• W2956160125 abstract "Recent pixel value ordering (PVO) based development of reversible data hiding (RDH) schemes highly relies on an effective prediction error expansion (PEE). A prediction error is usually expanded either by embedding a bit in it or by shifting it by a “suitable” value. With PVO, this expansion is made directional, ı.e., left-ward, right-ward or both centering a reference pixel. This PVO property leads us to investigate that once a set of original pixels are expanded upon their predicted errors in one level of embedding, can that expansion be counterbalanced in an additional level of embedding? In this paper, we attempt to address this question in developing a new RDH scheme with PVO and classic PEE. An input image is partitioned into a set of non-overlapping blocks of size (1times 3). Data-bits are embedded into the blocks in two phases of embedding. Our early results have demonstrated that the counterbalance of expanded errors is possible to offer better embedding rate-distortion performance than the original baseline scheme. Future endeavor on generalizing the proposed scheme and its information theoretic analysis may create a new avenue in data hiding research." @default.
