| Abstract: | To solve the technical problem of real-time face detection and break through the bottleneck of AdaBoost algorithm,a hardware acceleration strategy based on FPGA is used to calculate the integral squared image by pipeline architecture.The system can detect a face in 352×288 image at a speed of 50 fps on PowerPC405 VirtexTM-Ⅱ Pro FPGA platform,and achieve a detection rate of 98% with a false alarm rate of 1%,so it can meet the requirements of real-time face detection. |
