Visual quality evaluation has numerous uses in practice, and also plays a central role in
shaping many visual processing algorithms and systems, as well as their implementation …

In region-of-interest (ROI)-based video coding, ROI parts of the frame are encoded with
higher quality than non-ROI parts. At low bit rates, such encoding may produce attention …

In image and video processing field, an effective compression algorithm should remove not
only the statistical redundancy information but also the perceptually insignificant component …

We propose a rate-distortion optimization (RDO) scheme based on the structural similarity
(SSIM) index, which was found to be a better indicator of perceived image quality than mean …

This paper proposes a new exposure fusion ap-proach for producing a high quality image
result from multiple exposure images. Based on the local weight and global weight by …

Traditional video compression methods remove spatial and temporal redundancy based on
the signal statistical correlation. However, to reach higher compression ratios without …

In this paper, we introduce a novel just noticeable difference (JND) estimation model based
on the unified brain theory, namely the free-energy principle. The existing pixel-based JND …

Just noticeable difference (JND) of natural images refers to the maximum pixel intensity
change magnitude that typical human visual system (HVS) cannot perceive. Existing efforts …

In this paper, we propose an effective approach to infer the just noticeable distortion (JND)
profile based on patch-level structural visibility learning. Instead of pixel-level JND profile …

Just-noticeable distortion (JND), which refers to the maximum distortion that the human
visual system (HVS) cannot perceive, plays an important role in perceptual image and video …
