| 摘 要： | 首先分析了人脸图像不同的方向性细节对识别率的影响,提出了水平分量优先原则。结合该原则提出了一种基于多尺度区域性-方向性加权的规范型二元局部纹理描述算子RDW-LBP的鲁棒人脸识别算法。算法通过多尺度Haar小波分解,提取多级尺度分量和含有最多有效识别细节的一级水平细节分量,组成待分析系数子图矩阵M。计算矩阵M的RDW-LBP纹理特征图谱,结合子区域剖分,连接子区域特征共同组成人脸图像特征向量,最后使用基于Chi-Square距离的分类器进行识别。

| Abstract: | In order to improve the recognition rate and robustness of face recognition algorithms,the impact of different directional details of facial images on recognition rate is analyzed,and a Horizontal component prior principle(HCPP) is proposed.Then a robust face recognition algorithm based on Regional directional weighted local binary pattern(RDW-LBP) is proposed,in which HCPP is employed.The face image is decomposed by multi-scale Haar wavelet to extract multi-level scale coefficients and the first level hori... |
