🧠 Face Recognition System (ArcFace + YOLOv8)
📖 Overview
This repository hosts a production-ready Face Recognition Pipeline designed for high-accuracy biometric identification. Unlike standard recognizers, this system integrates YOLOv8 for robust face detection and alignment before feature extraction.
The core recognition model is built upon a Wide ResNet-101-2 backbone, trained with a hybrid loss function (ArcFace + Center Loss) to generate highly discriminative 512-dimensional embeddings.
🌟 Key Features
- Robust Detection: Uses YOLOv8 (ONNX) to detect faces even in challenging lighting or angles.
- High Accuracy: Achieves 90.5% accuracy on the LFW (Labeled Faces in the Wild) dataset and 90% on Validation.
- Discriminative Embeddings: 512-dim vectors optimized for Cosine Similarity.
- Easy-to-Use API: Includes a wrapper (
inference.py) for 3-line code implementation. - Fine-tuning Ready: Includes scripts to retrain the model on your custom dataset.
🛠️ Installation
To run the pipeline, you need to install the necessary dependencies. We recommend using a virtual environment.
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118 # For CUDA support
pip install opencv-python onnxruntime-gpu huggingface_hub pillow tqdm numpy
Step 1: Download the Wrapper
- Download our helper script inference.py which handles model downloading and YOLO detection automatically.
wget https://huggingface.co/biometric-ai-lab/Face_Recognition/resolve/main/inference.py
Step 2: Create & Run Python Script
- Create a new file named run_demo.py.
- Copy and paste the code below into it.
- Make sure you have 2 images to test (e.g., face1.jpg and face2.jpg).
# File: run_demo.py
from inference import FaceAnalysis
# 1. Initialize the AI (Downloads models automatically on first run)
print("⏳ Initializing models...")
app = FaceAnalysis()
# 2. Define your images
img1_path = "face1.jpg" # <--- Change this to your image path
img2_path = "face2.jpg" # <--- Change this to your image path
# 3. Run Comparison
print(f"🔍 Comparing {img1_path} vs {img2_path}...")
try:
# Get similarity score and boolean result
similarity, is_same = app.compare(img1_path, img2_path)
print("-" * 30)
print(f"🔹 Similarity Score: {similarity:.4f}")
print("-" * 30)
if is_same:
print("✅ RESULT: SAME PERSON")
else:
print("❌ RESULT: DIFFERENT PERSON")
except Exception as e:
print(f"Error: {e}")
print("Tip: Make sure the image paths are correct!")
🎓 Training Guide
Option: Full Training (Advanced): Use train.py to train the model from scratch (ImageNet weights) on a large dataset. Step 1: Prepare Dataset
- Organize images in ImageFolder format
dataset/
├── person_1/
│ ├── img1.jpg
│ └── ...
└── person_2/
└── img1.jpg
Step 2: Run Training
python train.py \\
--data_dir ./dataset \\
--output_dir ./checkpoints \\
--epochs 50 \\
--batch_size 64 \\
--lr_backbone 8e-6 \\
--lr_head 8e-5
