摘要
本文提出了一种结合人眼视觉特性(HVS)的自适应水印嵌入方法的基于最优小波包基数字图像水印鲁棒性算法。通过Matlab的仿真程序对水印图像进行JPEG压缩、剪切、加噪声、滤波等多种攻击实验后,仍然可以提取较为清晰的水印,从而得出该算法较小波变换水印算法具有更好的鲁棒性结论。
In this paper, we present a novel robust digital image watermark arithmetic based on Wavelet Packet With Best Tree with combining HVS and embedding method of image adaptive. After jepg compress, crop, noises and filters attacks from MATLAB emluator, we still extract a visible watermark. According to the results, we can draw a conclusion that this arithmetic is better robust than digital image watermark arithmetic based on Wavelet Transform.
