TL;DR: The novel VIDIT dataset used in the AIM 2020 challenge and the different proposed solutions and final evaluation results over the 3 challenge tracks are presented.
Book ChapterDOI
SA-AE for Any-to-Any Relighting
TL;DR: Li et al. as mentioned in this paper proposed a self-attention auto-encoder for any-to-any relighting, which adopted an implicit scene representation learned by the encoder to render the relit image using the decoder based on the learned scene representation.
Journal ArticleDOI
PNRNet: Physically-Inspired Neural Rendering for Any-to-Any Relighting
TL;DR: PNRNet is presented, a novel neural architecture that decomposes the any-to-any relighting task into three simpler sub-tasks, i.e. lighting estimation, color temperature transfer, and lighting direction transfer, to avoid the task-aliasing effects.
