| 摘 要： | 本文是在ZYNQ平台上，结合加入阈值处理的背景减除法实现人脸检测的快速实现。ZYNQ是ARM+FPGA的体系架构，本文利用该芯片的PL（FPGA）端来实现图像的预处理；利用PS（ARM）端对来自PL端的图像利用背景减除法进行前景的提取，然后对前景图片进行人脸检测。最终，本文实现了人脸检测的时间在ZYNQ平台上平均减少了700ms以上，而且在识别率方面也有所提高。

| Abstract: | This paper is focused on fast implementation of face detection by using background subtraction method which is added the threshold on the ZYNQ platform.ZYNQ has a framework of ARM+FPGA,and in this paper,the PL which is the FPGA in the chip is used to achieve pre-processing of the image;the PS which is the ARM in the chip is used to implement background subtraction for the image from PL,then to finish the face detection.Finally,this paper implements the reduction of face detection time more than 700ms,and the recognition rate is also improved on ZYNQ. |
