In this paper, a novel lossy image compression scheme suitable for fast window query which is based on Hilbert curve and VQ is proposed. It allows us to perform window query directly on the compressed code of a gray-level image without decompressing the full compressed image first.The compression effect achieved by our method is also excellent. According to the substantial experimental results, the applicability of our method can be demonstrated.
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.
