There exist various video watermarking schemes to protect copyrighted video content. Since most of these schemes exploit the perceptual properties of an original video content, they ineludibly had high computing complexity to embed watermark. However, some video applications such as settop box (STB) don't have enough computing power to insert the watermark into the high definition (HD) content using...
This paper proposes a composite mask based watermarking method, which improves perceptual quality of videos watermarked by traditional video watermarking scheme. The composite mask including noise visibility function (NVF) mask, adaptive dithering mask, and contour mask considers human visual system (HVS). The adaptive dithering mask solves the block artifact problem caused by expanding the watermark...
