Reversible image data hiding based on gradient adjusted prediction
The present study illustrates a new lossless data hiding method for digital images using image prediction technique. In the proposed method which is based on gradient-adjusted prediction (GAP), first prediction errors are computed and then the error values are slightly modified through shifting the prediction errors. The modified errors are used for embedding the data. Experimental results of p...
متن کاملPrediction-based reversible data hiding
For some applications such as satellite and medical images, reversible data hiding is the best solution to provide copyright protection or authentication. Being reversible, the decoder can extract the hidden data and recover the original image without distortion. In this paper, a reversible data hiding scheme based on prediction error expansion is proposed. The predictive value is computed by u...
متن کاملReversible Data Hiding Based on Histogram by Using Gradient Adjacent Prediction
In this paper, we use gradient adjacent prediction to present a new data hiding method based on histogram. Our method can increase the amount of hidden data, and keep higher PSNR of stego-image. According to experiment results, our method increases the amount of hidden data by 12.5% on the average as compared with Jang et al.’s method.
متن کاملReversible Data Hiding Based On H.264/AVC Intra Prediction
This paper proposes a novel high capacity reversible image data hiding scheme using a prediction technique which is effective for error resilience in H.264/AVC. In the proposed method, which is based on H.264/AVC intra prediction, firstly the prediction error blocks are computed and then the error values are slightly modified through shifting the prediction errors. The modified errors are used ...
متن کاملEfficient Reversible Data Hiding Algorithms Based on Dual Prediction
In this paper, a new reversible data hiding (RDH) algorithm that is based on the concept of shifting of prediction error histograms is proposed. The algorithm extends the efficient modification of prediction errors (MPE) algorithm by incorporating two predictors and using one prediction error value for data embedding. The motivation behind using two predictors is driven by the fact that predict...
