Abstract

A method of embedding a digital watermark image in video is proposed in this paper. By two-dimensional and three-dimensional multiresolution signal decomposing, the decomposed watermark images with different resolution are embedded in the corresponding resolution of the decomposed video. To enhance the robustness of watermarking, the watermark information is coded by error correction coding of Hamming code in our algorithm. Experimental results show that the proposed technique is robust enough against the attacks of frame dropping, averaging and lossy compression
