Using NAMS (Negotiating Agents and Marital Stability), a couple who is considering marriage is aided in evaluating their compatibility. Using a vector of fundamental emotions, our algebra of emotion allows us to model self-generating emotions (such an interest or anger), have history-sensitive interactions, and accommodate gender differences.
An enhanced image quality for Distortionless Data Hiding (DDH) by Discrete Cosine Transform in images encrypted was implemented in this work. The DDH is commonly called reversible data hiding (RDH), referred as technique recovering input image with no distortion from stego image by separating the concealed information. Information can be implanted into the encrypted pictures by creating vacant space after encryption or before encryption. The former has the disadvantage of image degradation by data separation as well as on image recovery. To overcome the disadvantage, creating a vacant space before encryption such that it can attain real reversibility i.e. information can be separated from the cover picture with no degradation. Experiments result in a larger amount of data up to 1,31,072 bits embedded with better PSNR value in comparison to existing technique.
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.
