Gravitational Test beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole [PDF]
Physical Review Letters, 2020 The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new and clean gravitational test of the black-hole metric in the strong-field

ShadowFormer: Global Context Helps Image Shadow Removal [PDF]
AAAI Conference on Artificial Intelligence, 2023 Recent deep learning methods have achieved promising results in image shadow removal. However, most of the existing approaches focus on working locally within shadow and non-shadow regions, resulting in severe artifacts around the shadow boundaries as ...

DC-ShadowNet: Single-Image Hard and Soft Shadow Removal Using Unsupervised Domain-Classifier Guided Network [PDF]
IEEE International Conference on Computer Vision, 2021 Shadow removal from a single image is generally still an open problem. Most existing learning-based methods use supervised learning and require a large number of paired images (shadow and corresponding non-shadow images) for training.
