摘要
本文充分利用零水印的优点 ,提出了一种基于小波变换的数字图象水印算法。该算法在不改变原图象数据的同时 ,利用图象自身特点嵌入水印 ,在一定程度上缓解丁水印的鲁棒性与不可见性之间的矛盾 。
In this paper, a wavelet-based digital image watermarking algorithm is put forward,advantage of the zero watermark. This algorithm embeds water mark in to the area of image using the own characteristic of image, and it dose not modify the data of the original image. This algorithm can solve the contradiction between invisibility and robustness in some degree. It has been proved to have better invisibility and strong robustness to resist common image processing by experiment.
