JPEG Reversible Data Hiding with Matrix Embedding

2019
Joint photographic experts group (JPEG) image is the most popular image format used in our daily life. Different from the reversible data hiding (RDH) in spatial domain image, JPEG RDH needs to consider not only the visual quality, but also the file storage size of the marked image.

Reversible data-hiding for progressive image transmission

Signal Processing: Image Communication, 2011
This research presents a multi-resolution reversible data-hiding algorithm to enable multi-scale marked images that are transmitted progressively to be exactly recovered at the receiver side once hidden data has been extracted. Based on the spatially hierarchical multi-layer structures of progressive-image transmission, the proposed algorithm first ...

Reversible Data Hiding With Optimal Value Transfer

IEEE Transactions on Multimedia, 2013
In reversible data hiding techniques, the values of host data are modified according to some particular rules and the original host content can be perfectly restored after extraction of the hidden data on receiver side. In this paper, the optimal rule of value modification under a payload-distortion criterion is found by using an iterative procedure ...
