摘要
提出了一种抗JPEG压缩的零水印算法,用以保护图像版权。目前,大多数算法通过修改原始图像的数据来嵌入水印,这类水印算法在拥有抗压缩能力的同时,也破坏了原始图像的视觉效果。而本文算法是一种零水印算法,既保证了原始图像的完好性,又利用容错区间有效地抵抗了压缩攻击。
A zero-watermarking algorithm resisting JPEG compression is proposed in this article , which is used to protect im-age copyrights . Currently , most of algorithms embed watermark into the original image by modifying its data . With the capacity of anti compression , this kind of watermarking algorithms destroy the visual effect of original images . But the algorithm in this paper is a zero watermarking algorithm , which ensures the integrity of the original image , and the fault-tolerant intervals resist compres-sion attacks effectively .
