Features

• Face Detection — RetinaFace, SCRFD, YOLOv5-Face, and YOLOv8-Face with 5-point landmarks
• Face Recognition — ArcFace, MobileFace, and SphereFace embeddings
• Facial Landmarks — 106-point landmark localization
• Face Parsing — BiSeNet semantic segmentation (19 classes)
• Gaze Estimation — Real-time gaze direction with MobileGaze
• Attribute Analysis — Age, gender, race (FairFace), and emotion
• Anti-Spoofing — Face liveness detection with MiniFASNet
• Face Anonymization — 5 blur methods for privacy protection
• Hardware Acceleration — ARM64 (Apple Silicon), CUDA (NVIDIA), CPU

Installation

# Standard installation
pip install uniface

# GPU support (CUDA)
pip install uniface[gpu]

# From source
git clone https://github.com/yakhyo/uniface.git
cd uniface && pip install -e .

Quick Example

import cv2
from uniface import RetinaFace

# Initialize detector (models auto-download on first use)
detector = RetinaFace()

# Detect faces
image = cv2.imread("photo.jpg")
faces = detector.detect(image)

for face in faces:
    print(f"Confidence: {face.confidence:.2f}")
    print(f"BBox: {face.bbox}")
    print(f"Landmarks: {face.landmarks.shape}")
