摘要 提出了一种基于复数小波域的2维矢量图形的水印算法,用于2维矢量图形的版权保护。该算法利用了DualTree复数小波变换的优点,将水印嵌入相对坐标线(relativecoordinatesline)的复数小波域中。经初步实验结果验证,该算法对于通常的图形几何变换,如平移、旋转、缩放以及局部修改攻击,均有令人满意的鲁棒性。 This paper presents a new method of digital watermarking of 2D vector graphics to protect its authority. The watermark is embedded in the complex wavelet domain of relative coordinates line. Robustness to some common manipulations, such as translation, rotation scaling and local modification, have been proved by preliminary experimental results.
