Abstract :
Unauthorized redistribution of a movie is a common threat to digital media that can be prevented by digital video watermarking. The watermark is commonly embedded into the luminance (Y) component of a video frame. The chrominance (U) component supports more distortion than the Y component without being perceived by human eyes. Thus, in our proposed approach, the watermark is embedded into the U component in each frame of a video sequence using the dual-tree complex wavelet transform (DT CWT). This approach aims to provide perceptually invisible high quality watermarked video. The watermark detection is performed without using the original video content, i.e., the watermark extraction is blind. The proposed scheme is robust against different geometrical attacks such as scaling, cropping and rotation as well as lossy compression.
