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 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…
