| 摘 要： | 为提高人脸识别的准确度,提出了一种基于低分辨率局部二值模式的人脸识别方法。该方法将原始人脸图像滤波下采样处理成低分辨率图像,将其划分成若干块矩形块图像,对每一块图像进行局部二值模式计算,统计出每一块LBP图谱的直方图,再连接在一起成为这幅图片的最终特征向量。经实验表明,该算法在ORL和YALE上均取得了更好的识别效果,且对光照、表情、姿势等的变化具备鲁棒性。

| Abstract: | In order to improve the accuracy of human face recognition,a novel Low Resolution Local Binary Pattern(LRLBP) method is proposed.First,the low-resolution image is obtained from the original image through wave filter and down-sampling.Second,the obtained image is divided into non-overlapping rectangular regions and the histogram of each region is computed independently.Finally,these histograms are concatenated as the feature vector of the human face.Experiment results on ORL and Yale face databases show that the proposed LRLBP method can get high human face recognition rate and that the method is robust to illumination,face expression and position variations. |
