针对实时人脸识别易受光照变化影响的问题,提出了一种将局部二值模式(Local Binary Patterns,LBP)与嵌入式隐马尔可夫模型(Embedded Hidden Markov Model,EHMM)相结合的人脸识别方法.该方法首先对输入的人脸图像进行LBP预处理,接着对其进行特征向量提取,最后把提取的特征观察向量送入EHMM进行训练或识别.在多个人脸数据库上进行了实验,结果表明该文算法对光照具有较好的鲁棒性,提高了识别率.
針對實時人臉識彆易受光照變化影響的問題,提齣瞭一種將跼部二值模式(Local Binary Patterns,LBP)與嵌入式隱馬爾可伕模型(Embedded Hidden Markov Model,EHMM)相結閤的人臉識彆方法.該方法首先對輸入的人臉圖像進行LBP預處理,接著對其進行特徵嚮量提取,最後把提取的特徵觀察嚮量送入EHMM進行訓練或識彆.在多箇人臉數據庫上進行瞭實驗,結果錶明該文算法對光照具有較好的魯棒性,提高瞭識彆率.

A combination of Local Binary Pattern(LBP) with Embedded Hidden Markov Model(EHMM) is set up for against the sensitivity of real-time face recognition in the case of lighting variation. Face images are preprocessed according to LBP and then eigenvectors are extracted from consequences. Thereby, extracted observation vectors can do training or identification in EHMM. Experiments are conducted on several face database and numerical results verify the robustness of illumination, thus im?prove the recognition rate.
