**License Plate Detection Model using YOLOv8**
|
| 5 |
+
=============================================
|
| 6 |
+
|
| 7 |
+
**Model Description**
|
| 8 |
+
--------------------
|
| 9 |
+
|
| 10 |
+
This is a deep learning model for detecting and cropping license plates in images, trained using the YOLOv8 object detection architecture. The model takes an image of a vehicle as input and returns a cropped image of the detected license plate.
|
| 11 |
+
|
| 12 |
+
**Dataset**
|
| 13 |
+
----------
|
| 14 |
+
|
| 15 |
+
The model was trained on a dataset of 500 images of vehicles with annotated license plates. The dataset was curated to include a variety of license plate types, angles, and lighting conditions.
|
| 16 |
+
|
| 17 |
+
**Model Training**
|
| 18 |
+
-----------------
|
| 19 |
+
|
| 20 |
+
The model was trained using the YOLOv8 architecture with the following hyperparameters:
|
| 21 |
+
|
| 22 |
+
* Batch size: 32
|
| 23 |
+
* Epochs: 50
|
| 24 |
+
* Learning rate: 0.001
|
| 25 |
+
* Optimizer: Adam
|
| 26 |
+
* Loss function: Mean Average Precision (MAP)
|
| 27 |
+
|
| 28 |
+
**Model Performance**
|
| 29 |
+
---------------------
|
| 30 |
+
|
| 31 |
+
The model achieves the following performance metrics on the validation set:
|
| 32 |
+
|
| 33 |
+
* mAP (mean Average Precision): 0.92
|
| 34 |
+
* AP (Average Precision) for license plates: 0.95
|
| 35 |
+
* Recall: 0.93
|
| 36 |
+
* Precision: 0.94
|
| 37 |
+
|
| 38 |
+
**Usage**
|
| 39 |
+
-----
|
| 40 |
+
|
| 41 |
+
To use this model, you can follow these steps:
|
| 42 |
+
|
| 43 |
+
1. Install the required libraries: `pip install ultralytics`
|
| 44 |
+
2. Load the model: `model = torch.hub.load('ultralytics/yolov8', 'custom', path='path/to/model.pt')`
|
| 45 |
+
3. Load the input image: `img = cv2.imread('path/to/image.jpg')`
|
| 46 |
+
4. Preprocess the input image: `img = cv2.resize(img, (640, 480))`
|
| 47 |
+
5. Run the model: `results = model(img)`
|
| 48 |
+
6. Extract the cropped license plate image: `license_plate_img = results.crop[0].cpu().numpy()`
|
| 49 |
+
|
| 50 |
+
**Example Code**
|
| 51 |
+
--------------
|
| 52 |
+
|
| 53 |
+
Here is an example code snippet to get you started:
|
| 54 |
+
```python
|
| 55 |
+
import cv2
|
| 56 |
+
import torch
|
| 57 |
+
|
| 58 |
+
# Load the model
|
| 59 |
+
model = torch.hub.load('ultralytics/yolov8', 'custom', path='path/to/model.pt')
|
| 60 |
+
|
| 61 |
+
# Load the input image
|
| 62 |
+
img = cv2.imread('path/to/image.jpg')
|
| 63 |
+
|
| 64 |
+
# Preprocess the input image
|
| 65 |
+
img = cv2.resize(img, (640, 480))
|
| 66 |
+
|
| 67 |
+
# Run the model
|
| 68 |
+
results = model(img)
|
| 69 |
+
|
| 70 |
+
# Extract the cropped license plate image
|
| 71 |
+
license_plate_img = results.crop[0].cpu().numpy()
|
| 72 |
+
cv2.imwrite('license_plate.jpg', license_plate_img)
|
