Transformer Based Detector Implementation Detr Deformable Detr Dino Variants

via “transformer-based detection with deformable attention and query optimization”

OpenMMLab detection toolbox with 300+ models.

Unique: Implements DINO (DETR with Improved deNoising) which adds contrastive learning between positive/negative queries and mixed query selection strategy, achieving state-of-the-art accuracy without hand-crafted components; deformable attention reduces complexity from O(n²) to O(n) by learning spatial offsets to relevant regions

vs others: More elegant than anchor-based detectors because it eliminates hand-crafted anchors and NMS; more efficient than vanilla DETR because deformable attention focuses on relevant regions; better convergence than early DETR variants due to contrastive learning and query optimization
