Adaptive reversible data hiding based on block median preservation and modification of prediction errors
چکیده انگلیسی


• We propose two enhanced schemes whose simulation results are better than the original ones.
• The enhanced schemes will adopt different steps according to the payload required.
• We compare the proposed schemes with other promising reversible data hiding schemes, where the simulation results are satisfied.

In this paper, two enhanced reversible data hiding methods are proposed; both of them are based on two novel reversible data hiding techniques. A latest predictor is adopted to achieve better data hiding capability for the first predicative reversible data hiding scheme, whereas another scheme utilizes a new approach by considering the nature of different images to classify the smoothness for each piece of image blocking regions such that more secret data can be hidden into the smooth regions rather than the non-smooth ones resulting in a better embedding capability. The experiments verify that these schemes outperform the original reversible data hiding algorithms and some state-of-the-art reversible data hiding schemes.
