| 摘 要： | 利用小波变换多分辨率特性和人眼视觉特征,提出了一种彩色图像多水印算法.多个有意义的签名水印能提供更可靠的版权识别,而且多水印相互配合使水印图像同时具有很好的鲁棒性.为增强水印的鲁棒性,在添加水印之前对水印进行预处理,在嵌入水印时又应用了扩频技术.实验结果表明,该算法取得了良好的效果.

| Abstract: | Taking advantages of the multiresolution feature of wavelet transform and the property of human visual system,a color image accreditation algorithm by embedding multi-signature watermarks in image is presented here.Multi-watermarking system can be a valid way of ownership identification and can achieve total robustness.In order to increase the robustness of watermark,we preprocess the watermark using Chaos Technology and Spread Spectrum Method while watermark is embedded into Image.Experiment shows this method has a good result. |
