An adaptive video watermarking algorithm based on DCT and SVD
Mi Li · Microcomputer Information · 2009
In this paper, a blind adaptive video watermarking algorithm based on DCT ( discrete cosine transformation) and SVD (singular value decomposition) is proposed. The algorithm first partitions the video stream into several shots, And both the frames of the shots are transformed into DCT-SVD domain. the watermarking sequence is embedded into the largest singular value. Experiments showed the new algorithm meet the transparency requirements at the same time meet the requirements of a certain robustness, resistance to low-pass filtering, median filter, noise and H.264 compression, and Collusion, Cut-and-splice attacks.
