ABSTRACT：哥也色地址

This paper is aimed at solving the problems that LBP feature contains outlier and the dimension of LBP feature is too high， and a fast and effective face recognition algorithm based on Robust Local Binary Pattern is proposed. The main idea of RobustLBP is setting a Robust function on the basis of original LBP. First， it calculates the Mahalanobis distance between the mean vector and every dimension as the argument of Robust function and estimates a set of important information by making Robust function convergence. Then， it obtains a transformation matrix which is used to reject outlier of original feature by using the information. Lastly， it compares the Chi-square distance among the features after reducing dimension in order to complete face recognition. Extensive experiments on FERET， CASPEAL-R1 and LFW face databases validate the effectiveness of face recognition.

摘 要：

本文针对LBP算法特征包含outlier和维渡过高的问题提议了一种基于鲁棒的局部二值时势(RobustLBP)的快速有用的东谈主脸识别算法。RobustLBP算法的想想是在LBP算法的基础上加上一个Robust函数撤退outlier达到降维的盘算推算。最初通过计较LBP特征各个维度和中心元素的马氏距离动作Robust函数的输入，使得Robust函数不断估算出首要信息。然后把握这些信息求出变换矩阵撤退原始LBP特征的outlier。临了比对降维后特征间的卡方距离结束东谈主脸识别。在FERET、CAS-PEAL-R1、LFW东谈主脸数据库上的实考据明本文提议身手在是东谈主脸识别上具有优厚性。
