| 摘 要： | 光照变化条件下的人脸图像识别一直以来都是图像处理中的热点和难点问题,为了提高人脸图像的识别率,提出了一种用于非均匀光照条件下人脸识别的算法.利用对数及二维小波变换的多尺度特性提取出人脸的光照不变量,然后运用PCA+LDA方法进行人脸特征提取,并采用基于欧氏距离的最近邻分类器进行识别.通过Matlab编程实验,在Yale B人脸库中达到了较高的识别率.

| Abstract: | Illumination variation is the most significant factor affecting the performance of face recognition,and has received much attention in recent years.A novel method to extract illumination invariant features was proposed for face recognition under varying lighting conditions,which combined wavelet transform and logarithm operation.The experiment with Matlab programs was designed on Yale B face database by PCA+LDA recognition.Minimum distance classifier was applied for its simplicity;the Euclidean metric L2 wa... |
