Perceptual quality assessment plays a vital role in the visual communication systems owing
to the existence of quality degradations introduced in various stages of visual signal …

360-degree images/videos have been dramatically increasing in recent years. The
characteristic of omnidirectional-view results in high resolution of 360-degree …

360-degree/omnidirectional images (OIs) have received remarkable attention due to the
increasing applications of virtual reality (VR). Compared to conventional 2D images, OIs can …

The free energy principle was proposed several years ago as a unified justification for some
brain theories. The process of human perception, cognition, action, and learning can be well …

Low-light images, which are usually taken in dark or back-lighting conditions, are hard to
perceive due to the low visibility and low contrast. To improve viewers' Quality of Experience …

Multi-level deep-features have been driving state-of-the-art methods for aesthetics and
image quality assessment (IQA). However, most IQA benchmarks are comprised of artificially …

Assessing the visual quality of super-resolution images (SRIs) is crucial for advancing
algorithm development, but it remains an unsolved problem. In this paper, we present a …

In submarine and underwater detection tasks, conventional optical imaging and analysis
methods are not universally applicable due to the limited penetration depth of visible light …

Abstract Light Field Image (LFI) can simultaneously record the intensity and direction
information of light rays, and provide users with strong immersion experience. However …

In this paper, we put forward the concept of comparative perceptual quality assessment (C-
PQA), which refers to the judgment of relative qualities of two visual signals of the same …
