This scheme describes a procedure that uses the motion characteristics of the videos to calculate the embedding tolerance for imperceptible video watermarking in wavelet domain. This procedure exploits the perceptual properties of HVS and motion content of video sequence adoptively calculating the embedding tolerance of watermark in order to improve the imperceptibility of watermarking according to the content of video. The experiment results indicate that this method can effectively reduce the degradation in the video quality.
