# RT-DETR |
|
|
|
## Overview |
|
|
|
Real-Time Detection Transformer (RT-DETR) is an end-to-end object detector that provides real-time performance while maintaining high accuracy. It efficiently processes multi-scale features by decoupling intra-scale interaction and cross-scale fusion, and supports flexible adjustment of inference speed using different decoder layers without retraining. RT-DETR outperforms many real-time object detectors on accelerated backends like CUDA with TensorRT. |
|
|
|
### Key Features |
|
|
|
- **Efficient Hybrid Encoder:** RT-DETR uses an efficient hybrid encoder that processes multi-scale features by decoupling intra-scale interaction and cross-scale fusion. This design reduces computational costs and allows for real-time object detection. |
|
- **IoU-aware Query Selection:** RT-DETR improves object query initialization by utilizing IoU-aware query selection. This allows the model to focus on the most relevant objects in the scene. |
|
- **Adaptable Inference Speed:** RT-DETR supports flexible adjustments of inference speed by using different decoder layers without the need for retraining. This adaptability facilitates practical application in various real-time object detection scenarios. |
|
|
|
## Pre-trained Models |
|
|
|
Ultralytics RT-DETR provides several pre-trained models with different scales: |
|
|
|
- RT-DETR-L: 53.0% AP on COCO val2017, 114 FPS on T4 GPU |
|
- RT-DETR-X: 54.8% AP on COCO val2017, 74 FPS on T4 GPU |
|
|
|
## Usage |
|
|
|
### Python API |
|
|
|
```python |
|
from ultralytics import RTDETR |
|
|
|
model = RTDETR("rtdetr-l.pt") |
|
model.info() # display model information |
|
model.predict("path/to/image.jpg") # predict |
|
``` |
|
|
