A Survey on Perceptually Optimized Video Coding
Yun Zhang, Linwei Zhu, Gangyi Jiang +2
To provide users with more realistic visual experiences, videos are developing in the trends of Ultra High Definition (UHD), High Frame Rate (HFR), High Dynamic Range (HDR), Wide C…
A user model for JND-based video quality assessment: theory and applications
Haiqiang Wang, Ioannis Katsavounidis, Xinfeng Zhang +2
The video quality assessment (VQA) technology has attracted a lot of attention in recent years due to an increasing demand of video streaming services. Existing VQA methods are des…
A JND-based Video Quality Assessment Model and Its Application
Haiqiang Wang, Xinfeng Zhang, Chao Yang +1
Based on the Just-Noticeable-Difference (JND) criterion, a subjective video quality assessment (VQA) dataset, called the VideoSet, was constructed recently. In this work, we propos…
Analysis and prediction of JND-based video quality model
Haiqiang Wang, Xinfeng Zhang, Chao Yang +1
The just-noticeable-difference (JND) visual perception property has received much attention in characterizing human subjective viewing experience of compressed video. In this work,…
Prediction of Satisfied User Ratio for Compressed Video
Haiqiang Wang, Ioannis Katsavounidis, Qin Huang +2
A large-scale video quality dataset called the VideoSet has been constructed recently to measure human subjective experience of H.264 coded video in terms of the just-noticeable-di…
VideoSet: A Large-Scale Compressed Video Quality Dataset Based on JND Measurement
Haiqiang Wang, Ioannis Katsavounidis, Jiantong Zhou +11
A new methodology to measure coded image/video quality using the just-noticeable-difference (JND) idea was proposed. Several small JND-based image/video quality datasets were relea…
A GMM-Based Stair Quality Model for Human Perceived JPEG Images
Sudeng Hu, Haiqiang Wang, C. -C. Jay Kuo
Based on the notion of just noticeable differences (JND), a stair quality function (SQF) was recently proposed to model human perception on JPEG images. Furthermore, a k-means clus…
Recovering Missing Coefficients in DCT-Transformed Images
Shujun Li, Andreas Karrenbauer, Dietmar Saupe +1
A general method for recovering missing DCT coefficients in DCT-transformed images is presented in this work. We model the DCT coefficients recovery problem as an optimization prob…
An Improved DC Recovery Method from AC Coefficients of DCT-Transformed Images
Shujun Li, Junaid Jameel Ahmad, Dietmar Saupe +1
Motivated by the work of Uehara et al. [1], an improved method to recover DC coefficients from AC coefficients of DCT-transformed images is investigated in this work, which finds a…
