A survey of reversible data hiding schemes based on two-dimensional histogram modification

Abstract

In recent years, in addition to one-dimensional reversible data hiding many two-dimensional histogram modification methods have been proposed. In this paper, various two-dimensional histogram modification reversible data hiding method are studied, analyzed, and compared, providing useful information for researchers in this field. The analysis and comparison of these include two-dimensional histogram modification reversible data hiding methods based on: difference-pairs, pairwise prediction error expansion, and PVO and pairwise prediction error expansion.
