Adaptive Watermark Embedding in DCT-SVD Domain for Raw Video
This paper proposes an adaptive watermark embedding algorithm in the discrete cosine transform (DCT) and singular value decomposition (SVD) domain for raw video. The algorithm first segments video streams into scenes, transforms video frames into DCT-SVD domain, and quantizes watermark embedding on maximum singular values to achieve blind watermark detection. Experimental results demonstrate that the algorithm maintains transparency while resisting various attacks including low-pass filtering, median filtering, salt-and-pepper noise, Gaussian noise, H.264 compression, statistical attacks, and frame cropping.
