+
## Usage 💻
|
| 84 |
+
|
| 85 |
+
```python
|
| 86 |
+
from tensorflow.keras.models import load_model
|
| 87 |
+
import cv2
|
| 88 |
+
import numpy as np
|
| 89 |
+
|
| 90 |
+
# Load the model
|
| 91 |
+
model = load_model('face_classification_model1')
|
| 92 |
+
|
| 93 |
+
# Preprocess image
|
| 94 |
+
def preprocess_image(image_path):
|
| 95 |
+
img = cv2.imread(image_path)
|
| 96 |
+
img = cv2.resize(img, (224, 224))
|
| 97 |
+
img = img / 255.0
|
| 98 |
+
return np.expand_dims(img, axis=0)
|
| 99 |
+
|
| 100 |
+
# Make prediction
|
| 101 |
+
image = preprocess_image('face_image.jpg')
|
| 102 |
+
prediction = model.predict(image)
|
| 103 |
+
is_real = prediction[0][0] > 0.5
|
| 104 |
+
```
|
| 105 |
+

|
| 107 |
+
## Ethical Considerations 🤝
|
| 108 |
+
|
| 109 |
+
This model is designed for research and educational purposes only. Users should:
|
| 110 |
+
- Obtain proper consent when processing personal face images
|
| 111 |
+
- Be aware of potential biases in face detection systems
|
| 112 |
+
- Consider privacy implications when using face analysis tools
|
| 113 |
+
- Not use this model for surveillance or harmful applications
|
| 114 |
+
|
| 115 |
+
## Technical Limitations ⚠️
|
| 116 |
+
|
| 117 |
+
1. Current performance limitations:
|
| 118 |
+
- Accuracy only slightly above random chance
|
| 119 |
+
- May require ensemble methods for better results
|
| 120 |
+
- Limited testing on diverse datasets
|
| 121 |
+
|
| 122 |
+
2. Recommended improvements:
|
| 123 |
+
- Extended training with larger datasets
|
| 124 |
+
- Implementation of data augmentation
|
| 125 |
+
- Hyperparameter optimization
|
| 126 |
+
- Transfer learning from pre-trained models
