文章在小波分析的基础上，提出了一种在图像的小波分解数据域中实现对称变换的方法，

并把这种方法运用于人脸特征的定位，这种方法可以提高人脸特征定位的效率。-Based on wavelet analysis, the article proposes a wavelet decomposition of the image data domain symmetry transformation method, and this method is applied to the positioning of the facial feature, this method can improve the efficiency of the facial features localization .
