# ADE20K

Introduced by Zhou et al. in [Scene Parsing Through ADE20K Dataset](https://paperswithcode.com/paper/scene-parsing-through-ade20k-dataset).

The ADE20K semantic segmentation dataset contains more than 20K scene-centric images exhaustively annotated with pixel-level objects and object parts labels. There are totally 150 semantic categories, which include stuffs like sky, road, grass, and discrete objects like person, car, bed.

- Training speed is measured with A100 GPU.
- Please set `with_cp=True` to save memory if you meet `out-of-memory` issues.
- The logs are our recent newly trained ones. There are slight differences between the results in logs and our paper.
