| Abstract: | An embedded real-time face detection system has been designed and developed in the Intel PXA270 core board after the analysis of the face detection algorithm AdaBoost and the OpenCV library.This system does not depend on any other kinds of GUI,but uses the V4L API and FrameBuffer API to get and display video frames.According to the characteristics of the embedded platform,the program is optimized and a function's bug has been solved in the OpenCV version 1.0 when excuted in the embedded platform.To a certai... |
