Efficient Pixel Prediction Algorithm for Reversible Data Hiding
2016
International Journal of Network Security
Prediction-error expansion (PEE) is an important reversible data hiding technique, which can hide large messages into digital media with little distortion. In this paper, we propose a nearest neighborhood pixel prediction algorithm (NNP 2 ) for reversible data hiding algorithms based on Chinese Remainder Theorem (CRT), in which a rhombus prediction is applied in NNP 2 , and prediction errors, the difference between pixels and predictions, are modified to embed data. Further, CRT is utilized to
