使用置乱技术和DCT变换的小波域数字水印

Digital Watermarking Based On Shuffling Techniques And Wavelet Transform

本文提出了一种基于小波域的数字水印方案。在嵌入图像之前,对水印进行置乱处理,对图像的小波系数使用离散余弦变换。实验证明,这种方法对常规图像处理有很好的鲁棒性。

A digital watermarking method based on Shuffling Techniques And Wavelet Transform is proposed in this paper. The image will be changed by DCT firstly . Before embedded into the lower frequency DWT coefficient of the image , the watermarking will obtain an Arnold transform. It is proved by experiment, this method possesses strong robust.
