Robust Video Watermarking Algorithm Based on H.264
Quan Liu, Liu Hong · 2008
Video copyright protection is an important concern under the circumstances of network. A novel video watermarking algorithm is proposed according to the feature of DCT coefficients in I frame image on H.264. It generates watermark information using low frequency coefficients and embeds the watermark in middle frequency coefficients to make it robust and blind. This method needn't the original video when detecting the watermark. Results of experiment shows that this algorithm is real-time, imperceptible, blind and robust, thereby it can satisfy with the video watermark technology requirements.
