Abstract: This paper presents a novel watermarking algorithm of MPEG video based on visual features. An effective mixed feature model of the block is delicately designed by texture,luminance and motion features of the video.According to the perceptual features derived from the masking behavior of the human perceptual model,a feature statistics model is introduced to adjust the extracted block feature,and then the copyright protection is embedded into the block according to the modified block feature.Experimental results show that the watermarked video is highly imperceptible and resistant to many degradations and distortions of video,especially the colored noise,coding and temporal processing.
