In the past two decades, reversible data hiding (RDH), also referred to as lossless or
invertible data hiding, has gradually become a very active research area in the field of data …

Medical images can be intentionally or unintentionally manipulated both within the secure
medical system environment and outside, as images are viewed, extracted and transmitted …

Reversible data embedding has drawn lots of interest recently. Being reversible, the original
digital content can be completely restored. We present a novel reversible data-embedding …

Digital audio, video, images, and documents are flying through cyberspace to their
respective owners. Unfortunately, along the way, individuals may choose to intervene and …

Watermarking embeds information into a digital signal like audio, image, or video.
Reversible image watermarking can restore the original image without any distortion after …

Reversible watermarking enables the embedding of useful information in a host signal
without any loss of host information. Tian's difference-expansion technique is a high …

We present a novel lossless (reversible) data-embedding technique, which enables the
exact recovery of the original host signal upon extraction of the embedded information. A …

Despite the continuous advances in local stereo matching for years, most efforts are on
developing robust cost computation and aggregation methods. Little attention has been …

With the increasingly widespread use of medical images in medical institutions and
networks, the copyright protection of medical images has become increasingly urgent. Since …

In this letter, we present a reversible data hiding scheme based on histogram modification.
We exploit a binary tree structure to solve the problem of communicating pairs of peak …
