 [2022/7] Code for [DINO](https://arxiv.org/pdf/2203.03605.pdf) is available [here](https://github.com/IDEACVR/DINO)!
 
 [2022/6]: We release a unified detection and segmentation model [Mask DINO](https://arxiv.org/pdf/2206.02777.pdf) that achieves the best results on all the three segmentation tasks (**54.5** AP on [COCO instance leaderboard](https://paperswithcode.com/sota/instance-segmentation-on-coco-minival), **59.4** PQ on [COCO panoptic leaderboard](https://paperswithcode.com/sota/panoptic-segmentation-on-coco-minival), and **60.8** mIoU on [ADE20K semantic leaderboard](https://paperswithcode.com/sota/semantic-segmentation-on-ade20k))! Code will be available [here](https://github.com/IDEACVR/MaskDINO).
