DWT域基于位平面的图像公开水印算法

A Public Image Watermarking Algorithm Based on the Bit Planes in the DWT Domain

本文提出了一种新颖的DWT域公开水印算法,该算法基于位平面的思想,在小波逼近子图的分解子图中结合HVS的特性多版本嵌入二值水印图像信息,最后基于统计的原理提取水印。实验表明,此算法效率高,鲁棒性、透明性好。

A new public watermarking algorithm in the DWT domain is presented. Based on bit planes, the binary water- marking information is embedded during wavelet decompositions by using the characteristics of HVS, and is detected using statistical tools. Experimental results show that the proposed scheme is efficient, robust and transparent.
