| 摘 要： | 结合整数小波变换无舍入误差、完全可逆的优点,提出了一种将彩色水印图像嵌入到彩色载体图像的水印算法,水印信息先嵌入到低频系数中,如有剩余再嵌入到高频系数中,而嵌入公式根据系数所处的频带不同而不同,最后从理论上对算法进行了性能分析.实验结果表明:该算法具有透明性好、嵌入容量大,嵌入效率高等特点,并且对常见的攻击具有鲁棒性.

| Abstract: | Using the advantages of full reversibility and no rounding error of integer wavelet transform,a watermarking algorithm in which a color watermark image is embedded into a color host image is proposed.The watermark is embedded into low frequency coefficients firstly,and then any remaining is embedded into the high-frequency coefficients.According to the different coefficients of the frequency band,the embedding formulas differ.Finally the performances of the algorithms are analyzed in theory.Experiment resul... |
