【摘要】 提出一种改进分形数字水印算法,对传统的分形数字水印进行改进,利用混沌序列对水印图像进行置乱处理,增强了水印的鲁棒性。实验结果表明,该算法具有较好的鲁棒性,而且对高斯噪声以及剪切等都有良好的稳健性。更多还原

【Abstract】 Proposes a fractal watermarking algorithm,it improve the traditional fractal digital watermarking,applies chaotic sequence transform to the watermark sequence,enhances the robustness.Experimental results show that the algorithm not only has good robustness,but also resists some kinds of transform such as Gaussian noise and clipping.更多还原
