基于FPGA图像处理技术的人脸检测

Face Detection Based on FPGA Image Processing Technology

利用FPGA高速和并行处理等特性设计了一套人脸检测系统。该系统可对拍摄的人脸图像进行采集、存储、处理和显示等。针对采集的视频图像,采用了快速中值滤波、YCbCr格式转换、灰度变换、肤色二值图形态学滤波和积分的处理方法,实现了人脸准确快速检测。

In this paper,FPGA characteristcs of high speed and parallel processing are used to design a face detection system.The system can collect,store,process and display the captured face images.Methods such as fast median filtering,YCbCr format conversion,grayscale transformation,skin color binary image morphological filtering,and integration processing,are used to deal with the captured video images,accurate and fast detection of human faces is achieved.
