Digital watermarking techniques can be used to solve the authenticity and copyright
protection issue of images. In this work, the authors have proposed an adaptive color image …

The just noticeable difference (JND) measures the visual redundancy of digital images and
is widely used in signal processing. Conventional JND models attempt to simulate functional …

This paper proposes a robust and secure watermarking method for a color image in YC b C r
color space. In this study, watermarking is performed using Lifting Wavelet Transform (LWT) …

Most frequency-domain remote sensing image watermarking algorithms embed watermarks
at random locations, which have negative impact on the watermark invisibility. In this study …

The wireless transmission of patients' particulars and medical data to a specialised centre
after an initial screening at a remote health facility may cause potential threats to patients' …

The key problem of visible watermarking is how to balance the watermark visibility, the
security and the quality of marked image. In this paper, an adaptive visible watermarking …

Digital images have become an important way of transmitting information, and the risk of
attacks during transmission is increasing. Image watermarking is an important technical …

Digital image watermarking algorithms have been designed for intellectual property,
copyright protection, medical data management, and other related fields; furthermore, in real …

Aiming at the problem that the robustness, visibility, and transparency of the existing visible
watermarking technologies are difficult to achieve a balance, this paper proposes an …

Digital watermarking is an essential tool for numerous applications, and the quality of
watermarked images must be assessed using accurate criteria. Peak Signal-to-Noise Ratio …
