【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。更多还原

【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.更多还原
