摘要：

A new video watermarking scheme is proposed to resist object manipulations. Shape-adaptive DCT and a visual mask were combined to embed the shuffled watermark into the arbitrarily-shaped object. Inertia ellipse was employed to achieve fast self-synchronising watermark detection. Experiments show that the algorithm is robust to geometrical attacks.
