An Image Watermarking Scheme Based on Local Feature Adaptive Filtering

Zhang Xing, Liu Shuai


This article is about a watermarking algorithm that based on adaptive filtering of local property, which is for verifying copyright information of images; this method is relies on a model of image degradation and restoration. The algorithm assumes that the degradation parameters of electronic equipment to be known, firstly, using the image binarization automatically generate digital watermarking signal; in addition, according to the characteristics of image noise, to use the image degradation / adaptive filtering algorithm that based on local feature restoration model of embedding and extracting watermark signal to the host image; finally, verify the proposed algorithm with experiments. In view of the experimental results, it reveals that the algorithm has good invisibility and robustness.


Image degradation / restoration; adaptive filtering local feature; digital watermarking.
