摘要: Recently, more importance is given to reversible data hiding (RDH) schemes because it restores original cover image without loss after the secret extracted and useful in authentication integrity checking. In this paper, a novel RDH scheme for digital images proposed that has high capacity with low distortion. The divided into blocks all pixels block are converted odd value or even by computing optimal of block. mean, median, max histogram min---max average which very nearer Secret directly embedded using property. receiving end, extracting can be recovered its form same value. tested several monochrome color images. experimental results reveal
