# 🩺 Finger Vein Feature Extractor using MobileNet
This pretrained model is designed for **finger vein recognition**. It uses a **MobileNet-based feature extractor** trained on finger images to extract deep biometric features.
## 🔧 How It Works:
- The model first extracts features from finger vein images using **MobileNet**.
- These features are then used to form **image pairs**.
- A **deep neural network** (e.g. Siamese) is trained on these pairs to learn a similarity metric.
- Finally, the system classifies whether two finger vein images belong to the **same person** or not.
## 📦 Use Cases:
- 🔐 Biometric authentication systems
- 🔍 Finger vein matching or verification
- 🧬 Medical/Forensic identification tasks
## 🖼️ Input:
- RGB finger vein image (resized to **224×224**)
- Normalized to [0, 1]
## 📤 Output:
- Feature vector (if using encoder only)
- Or: **Match / No-match** decision (in Siamese setup)
## 💾 Model Format:
- `model.keras` — Keras format for MobileNet feature extractor
