Improving the perceptual quality of images is challenging for the robust watermarking
method. To address this problem, most existing algorithms proposed to guide the watermark …

The human visual system (HVS) is a hierarchical system, in which visual signals are
processed hierarchically. In this paper, the HVS is modeled as a three-level communication …

Just noticeable distortion (JND), reflecting the perceptual redundancy directly, has been
widely used in image and video compression. However, the human visual system (HVS) is …

Image pattern classification is considered a significant step for image and video processing.
Although various image pattern algorithms have been proposed so far that achieved …

A novel block‐level perceptual image watermarking framework is proposed in this study,
including tri‐directional correlation and a block‐level just noticeable difference (JND) model …

The just noticeable difference (JND) reveals the key characteristic of visual perception,
which has been widely used in many perception-based image and video applications …

As one of the most studied areas, telemedicine allows doctors and pathologists to share
their intelligence all over the world. To achieve the highest efficiency of remote pathology …

Generally speaking, those watermarking studies using the spatial domain tend to be fast but
with limited robustness and imperceptibility while those performed in other transform …

Screen content video (SCV) consists primarily of text areas, computer graphics and other
computer‐generated content and possesses unique perceptual characteristics. To compress …

Abstract The Just Noticeable Distortion (JND) threshold refers to the inability of the human
visual system (HVS) to perceive pixel changes below a certain visibility threshold. In this …
