DINO: DETR with Improved DeNoising Anchor Boxes for End-to-End Object Detection

🤖 Plain-English Summary

We present DINO (\textbf{D}ETR with \textbf{I}mproved de\textbf{N}oising anch\textbf{O}r boxes), a advanced end-to-end object detector. Compared to other models on the leaderboard, DINO significantly reduces its model size and pre-training data size while achieving better results.

🔑 Key Findings

• DINO improves over previous DETR-like models in performance and efficiency by using a contrastive way for denoising training, a mixed query selection method for anchor initialization, and a look forward twice scheme for box prediction.
• DINO achieves $49.4$AP in $12$ epochs and $51.3$AP in $24$ epochs on COCO with a ResNet-50 backbone and multi-scale features, yielding a significant improvement of $\textbf{+6.0}$\textbf{AP} and $\textbf{+2.7}$\textbf{AP}, respectively, compared to DN-DETR, the previous best DETR-like model.
• DINO scales well in both model size and data size.
