摘要
设计实现了一种基于DSP的嵌入式图像识别系统。该系统采用专用视频输入处理芯片SAA7111和DSP实现了数字图像的采集、预处理、特征提取及识别,且对系统中的图像采集、图像处理、USB通信模块以及系统的升级维护方法进行了介绍,给出了基于该系统的人脸识别方案及测试结果。
In this paper, we design and implement an image recognition system, in which the Philips＇s SAA7111 and TI＇s C5509 are used to realize the image collection, preprocessing, feature extraction and recognition. Image acquisition, image processing, and USB communication model are emphasized in this paper. Finally, the application of face recognition based on the system and the experiment results are presented.
