Abstract: Aiming at the problem that the robustness of the existing anti-remake attack watermark is not enough to resist the new type of remake attack and the transparency is not good, an adaptive watermarking algorithm based on AKAZE operator is proposed by introducing the adaptive idea. Firstly, the AKAZE operator is used to locate the key points, and then a preliminary screening is made for the key points according to the distance between the key points and the distance to the image frame, and then a mapping is constructed between the entropy value of the filtered key point neighborhood, the watermark embedding strength and the average similarity before and after embedding. After the mapping is constructed, the key points can be adaptively filtered only according to the entropy value of the image block, and the appropriate embedding rate of the key point neighborhood after the secondary screening is obtained, Finally, the watermark is embedded in the filtered key point neighborhood using singular value decomposition. The experimental results show that this watermarking algorithm has excellent robustness while maintaining good imperceptibility, which is significantly improved compared with the existing anti-screen-shooting attack watermark.
