Firstly, to ensure the security of wartermark,the wartermark image is Arnold scrambled before embedding and expanded to the twifold size of the original image.The corresponding subband data of the watermark and the red,green,blue weight for original image are combined according to the characteristic of the multiresolution decomposition of the wavelet transform.

首先，为保证水印的安全性，在嵌入之前先对水印图像作Arnold置乱处理，再将水印图像位扩展为原始图像的两倍大小；然后根据小波变换的多分辨率分解特性，将位扩展水印和原始彩色图像红色、绿色、蓝色分量对应方向上的子带系数进行组合。

First, face image is decomposed by two dimension wavelet transform. Then the low frequency subband is convolved with Gabor filters and downsampled by a factor. After that, the kernel principal component analysis is used to reduce the dimension of Gabor features. Finally, minimum distance classifier is used to classify.
