Awesome Object Shadow Generation 
A curated list of resources including papers, datasets, and relevant links pertaining to object shadow generation. Shadow generation aims to generate plausible shadow for the inserted foreground object in a composite image. For more complete resources on general image composition, please refer to Awesome-Image-Composition.
