This paper proposes a high capacity reversible image watermarking scheme based on
integer-to-integer wavelet transforms. The proposed scheme divides an input image into …

Reversible contrast mapping (RCM) is a simple integer transform that applies to pairs of
pixels. For some pairs of pixels, RCM is invertible, even if the least significant bits (LSBs) of …

Reversible data embedding is a very important issue, especially in dealing with sensitive
images such as military data and medical data. Based on the edge-directed prediction …

This manuscript considers the distinct prediction error expansion (PEE) of each pixel up to
the limit of overflow/underflow in view of embedding a maximum amount of data. A moduli …

With the aim of reducing the distortion of traditional partitions, this paper investigates a novel
method that partitions every square region into 2 n nesting sub-regions. Based on the …

Reversible contrast mapping (RCM) and its various modified versions are used extensively
in reversible watermarking (RW) to embed secret information into the digital contents. RCM …

Digital watermarking has an important application to protect and authenticate the medical
images. To perform accordingly one of the most commonly used methods is region based …

This paper investigates the distortion-free robust watermarking by multiple marking. Robust
watermarking is first performed. Then, by reversible watermarking, the information needed to …

This paper analyses and rectifies the shortcomings of reversible contrast mapping (RCM)
algorithm for invisible watermarking. The proposed corrected RCM algorithm is tested by …

The classical difference expansion (DE) reversible watermarking expands two times a
difference in order to embed one bit of data. The upper limit of such DE schemes in a single …
