| 摘 要： | 提出了一种基于小波变换的图像加水印及检测的新方法,即对图像文件进行二维多尺度离散小波变换,得到图像数据高频和低频部分。在高频部分数据中,加入随机数水印并进行图像重构,检测时以同样方法进行小波分解,检测高频部分与随机数水印的相关性。此方法可用于图像防伪。

| Abstract: | This paper introduces a method of watermark processing and back-check based on wavelet transform. When an image is processed by a multi-scale 2-dimension dispersed wavelet transform, the information can be divided into two parts: the low frequency part and the high frequency one. The image is reconstructed by adding some stochastic watermarks to the high frequency part. The checking can be achieved by comparing the cross correlation between the stochastic watermarks and high frequency information with the same wavelet transform as used. This method can be used to identify the image forgery. |
