# YOLOLite-edge_s (ONNX, 640x640)

YOLOLite-edge_s is a lightweight, CPU-oriented object detection model designed for real-time performance on edge devices and industrial systems.  
The model is part of the YOLOLite family, focusing on **practical latency**, **small model size**, and **stable performance across many real-world datasets**.

📊 Benchmark Results can be found under BENCHMARK.md in the repo

## 🔍 Key Features

- **Real-time CPU performance** (25–30 FPS end-to-end on desktop CPU)
- **Fast ONNX inference** (14–18 ms per frame)
- Optimized for **industrial and edge applications**
- Supports **resize** or **letterbox** preprocessing
- Reliable performance across 40+ diverse Roboflow100 datasets

## ⚡ Real-World Performance (CPU, ONNX Runtime)

Tested using 1080p traffic footage (`intersection.mp4`) and the script  
`onnx_intersection_showcase.py`.

| Measurement | Result |
|------------|--------|
| **End-to-end FPS** | **25–30 FPS** |
| **Raw ONNX inference** | **14–18 ms** (~55–70 FPS) |
| **Resolution** | 640 × 640 |
| **Execution Provider** | CPUExecutionProvider |

These values include the **full pipeline**: video → resize → inference → NMS → drawing.

## 🧪 Example Usage

```python
from infer_onnx import ONNX_Predict
import cv2

predict = ONNX_Predict("edge_s_640_resize.onnx",
                       providers=["CPUExecutionProvider"],
                       use_letterbox=False)

frame = cv2.imread("image.jpg")
boxes, scores, classes = predict.infer_image(frame, img_size=640)

for (x1, y1, x2, y2), score, cls in zip(boxes, scores, classes):
    print(x1, y1, x2, y2, score, cls)
