Improved PVO-based reversible data hiding: A new implementation based on multiple histograms modification
Abstract: Highlights•An improved pixel-value-ordering (PVO) based reversible data hiding based on multiple histograms modification (MHM) is proposed.•The new algorithm is considered in a framework that is based on MHM and parameterized by the selection of expansion bins.•The proposed MHM determination is a methodology of adaptive histogram modification, and is applicable for the existing techniques of histogram generation.
