基于直方图交核的人脸识别

摘要

Profile Histogram Intersection （PHI） kernels and Detail Histogram Intersection （DHI） kernels function are proposed based on traditional Histogram Intersection kernels. Experiments on ORL and YALE databases show that DHI kernel achieves higher accuracy than that of HI kernel.%基于传统直方图交核（HI）提出了轮廓直方图交核（PHI）以及局部直方图交核（DHI），并将这2种核用于ORL和YALE人脸库的识别．实验结果表明，构造的局部直方图交核（DHI）比那些传统的直方图交核获得了更高的识别率．
