摘要： 针对复杂背景下的人脸图像，提出一种快速人脸检测识别方法。包括基于肤色模型和OpenCV的综合方法进行人脸检测定位，并对图像重新保存、预处理，用以克服光照因素的干扰，剔除复杂背景对人脸识别不利因素的影响。采用二维主成分分析算法，对同一个人多幅不同表情的人脸图像进行采集和特征提取并归类。对ORL人脸库及实际外场背景下的人脸图像进行测试，结果表明，该方法可有效解决复杂背景下的人脸识别问题，具有快速、高效的实用性，正确识别率可达90%以上。

Abstract: This paper proposes a fast face detection and recognition algorithm based on face image in the complex background. The process includes complexion model and OpenCV integrated method to solve face detection and location, re-save image, pretreatment, and illumination influence will be conquered effectively, eliminates the disadvantage factor disturbance of complex background. Afterward, it adopts Two-dimensional Principle Component Analysis(2DPCA) algorithms to collect face image of different expression which comes from the same human and distill character, and classifies the similar face image. By ORL database and outfield face image test, experimental results show that this method resolves face location and recognition effectively in the complex background and has more fast and effective practicability than other means, over 90% correct recognition rate.
