摘要
分析了目前常见的三种水印算法,并提出了一种基于小波变换的水印嵌入算法。编写了此算法的MATLAB仿真程序并进行仿真实验,还对算法的鲁棒性进行检验,实验结果表明,该算法鲁棒性较好,对噪声攻击都有一定的抵御能力。
Analyzed three kinds of common watermark algorithm,and proposed a watermark embedding algorithm based on wavelet transform.Simulated the algorithm and the algorithm ＇s robustness with MATLAB.The results show that,the algorithm has better robustness and have a certain ability to resist attack to noise.
