| 摘 要： | 本文主要利用混沌算法和小波分解实现数字图像的水印处理。首先,利用混沌算法对水印数字图像进行置乱,然后,将置乱后的水印嵌入到小波分解后的宿主图像里面。通过实验证明,该算法对常见的信号攻击和几何剪切攻击均具有较好的鲁棒性。

| Abstract: | This paper mainly used chaos algorithm and wavelet decomposition method to implement digital image watermarking process.Firstly,the watermarking digital images are scrambled by using the chaos algorithm,and then,the scrambled watermark digital images will be embedded into the image which is broken down by the wavelet decomposition.The experimental results show that the algorithm has good robustness for common signal attack and cropping attacks. |
