Perceptual Quality Assessment of Colored 3D Point Clouds
Honglei Su, Qi Liu, Zhengfang Duanmu +2
The real-world applications of 3D point clouds have been growing rapidly in recent years, but not much effective work has been dedicated to perceptual quality assessment of colored…
Quantifying Visual Image Quality: A Bayesian View
Zhengfang Duanmu, Wentao Liu, Zhongling Wang +1
Image quality assessment (IQA) models aim to establish a quantitative relationship between visual images and their perceptual quality by human observers. IQA modeling plays a speci…
Assessing the Quality-of-Experience of Adaptive Bitrate Video Streaming
Zhengfang Duanmu, Wentao Liu, Zhuoran Li +4
The diversity of video delivery pipeline poses a grand challenge to the evaluation of adaptive bitrate (ABR) streaming algorithms and objective quality-of-experience (QoE) models.…
Characterizing Generalized Rate-Distortion Performance of Video Coding: An Eigen Analysis Approach
Zhengfang Duanmu, Wentao Liu, Zhuoran Li +2
Rate-distortion (RD) theory is at the heart of lossy data compression. Here we aim to model the generalized RD (GRD) trade-off between the visual quality of a compressed video and…
A Knowledge-Driven Quality-of-Experience Model for Adaptive Streaming Videos
Zhengfang Duanmu, Wentao Liu, Diqi Chen +4
The fundamental conflict between the enormous space of adaptive streaming videos and the limited capacity for subjective experiment casts significant challenges to objective Qualit…
Modeling Generalized Rate-Distortion Functions
Zhengfang Duanmu, Wentao Liu, Zhou Wang
Many multimedia applications require precise understanding of the rate-distortion characteristics measured by the function relating visual quality to media attributes, for which we…
dipIQ: Blind Image Quality Assessment by Learning-to-Rank Discriminable Image Pairs
Kede Ma, Wentao Liu, Tongliang Liu +2
Objective assessment of image quality is fundamentally important in many image processing tasks. In this work, we focus on learning blind image quality assessment (BIQA) models whi…
