摘要
数字水印技术通过在媒体图像中隐藏信号来达到保护版权的作用。本文利用二维离散整数小波变换的快速性,结合人类视觉系统特性,提出了一种基于彩色图像新的、简单的鲁棒性盲水印技术,实现了在彩色图像中嵌入有意义的二值图片。通过分析实验结果,证明了算法满足水印的抗JPEG压缩攻击、对原图的影响较小等特点。
Digital watermarking technique has been presented as a new method for copyright protection by embedding a secrete signal in a media image. A digital watermarking technique is proposed, utilizing the speediness of two-dimensional discrete wavelet transforms that map integers to integers and combining characteristic of the human＇s optical system. The method is for color images watermark and realized embedding meaning two-value photograph in color image. Experimental results prove that the proposed technique is robust to JFEG compression attacks and have little impress to the original photograph.
