Dynamic resolution switching for live streaming
Xin Xiong, Yixu Chen, Hai Wei +2
Conventional adaptive bitrate (ABR) streaming systems typically rely on static bitrate ladders to optimize Quality of Experience (QoE). While operationally simple, this "one-size-f…
Transforming Video Subjective Testing with Training, Engagement, and Real-Time Feedback
Kumar Rahul, Sriram Sethuraman, Andrew Segall +1
Subjective video quality assessment is crucial for optimizing streaming and compression, yet traditional protocols face limitations in capturing nuanced perceptual differences and…
ICME 2025 Generalizable HDR and SDR Video Quality Measurement Grand Challenge
Yixu Chen, Bowen Chen, Hai Wei +16
This paper reports IEEE International Conference on Multimedia \& Expo (ICME) 2025 Grand Challenge on Generalizable HDR and SDR Video Quality Measurement. With the rapid developmen…
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…
Video Quality Assessment for Resolution Cross-Over in Live Sports
Jingwen Zhu, Yixu Chen, Hai Wei +2
In adaptive bitrate streaming, resolution cross-over refers to the point on the convex hull where the encoding resolution should switch to achieve better quality. Accurate cross-ov…
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…
Subjective and Objective Quality Assessment of High-Motion Sports Videos at Low-Bitrates
Joshua P. Ebenezer, Yixu Chen, Yongjun Wu +2
Videos often have to be transmitted and stored at low bitrates due to poor network connectivity during adaptive bitrate streaming. Designing optimal bitrate ladders that would sele…
