**TLDR:** An approach in transformer-based detection that makes attention computation more selective, improving convergence speed and small-object performance.

<p>Deformable DETR was developed in response to the slow convergence and small-object challenges of pure transformer detection architectures. By focusing attention not on the whole image but on relevant multi-scale points, it improves efficiency. This played an important role in making transformer-based visual detection systems more practical for real deployment.</p>
