MD-VQA: Multi-Dimensional Quality Assessment for UGC Live Videos
Zicheng Zhang, Wei Wu, Wei Sun +5
User-generated content (UGC) live videos are often bothered by various distortions during capture procedures and thus exhibit diverse visual qualities. Such source videos are furth…
Subjective and Objective Quality Assessment for in-the-Wild Computer Graphics Images
Zicheng Zhang, Wei Sun, Yingjie Zhou +5
Computer graphics images (CGIs) are artificially generated by means of computer programs and are widely perceived under various scenarios, such as games, streaming media, etc. In p…
EEP-3DQA: Efficient and Effective Projection-based 3D Model Quality Assessment
Zicheng Zhang, Wei Sun, Yingjie Zhou +4
Currently, great numbers of efforts have been put into improving the effectiveness of 3D model quality assessment (3DQA) methods. However, little attention has been paid to the com…
DDH-QA: A Dynamic Digital Humans Quality Assessment Database
Zicheng Zhang, Yingjie Zhou, Wei Sun +4
In recent years, large amounts of effort have been put into pushing forward the real-world application of dynamic digital human (DDH). However, most current quality assessment rese…
Deep Neural Network for Blind Visual Quality Assessment of 4K Content
Wei Lu, Wei Sun, Xiongkuo Min +7
The 4K content can deliver a more immersive visual experience to consumers due to the huge improvement of spatial resolution. However, existing blind image quality assessment (BIQA…
Blind Surveillance Image Quality Assessment via Deep Neural Network Combined with the Visual Saliency
Wei Lu, Wei Sun, Wenhan Zhu +4
The intelligent video surveillance system (IVSS) can automatically analyze the content of the surveillance image (SI) and reduce the burden of the manual labour. However, the SIs m…
A No-Reference Deep Learning Quality Assessment Method for Super-resolution Images Based on Frequency Maps
Zicheng Zhang, Wei Sun, Xiongkuo Min +4
To support the application scenarios where high-resolution (HR) images are urgently needed, various single image super-resolution (SISR) algorithms are developed. However, SISR is…
A Deep Learning based No-reference Quality Assessment Model for UGC Videos
Wei Sun, Xiongkuo Min, Wei Lu +1
Quality assessment for User Generated Content (UGC) videos plays an important role in ensuring the viewing experience of end-users. Previous UGC video quality assessment (VQA) stud…
DAMO-NLP at SemEval-2022 Task 11: A Knowledge-based System for Multilingual Named Entity Recognition
Xinyu Wang, Yongliang Shen, Jiong Cai +9
The MultiCoNER shared task aims at detecting semantically ambiguous and complex named entities in short and low-context settings for multiple languages. The lack of contexts makes…
No-Reference Quality Assessment for 3D Colored Point Cloud and Mesh Models
Zicheng Zhang, Wei Sun, Xiongkuo Min +3
To improve the viewer's Quality of Experience (QoE) and optimize computer graphics applications, 3D model quality assessment (3D-QA) has become an important task in the multimedia…
