What is RT-DETR and what is its idea?

RT-DETR (Real-Time DETR) is a modification of the DETR (Detection Transformer) model designed to accelerate object detection in real-time.

The idea of RT-DETR is to simplify the DETR architecture and optimize the training and inference process to achieve high speed without significant loss of accuracy. Unlike the original DETR, which uses a complex transformer and requires lengthy training times, RT-DETR employs lighter components and improved optimization methods.

Basically, RT-DETR retains the end-to-end detection concept using transformers but adapts it for speed, which is important for resource-constrained applications or those requiring low latency.
