# Meituan YOLOv6 |
|
|
|
## Overview |
|
|
|
[Meituan](https://about.meituan.com/) YOLOv6 is a cutting-edge object detector that offers remarkable balance between speed and accuracy, making it a popular choice for real-time applications. This model introduces several notable enhancements on its architecture and training scheme, including the implementation of a Bi-directional Concatenation (BiC) module, an anchor-aided training (AAT) strategy, and an improved backbone and neck design for state-of-the-art accuracy on the COCO dataset. |

|
### Key Features |
|
|
|
- **Bi-directional Concatenation (BiC) Module:** YOLOv6 introduces a BiC module in the neck of the detector, enhancing localization signals and delivering performance gains with negligible speed degradation. |
|
- **Anchor-Aided Training (AAT) Strategy:** This model proposes AAT to enjoy the benefits of both anchor-based and anchor-free paradigms without compromising inference efficiency. |
|
- **Enhanced Backbone and Neck Design:** By deepening YOLOv6 to include another stage in the backbone and neck, this model achieves state-of-the-art performance on the COCO dataset at high-resolution input. |
|
- **Self-Distillation Strategy:** A new self-distillation strategy is implemented to boost the performance of smaller models of YOLOv6, enhancing the auxiliary regression branch during training and removing it at inference to avoid a marked speed decline. |
|
|
|
## Pre-trained Models |
|
|
|
YOLOv6 provides various pre-trained models with different scales: |
|
|
|
- YOLOv6-N: 37.5% AP on COCO val2017 at 1187 FPS with NVIDIA Tesla T4 GPU. |
|
- YOLOv6-S: 45.0% AP at 484 FPS. |
|
- YOLOv6-M: 50.0% AP at 226 FPS. |
|
- YOLOv6-L: 52.8% AP at 116 FPS. |
|
- YOLOv6-L6: State-of-the-art accuracy in real-time. |
|
|
|
YOLOv6 also provides quantized models for different precisions and models optimized for mobile platforms. |
|
|
|
## Usage |
|
|
|
### Python API |
|
|
|
```python |
|
from ultralytics import YOLO |
|
|
|
model = YOLO("yolov6n.yaml") # build new model from scratch |
|
model.info() # display model information |
|
model.predict("path/to/image.jpg") # predict |
|
``` |
