| 摘 要： | 结合二值水印图像的特点,运用海明码的监督关系式,首次提出了一种基于海明码的像素级数字水印检测方法.在认证检测时,仅利用一幅与水印图像内容毫不相关的检测图,通过异或运算操作就可以准确确认某像素点是否被篡改,并具有篡改定位与修复能力,省略了一般水印检测方法的图像匹配、逆变换与相似计算等复杂操作.

| Abstract: | Based on the characteristics of the binary image,we present a digital watermark authentication method with the supervisory relationship of Hamming Code.By generating a watermark detection map,we can accurately confirm whether a certain pixel point is altered without the original watermark,and tamper with the positioning and repairing capacity.Compared with the general detection method,this method is more flexible in that it skips such complicated processes as image match,inversion exchange and similar calcu... |
