Abstract
We present a watermarking procedure to embed copyright protection into video sequences. To address issues associated with video motion and redundancy, individual watermarks are created for objects within the video. Each watermark is created by shaping an author and video dependent pseudo-random sequence according to the perceptual masking characteristics of the video. As a result, the watermark adapts to each video to ensure invisibility and robustness. Furthermore, the noise-like watermark is statistically undetectable. The watermark also resolves multiple ownership claims. We demonstrate the robustness of the watermarking procedure to video degradations, e.g., those that result from noise, MPEG compression, cropping, and printing and scanning.
