​​ObjectAug: Object-level Data Augmentation for Semantic Image Segmentation

The authors suggest ObjectAug perform object-level augmentation for semantic image segmentation.
This approach has the following steps:
- decouple the image into individual objects and the background using the semantic labels;
- augment each object separately;
- restore the black area brought by object augmentation using image inpainting;
- assemble the augmented objects and background;

Thanks to the fact that objects are separate, we can apply different augmentations to different categories and combine them with image-level augmentation methods.
