure and software realization technology were discussed. The speed of face recognition was improved through dual-core and code optimization techniques. The experimental results show that the system is of good stability, high recognition rate and high speed, and it is practical.

Key words: face recognition, access control system, code optimization, dual-core Digital Signal Processor (DSP)
