Deformable DETR

Deformable DETR: Deformable Transformers for End-to-End Object Detection

Abstract

DETR has been recently proposed to eliminate the need for many hand-designed components in object detection while demonstrating good performance. However, it suffers from slow convergence and limited feature spatial resolution, due to the limitation of Transformer attention modules in processing image feature maps. To mitigate these issues, we proposed Deformable DETR, whose attention modules only attend to a small set of key sampling points around a reference. Deformable DETR can achieve better performance than DETR (especially on small objects) with 10 times less training epochs. Extensive experiments on the COCO benchmark demonstrate the effectiveness of our approach.

Results and Models

Backbone Model Lr schd box AP Config Download
R-50 Deformable DETR 50e 44.3 config model | log
R-50 + iterative bounding box refinement 50e 46.2 config model | log
R-50 ++ two-stage Deformable DETR 50e 47.0 config model | log

NOTE

  1. All models are trained with batch size 32.
  2. The performance is unstable. Deformable DETR and iterative bounding box refinement may fluctuate about 0.3 mAP. two-stage Deformable DETR may fluctuate about 0.2 mAP.
