Abstract:A video watermarking method is described that takes into account the human visual system for processing color information to maintain picture quality better than a previously reported watermarking method. The improved method determines the watermark strength in the L*u*v* space, where human-perceived degradation of picture quality can be measured in terms of Euclidean distance, and embeds and detects watermarks in the YUV space, where detection is more reliable than that in the original method. Experimental ev… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
