| 摘 要： | 提出一种基于多阈值局部二值模式(MTLBP)的人脸识别方法。计算图像中每个像素点与其局部邻域点的灰度差，通过选择不同的阈值编码形成MTLBP，采用多区域直方图向量进行人脸特征描述，模糊化多阈值匹配结果进行人脸识别。实验结果表明，该方法能很好地结合人脸的纹理和梯度信息，对表情等变化具有较好的鲁棒性。

| Abstract: | This paper proposes a method of face recognition,which is based on Multi-Threshold Local Binary Pattern(MTLBP) . The gray-scale difference is calculated between each pixel and its local neighborhoods of an image. Different thresholds are chosen to code the foregoing gray-scale difference. Face image is divided into multi-regions. Histogram vectors extracted from multi-regions are adopted to describe the human face. Face recognition is completed by blurring the matching results. Experimental results show tha... |
