进行人脸表情识别系统相关的算法研究，并基于网络摄像机平台搭建实时人脸表情识别系统。针对经典Retinex算法亮度图像估计运算复杂问题，提出一种Gamma校正的单尺度Retinex图像增强算法；对增强图像进行HOG表情特征提取，并通过最近邻分类器进行表情分类。搭建人脸表情识别系统，进行实时人脸检测与表情识别。测试结果表明该方法具有较高的识别率和鲁棒性。
進行人臉錶情識彆繫統相關的算法研究，併基于網絡攝像機平檯搭建實時人臉錶情識彆繫統。針對經典Retinex算法亮度圖像估計運算複雜問題，提齣一種Gamma校正的單呎度Retinex圖像增彊算法；對增彊圖像進行HOG錶情特徵提取，併通過最近鄰分類器進行錶情分類。搭建人臉錶情識彆繫統，進行實時人臉檢測與錶情識彆。測試結果錶明該方法具有較高的識彆率和魯棒性。

This paper researches on the related algorithm and builds a real-time facial expression recognition system based on net-work camera platform, aiming at the brightness image estimation complexly operated by the use of classic Retinex algorithm, pres-ents a .Gamma correction single scale Retinex image enhancement algorithm, and the enhanced image HOG expression character-istics are extracted and the expression is classified by the nearest neighbor classifier. And then it builds a facial expression recogni-tion system, and completes real-time face detection and face recognition. Test results show that the method is of high recognition rate and robustness.
