Human visual system has a limitation of sensitivity in detecting small distortion in an
image/video and the minimum perceptual threshold is so called Just Noticeable Difference …

In this paper, we show that a high-level of correlation exists between a simple image feature–
mean gradient magnitude and the peak signal-to-noise ratio (PSNR) of the first just …

Image quality assessment (IQA) plays a central role in many image processing algorithms
and systems. Although many popular IQA models achieves high performance on existing …

With explosive increase of internet video services, perceptual modeling for video quality has
attracted more attentions to provide high quality-of-experience (QoE) for end-users subject …

Abstract Machine visual intelligence has exploded in recent years. Large-scale, high-quality
image and video datasets significantly empower learning-based machine vision models …

Observer screening and subject opinion score recovery is essential for collecting a reliable
QoE database. This paper proposes a new method, ZREC*, which uses Z-scores to estimate …

With the develo** explosion in video data delivery, perceptual video coding (PVC) plays
an increasingly significant role in video compression. The just noticeable distortion (JND) …

The satisfied user ratio (SUR) curve for a lossy image compression scheme, eg, JPEG,
characterizes the complementary cumulative distribution function of the just noticeable …

This paper presents an approach for providing the desired visually lossless quality of Joint
Photographic Experts Group (JPEG) and Versatile Video Coding (VVC) compressed …

The Just Noticeable Difference (JND) refers to the smallest distortion in an image or video
that can be perceived by Human Visual System (HVS), and is widely used in optimizing …
