摘    要:提出了一种基于DWT多分辨率分解的数字水印技术.利刚多分辨率分解技术,分别将原始图像与水印图像进行三层离散小波变换,将相同分辨率层次水印嵌入到对应的相同分辨率层次的原始静态图像之中,使水印对原始图像具有自适应性.实验结果表明,本文提出的水印技算法经某些图像处理操作和JPEG压缩后仍是鲁俸的.

关 键 词:版权保护  数字水印  离散小波变换  峰值信噪比

Abstract:A digital watermarking technique based on multi-resolution decomposition is proposed.By multi-resolution decompositon technique,the 3-level DWT is applied to the host image and the watemark respectively firstly.The decopmposed watermarks of different resolution are embedded into the corresponding resolution of the decomposed original image,which makes the watermark be adapted to the original image.Experimental results show that the proposed technique is robust to some image processing operations and Joint Photographic Experts Group(JPEG) compression.
Keywords:copyright protection  digital watermark  discrete wavelet transform  PSNR
