SDRTV-to-HDRTV Conversion via Spatial-Temporal Feature Fusion

no code implementations4 Nov 2022 Kepeng Xu, Li Xu, Gang He, Chang Wu, Zijia Ma, Ming Sun, Yu-Wing Tai

To evaluate the performance of the proposed method, we construct a corresponding multi-frame dataset using HDR video of the HDR10 standard to conduct a comprehensive evaluation of different methods.

Towards Robust SDRTV-to-HDRTV via Dual Inverse Degradation Network

no code implementations7 Jul 2023 Kepeng Xu, Li Xu, Gang He, Wenxin Yu, Yunsong Li

In this study, we address the emerging necessity of converting Standard Dynamic Range Television (SDRTV) content into High Dynamic Range Television (HDRTV) in light of the limited number of native HDRTV content.
