Rotating black holes in 4D Einstein-Gauss-Bonnet gravity and its shadow
Journal of Cosmology and Astroparticle Physics, 2020 Recently there has been a surge of interest in regularizing, a D → 4 limit of, the Einstein-Gauss-Bonnet (EGB) gravity, and the resulting regularized 4D EGB gravity has nontrivial dynamics. The theory admits spherically symmetric black holes generalizing

From Shadow Segmentation to Shadow Removal [PDF]
European Conference on Computer Vision, 2020 The requirement for paired shadow and shadow-free images limits the size and diversity of shadow removal datasets and hinders the possibility of training large-scale, robust shadow removal algorithms.

Shadow Removal via Shadow Image Decomposition [PDF]
IEEE International Conference on Computer Vision, 2019 We propose a novel deep learning method for shadow removal. Inspired by physical models of shadow formation, we use a linear illumination transformation to model the shadow effects in the image that allows the shadow image to be expressed as a ...

Shedding Light on the Shadow Economy: A Global Database and the Interaction with the Official One
Social Science Research Network, 2019 Using the multiple indicator-multiple cause (MIMIC) approach, this paper generates a novel global database by estimating the size of the shadow economy for 157 countries over 1991 to 2017. The results suggest that the OECD countries are by far the lowest

The Financing of Local Government in China: Stimulus Loan Wanes and Shadow Banking Waxes
Journal of Financial Economics, 2017 The upsurge of shadow banking is typically driven by rising financing demand from certain real sectors. In China, the 4 trillion yuan stimulus package in 2009 was behind the rapid growth of shadow banking after 2012, expediting the development of Chinese

Comparative research on shadow education: Achievements, challenges, and the agenda ahead
, 2020 This paper reviews research on private supplementary tutoring, widely known as shadow education, during the initial decades of the present century It takes as its starting point the first global study of the phenomenon, published in 1999, though notes ...

Stacked Conditional Generative Adversarial Networks for Jointly Learning Shadow Detection and Shadow Removal [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 Understanding shadows from a single image consists of two types of task in previous studies, containing shadow detection and shadow removal. In this paper, we present a multi-task perspective, which is not embraced by any existing work, to jointly learn ...
