Reversible data hiding (RDH) with contrast enhancement (RDH-CE) is a special type of RDH in improving the subjective visual perception by enhancing the image contrast during the process of data embedding. In RDH-CE, data hiding is achieved via pairwise histogram expansion, and the embedding rate can be increased by performing multiple cycles of histogram expansions. However, when embedding rate gets ...

In prediction error-based reversible data hiding, multiple histograms modification (MHM) is well known for high image quality and thus has received wide attention in recent years. However, the computational cost for performance optimization in MHM is too high, which is particularly critical for real-time applications. This manuscript aims to reduce the computational complexity of MHM by presenting ...

Along with the popularization of high-speed internet and high-performance digital cameras, the consumption prosperity of high-resolution videos and pictures appears. However, high-performance cameras bring about content infringes through illegal videotaping, which greatly damages the privileges and benefits of the content owners. Multimedia forensics is one of the most important copyright protection ...
