HDRSDR-VQA: A Subjective Video Quality Dataset for HDR and SDR Comparative Evaluation
Bowen Chen, Cheng-han Lee, Yixu Chen +3
We introduce HDRSDR-VQA, a large-scale video quality assessment dataset designed to facilitate comparative analysis between High Dynamic Range (HDR) and Standard Dynamic Range (SDR…
Satellite Streaming Video QoE Prediction: A Real-World Subjective Database and Network-Level Prediction Models
Bowen Chen, Zaixi Shang, Jae Won Chung +5
Demand for streaming services, including satellite, continues to exhibit unprecedented growth. Internet Service Providers find themselves at the crossroads of technological advance…
Encoder-Quantization-Motion-based Video Quality Metrics
Yixu Chen, Zaixi Shang, Hai Wei +2
In an adaptive bitrate streaming application, the efficiency of video compression and the encoded video quality depend on both the video codec and the quality metric used to perfor…
HDR or SDR? A Subjective and Objective Study of Scaled and Compressed Videos
Joshua P. Ebenezer, Zaixi Shang, Yixu Chen +4
We conducted a large-scale study of human perceptual quality judgments of High Dynamic Range (HDR) and Standard Dynamic Range (SDR) videos subjected to scaling and compression leve…
HDR-ChipQA: No-Reference Quality Assessment on High Dynamic Range Videos
Joshua P. Ebenezer, Zaixi Shang, Yongjun Wu +3
We present a no-reference video quality model and algorithm that delivers standout performance for High Dynamic Range (HDR) videos, which we call HDR-ChipQA. HDR videos represent w…
Making Video Quality Assessment Models Robust to Bit Depth
Joshua P. Ebenezer, Zaixi Shang, Yongjun Wu +3
We introduce a novel feature set, which we call HDRMAX features, that when included into Video Quality Assessment (VQA) algorithms designed for Standard Dynamic Range (SDR) videos,…
Subjective Assessment of High Dynamic Range Videos Under Different Ambient Conditions
Zaixi Shang, Joshua P. Ebenezer, Alan C. Bovik +3
High Dynamic Range (HDR) videos can represent a much greater range of brightness and color than Standard Dynamic Range (SDR) videos and are rapidly becoming an industry standard. H…
ChipQA: No-Reference Video Quality Prediction via Space-Time Chips
Joshua P. Ebenezer, Zaixi Shang, Yongjun Wu +3
We propose a new model for no-reference video quality assessment (VQA). Our approach uses a new idea of highly-localized space-time (ST) slices called Space-Time Chips (ST Chips).…
Assessment of Subjective and Objective Quality of Live Streaming Sports Videos
Zaixi Shang, Joshua P. Ebenezer, Alan C. Bovik +3
Video live streaming is gaining prevalence among video streaming services, especially for the delivery of popular sporting events. Many objective Video Quality Assessment (VQA) mod…
No-Reference Video Quality Assessment Using Space-Time Chips
Joshua P. Ebenezer, Zaixi Shang, Yongjun Wu +2
We propose a new prototype model for no-reference video quality assessment (VQA) based on the natural statistics of space-time chips of videos. Space-time chips (ST-chips) are a ne…
