- 基于小波零树特性的视觉感知度模型的优化方案, 给出了两种水印算法: 一种算法嵌入的是高斯序列水印, 通过相关检测实现盲检测 另一种算法嵌入的是二值图像水印, 水印的提取是非盲提取。这两种算法在所有重要小波系数( 包括最低频系数) 中嵌入水印, 以达到最大化水印嵌入量的目的, 并结合感知度模型在水印的透明性和鲁棒性之间实现了较好的平衡, 对于常见的图像处理操作, 特别是对于JPEG 和小波压缩均有较好的鲁棒性。-based on wavelet zerotree visual perception

- 数字水印文件和数字水印命令是数字水印技术在军事应用的两个重要应用。本文以一种基于分数阶傅里叶变换 (FRFT)的数字水印算法，使用chirp信号作为水印信息，嵌入到图像的分数阶傅里叶的加密域中。该算法有效地利用水印的 嵌入位置和FRFT的阶次作为密钥的同时，还利用chirp信号在分数阶傅里叶域的特点，可以很方便的检测到水印，具有良好 的不可见性和安全性的同时，还能够抵抗很强的JPEG压缩和噪声的攻击，对剪切、滤波等操作也有一定的鲁棒性。-Watermarking files and
