摘要

Digital watermarking technique has been developed for many years, various kinds of algorithms in frequency domain has being become more and more important because of their good robustness. But, in these methods, the position where the watermark was embedded must be known before detecting and extracting the watermark, they can not satisfy the robustness of geometry attacks such as cropping. In this paper, we propose a new image watermarking algorithm based on some new techniques such as labeling the watermarks position, image patching, and solve these problems. Experimental results show the algorithm we proposed here is very effective.
