摘要： 提出一种基于图象多尺度边缘的水印算法。利用常用于边缘检测的二进小波变换检测出图象的多尺度边缘,在选择出的重要多尺度边缘中嵌入数字水印。利用相关检测器进行水印检验检验过程需要原始图象。实验证明算法具有不可见性安全性对通常的图象处理有较强,,,的鲁棒性。

Abstract: A watermarking scheme based on the multi-scale edges of digital image is proposed in this paper. The multi-scale edges are characterized with the dyadic wavelets, which are usually utilized in irregularity or edge detection. The watermarks are embedded into important selected multi-scale edges. A correlation function is used in the watermark detection process and the original image is required. Experimental results show the watermark is invisible, secure and robust to common image processing operations.
