基于异或运算和图像融合的盲数字水印嵌入和检测方法

A Way of Blind Watermarking Embedding and Detection Based on XOR and Amalgamation

数字水印隐藏是将一个版权识别标志(水印信号)嵌入到图像中的技术。本文提出的一种新的隐藏水印的方法是将水印看作是二值图像,运用小波变换,异或运算,图像融合的方法以及中值滤波来隐藏和提取数字水印。这种方法的优点是不需要原始图像就可以提取出水印图像,可以加密码,对椒盐噪声,剪切攻击具有鲁棒性。

Digital watermarking is a technique for labeling digital pictures by hiding copyright information into images. A new method is proposed . The watermark is processed as a pattern-binary image.The watermarking is hided and extracted with DWT transformation ,XOR operation ,image amalgamation and median filter .The merit of the method is not only that the watermarking is extracted without original image ,but also that it can be encrypted, and it is robust to the salt and pepper noise and cropping.
