Deep View Synthesis via Self-Consistent Generative Network

1 code implementation19 Jan 2021 Zhuoman Liu, Wei Jia, Ming Yang, Peiyao Luo, Yong Guo, Mingkui Tan

To address the above issues, in this paper, we propose a novel deep generative model, called Self-Consistent Generative Network (SCGN), which synthesizes novel views from the given input views without explicitly exploiting the geometric information.

Rethinking deinterlacing for early interlaced videos

no code implementations27 Nov 2020 Yang Zhao, Wei Jia, Ronggang Wang

Traditional deinterlacing approaches are mainly focused on early interlacing scanning systems and thus cannot handle the complex and complicated artifacts in real-world early interlaced videos.
