Abstract :
This paper proposes techniques for face detection and gives the implementation details for an FPGA development board. We analyze and discuss the relation between the system computation cost and selection of the image scaling factor. We give a new method to select the stop threshold for the image reduction process, which reduces the total computation by half. We also provide a color image output mode to let our system enjoy more human-oriented design. Test results show that the system achieves real-time face detection speed (100 fps) and a high face detection rate (87.2%) for an SVGA (600 × 800) video source. The low power consumption (3.5W) is another advantage over previous work.
