ResNet-based Face Classification Model 🎭

This model is trained to distinguish between real human faces and AI-generated faces using a ResNet-based architecture.

Model Description 📝

Model Architecture

• Deep CNN with residual connections based on ResNet architecture
• Input shape: (224, 224, 3)
• Multiple residual blocks with increasing filter sizes [64, 128, 256, 512]
• Global average pooling
• Dense layers with dropout for classification
• Binary output with sigmoid activation

Task

Binary classification to determine if a face image is real (human) or AI-generated.

Usage 💻

from tensorflow.keras.models import load_model
import cv2
import numpy as np

# Load the model
model = load_model('face_classification_model1')

# Preprocess image
def preprocess_image(image_path):
    img = cv2.imread(image_path)
    img = cv2.resize(img, (224, 224))
    img = img / 255.0
    return np.expand_dims(img, axis=0)

# Make prediction
image = preprocess_image('face_image.jpg')
prediction = model.predict(image)
is_real = prediction[0][0] > 0.5

Ethical Considerations 🤝

This model is designed for research and educational purposes only. Users should:

• Obtain proper consent when processing personal face images
• Be aware of potential biases in face detection systems
• Consider privacy implications when using face analysis tools
• Not use this model for surveillance or harmful applications

Technical Limitations ⚠️

1. Current performance limitations:

   • Accuracy only slightly above random chance
   • May require ensemble methods for better results
   • Limited testing on diverse datasets

2. Recommended improvements:

   • Extended training with larger datasets
   • Implementation of data augmentation
   • Hyperparameter optimization
   • Transfer learning from pre-trained models
