A FUNQUE Approach to the Quality Assessment of Compressed HDR Videos
Abhinau K. Venkataramanan, Cosmin Stejerean, Ioannis Katsavounidis +1
Recent years have seen steady growth in the popularity and availability of High Dynamic Range (HDR) content, particularly videos, streamed over the internet. As a result, assessing…
Bitrate Ladder Construction using Visual Information Fidelity
Krishna Srikar Durbha, Hassene Tmar, Cosmin Stejerean +2
Recently proposed perceptually optimized per-title video encoding methods provide better BD-rate savings than fixed bitrate-ladder approaches that have been employed in the past. H…
Encoder Complexity Control in SVT-AV1 by Speed-Adaptive Preset Switching
Lena Eichermüller, Gaurang Chaudhari, Ioannis Katsavounidis +4
Current developments in video encoding technology lead to continuously improving compression performance but at the expense of increasingly higher computational demands. Regarding…
Study of Subjective and Objective Quality Assessment of Mobile Cloud Gaming Videos
Avinab Saha, Yu-Chih Chen, Chase Davis +5
We present the outcomes of a recent large-scale subjective study of Mobile Cloud Gaming Video Quality Assessment (MCG-VQA) on a diverse set of gaming videos. Rapid advancements in…
GAMIVAL: Video Quality Prediction on Mobile Cloud Gaming Content
Yu-Chih Chen, Avinab Saha, Chase Davis +5
The mobile cloud gaming industry has been rapidly growing over the last decade. When streaming gaming videos are transmitted to customers' client devices from cloud servers, algori…
One Transform To Compute Them All: Efficient Fusion-Based Full-Reference Video Quality Assessment
Abhinau K. Venkataramanan, Cosmin Stejerean, Ioannis Katsavounidis +1
The Visual Multimethod Assessment Fusion (VMAF) algorithm has recently emerged as a state-of-the-art approach to video quality prediction, that now pervades the streaming and socia…
Lightweight Image Codec via Multi-Grid Multi-Block-Size Vector Quantization (MGBVQ)
Yifan Wang, Zhanxuan Mei, Ioannis Katsavounidis +1
A multi-grid multi-block-size vector quantization (MGBVQ) method is proposed for image coding in this work. The fundamental idea of image coding is to remove correlations among pix…
A Machine Learning Approach to Optimal Inverse Discrete Cosine Transform (IDCT) Design
Yifan Wang, Zhanxuan Mei, Chia-Yang Tsai +2
The design of the optimal inverse discrete cosine transform (IDCT) to compensate the quantization error is proposed for effective lossy image compression in this work. The forward…
A Hitchhiker's Guide to Structural Similarity
Abhinau K. Venkataramanan, Chengyang Wu, Alan C. Bovik +2
The Structural Similarity (SSIM) Index is a very widely used image/video quality model that continues to play an important role in the perceptual evaluation of compression algorith…
A Simple Model for Subject Behavior in Subjective Experiments
Zhi Li, Christos G. Bampis, Lukáš Krasula +2
In a subjective experiment to evaluate the perceptual audiovisual quality of multimedia and television services, raw opinion scores collected from test subjects are often noisy and…
Towards Perceptually Optimized End-to-end Adaptive Video Streaming
Christos G. Bampis, Zhi Li, Ioannis Katsavounidis +3
Measuring Quality of Experience (QoE) and integrating these measurements into video streaming algorithms is a multi-faceted problem that fundamentally requires the design of compre…
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…
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…
