| 摘 要： | 提出了一种用于非均匀光照条件下人脸识别的光照补偿算法。该算法通过在对数域计算2维Armlets多小波变换来实现人脸光照补偿，然后直接在对数域进行人脸识别。在Yale B人脸库中与其他光照补偿算法进行了比较，实验结果表明，该方法的平均误识率仅为0.18%，优于现有的其他算法。

| Abstract: | A new illumination compensation method for face recognition under nonuniform illumination conditions was presented. The method calculated 2-dimensional Armlets (analysis-ready multiwavelets) transform for face illumination compensation in logarithm domain, and then conducted face recognition experiment directly in logarithm domain. The proposed approach was compared with other illumination compensation methods on Yale B face database. The experimental results show that the average error rate of the proposed approach is only 0.18%, which is superior to that of all the existing methods. |
