| 摘 要： | 介绍了图像水印技术目前所采用的主要算法及其各自的优缺点,归纳了成功的图象水印方案必须解决的关键问题。本文提出了一种基于小波变换域的自适应图象水印算法。算法先对原始图象进行3D-DWT,并对低频子带进行小波块的划分,据小波块的分类结果自适应地调整嵌入水印的强度。

| Abstract: | The main algorithms and their merits and shortcomings of video watermarking technology are introduced here. And then induced the key questions which a perfect image watermarking algorithm must solve. This article proposed a new adaptive image watermarking algorithm based on the DWT. This algorithm first carry out 3D digital wavelet transformation coefficients of primitive image, then divide the low frequency into wavelet block . At last adjusts insert watermark information with different intensity according... |
