A Robust Video Watermarking Scheme Through Motion-Frame Extraction and DWT-SVD Approach
摘要
The blistering development of the multimedia sharing by Internet has increased the worries about the copyright protection and the unauthorized distribution of the video materials. Conventional approaches to watermarking can be difficult to stay strong and aesthetics-nonintrusive to compression, noise, geometrical distortions, or frame-specific watermark attacks. The proposed paper presents a hybrid video-watermarking technique that controls such shortcomings by embedding encrypted and scrambled watermarks into specific motion frames and making use of the Discrete Wavelet Transform (DWT), Singular Value Decomposition (SVD), and guided filtering. Placing the watermark in motion-intensive frames will reduce the perceptual effect and increase the protection to illegal interference. The proposed scheme is proven to be imperceptible and also strong in numerous tests performed under geometric attacks, noisy attacks, frame-based attacks, and in resisting signal-processing attacks, as well as, video based attacks when compared with the existing methods. In this regard, it provides a safe and effective means of copyrighting the digital video.
