| 摘 要： | 提出一种同时对水印信息和载体信息进行小波变换的方法,根据HVS模型把水印信息DWT变换后的系数嵌入到图像载体DWT系数中.实验表明,该方法达到视觉的隐蔽性,同时在抵抗JPEG压缩、滤波、噪音等方面都得到较好的效果.

| Abstract: | Present a method to process DWT against watermark and image information at the same time, embeds DWT-transformed coefficient of watermark information into DWT coefficient of image carrier based on HVS model. Experiment shows, the method of watermarking can guarantee transparency and has a good result of robustness to JPEG compression , filter and noise. |
