Full-reference Video Quality Assessment for User Generated Content Transcoding

no code implementations19 Dec 2023 Zihao Qi, Chen Feng, Duolikun Danier, Fan Zhang, Xiaozhong Xu, Shan Liu, David Bull

In this work, we observe that existing full-/no-reference quality metrics fail to accurately predict the perceptual quality difference between transcoded UGC content and the corresponding unpristine references.

Enhancing HDR Video Compression through CNN-based Effective Bit Depth Adaptation

1 code implementation18 Jul 2022 Chen Feng, Zihao Qi, Duolikun Danier, Fan Zhang, Xiaozhong Xu, Shan Liu, David Bull

In this work, we modify the MFRNet network architecture to enable multiple frame processing, and the new network, multi-frame MFRNet, has been integrated into the EBDA framework using two Versatile Video Coding (VVC) host codecs: VTM 16. 2 and the Fraunhofer Versatile Video Encoder (VVenC 1. 4. 0).
