[Crack HackDWThundunjiami

Description: 文中提出了一种基于离散小波变换和混沌加密的数字水印新算法,采用二维混沌变换对水印图像加密 对载体图像进行多分辨离散小波变换,应用小波系数判断载体图像的纹理复杂程度后,依据人眼的视觉系统(HVS)特性,将水印信号嵌入到图像的低频部分,对图像的不 同分解层分别选取不同的纹理阈值和水印嵌入强度,将数字水印嵌入到相同分辨层的原始图像中,提高了水印算法的鲁棒性。在检测和提取水印时,通过水印相似度(NC)和峰值信噪比( PNSR)评价水印质量,实验结果表明提出的算法可以抵抗剪裁、JPEG压缩、滤波等几何攻击,算法简单,计算复杂度小,兼顾了水印的不可见性和鲁棒性。-err
