Reversible Data Hiding for JPEG Images Based on Histogram Pairs
This paper proposes a lossless data hiding technique for JPEG images based on histogram pairs. It embeds data into the JPEG quantized 8x8 block DCT coefficients and can achieve good performance in terms of PSNR versus payload through manipulating histogram pairs with optimum threshold and optimum region of the JPEG DCT coefficients. It can obtain higher payload than the prior arts. In addition,...
متن کاملStereo Image Coding with Histogram-Pair Based Reversible Data Hiding
This paper presents a stereo image coding method using reversible data hiding technique so that the right frame can be recovered losslessly and the left frame can be reconstructed with high visual quality. Utilizing the similarity between two frames in a stereo image pair the required size of storage and transmission bandwidth for the stereo image pair can be reduced to 50%. A residual error ma...
متن کاملReversible Data Hiding Based on Median Difference Histogram
This work proposes a reversible data hiding algorithm that is based on the median difference histogram. The method divides the cover image into non-overlapping identical blocks. In each block, the median pixel is selected to calculate absolute differences between the median pixel value and the values of the other pixels. Then, these differences are used to generate a histogram and the histogram...
متن کاملImproving histogram-based reversible data hiding by interleaving predictions
Data hiding is an important way of realising copyright protection for multimedia. In this study, a new predictive method is proposed to enhance the histogram-based reversible data hiding approach on grey images. In those developed histogram-based reversible data hiding approaches, their drawbacks are the number of predictive values less to the number of pixels in an image. In these interleaving...
متن کاملReversible Data Hiding with Prediction-based Histogram Alteration
In this paper, we propos e a new algorithm in reversible data hiding, with the applications of copyright and privacy protection for natural image s. Security issues for digital images have long been an important topic in research and practical applications, and reversible data hiding has attracted more and more attention. Unlike conventional schemes, we take the prediction of luminance values a...
