摘要 文章将局部二值模式(LBP)引入到图像预处理中,以期利用LBP的性质,克服光照变化对人脸识别的影响.为进一步利用LBP模型的性质,提出一种称之为二阶LBP的新型算子并应用于人脸识别.实验结果表明,二阶LBP模型在克服光照变化上性能优于LBP模型. The LBP model is introduced into the image preprocessing. Experimental results show that the LBP model is superior to the histogram specification in illumination preprocessing. A new facial feature extraction operator called second order LBP is presented, and its properties are discussed. Test results show that the second order LBP is better than the LBP in terms of the lighting changes
