| 摘 要： | 对原始人脸图像进行适当的预处理后，分别利用两种不同序的二维Walsh变换与神经网络相结合进行人脸识别，大大提高了识别的效率和效果．并且对两种序的效果进行了比较，发现在人脸图像的处理中逆Walsh序的二维Walsh变换比常用的Walsh-Hadamard变换略好．

| Abstract: | After the proper pre-processing, the recognition rates and effects of human face by combining the two-dimensional Walsh transform and the neural network were improved. Two kinds of orderings were compared. It was shown that the two-dimensional Walsh transform with the inverse Walsh ordering made energy more focused and the recognition rates higher than the Walsh-Hadamard transform. |
