gfram 2.0.0

Professional geometric face recognition library with AI-powered matching

GFRAM - Geometric Face Recognition and Matching

Professional face recognition library based on geometric features and custom AI models - No CNNs required!

🌟 Key Features

• Pure Geometric Approach: 150+ geometric features from facial landmarks
• Custom AI Architecture: GeometricTransformer and Geometric GNN models
• No CNN Dependency: Lightweight and highly interpretable
• High Performance: Competitive accuracy with traditional deep learning methods
• Cross-Platform: Works on Windows, macOS, and Linux
• Easy to Use: Simple, intuitive API

🎯 Scientific Innovation

GFRAM introduces novel geometric descriptors for face recognition:

1. Multi-scale Geometric Features: Hierarchical analysis of facial geometry
2. Topological Features: Persistent homology for structural analysis
3. Geometric Transformer: Self-attention on geometric relationships
4. Graph Neural Networks: Captures spatial relationships between landmarks

📦 Installation

Basic Installation

pip install gfram

Full Installation (with all features)

pip install gfram[all]

🚀 Quick Start

Face Recognition in 3 Lines

import gfram

# Initialize and create database
recognizer = gfram.Recognizer()
recognizer.create_database()

# Add people
recognizer.add_person("John", ["john1.jpg", "john2.jpg"])
recognizer.add_person("Jane", ["jane1.jpg", "jane2.jpg"])

# Recognize
result = recognizer.recognize("test.jpg")
print(f"Identity: {result['faces'][0]['name']}")

Using Geometric Features Only

import gfram

# Initialize components
detector = gfram.FaceDetector()
extractor = gfram.GeometricFeatureExtractor()

# Detect and extract
import cv2
image = cv2.imread("photo.jpg")
faces = detector.detect(image)
features = extractor.extract(faces[0]['landmarks'])

print(f"Extracted {len(features)} features")

Using AI Models

import gfram
import torch

# Create model
model = gfram.create_geometric_transformer("base", num_classes=100)

# Forward pass
landmarks = torch.randn(1, 468, 3)
logits, embedding = model(landmarks)
