DESIGN OF A DIGITAL WATERMARKING SCHEME BASED ON H.264/SVC
摘要
Abstract
Scalable video coding and watermarking technology is the research focus of multimedia applications and copyright protection at present. The paper proposes a video watermarking scheme based on DCT coefficients in combination with key control in light of H. 264SVC scalable video compression coding, the joining of key enhances the security. After pre-processing, the watermark bits are embedded into DCT coefficients, of which the proper positions are selected on the basis of HVS theory in conjunction with keys. The watermarks are embedded while the video is coding, and the detection is blind. Moreover, the multi-layer structure of spatial resolution of SVC video is made-use to enlarge the embedding capacity and strengthen the robustness. Experimental result shows that the scheme reaches good effect in both imperceptibility and robustness and is also able to resist some noises and attacks.关键词
