**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)
|
