Reversible data hiding based on multilevel histogram modification and pixel value grouping

Abstract

This paper proposes a multilevel histogrammodification based reversible data hiding scheme using a new difference generation strategy called pixel value grouping (PVG). It aims to produce shaper difference histogram by exploiting the high correlation among pixels within block. After sorting, pixel values are grouped according to their distribution. For each… (More)
