InsightFace: 2D and 3D Face Analysis Project

InsightFace project is mainly maintained by Jia Guo and Jiankang Deng.

For more information, please visit our website at https://www.insightface.ai

InsightFace 2.0 Update

InsightFace 2.0 adds PrivateFrame for local video face blur and mosaic, reference-photo selection, and editable analysis JSON through desktop, CLI, and Python workflows, plus optional RGB liveness detection for FaceAnalysis and InsightFace Server. The Python package also supports raccoon_s / raccoon_l model packages, automatic CoreML/CUDA/CPU provider selection, and reusable CoreML compilation caches. PrivateFrame defaults to Fast mode (target 15 analysis FPS).

PersonAnalysis adds person detection, face recognition, and body ReID for matching people against registered references. Use its Python API or try local videos, webcams, and RTSP streams in the desktop GUI.

For installation and use, start with the Python SDK and GUI documentation.

InsightFace Server

The new InsightFace Server provides a simple self-hosted Web UI, snake_case REST API, and Python client for detection, optional liveness checks, comparison, registration, and Person search. A single Linux x86_64 CPU or NVIDIA GPU container runs local ONNX Runtime inference and SQLite with operator-supplied, manifest-verified models. It is a simple AWS Rekognition alternative with accuracy-preserving INT8 embedding quantization and 50M+ image search on one RTX 5090 GPU.

Introduction

InsightFace is an open source 2D&3D deep face analysis toolbox, mainly based on PyTorch and MXNet.

Please check our website for detail.

The master branch works with PyTorch 1.6+ and/or MXNet=1.6-1.8, with Python 3.x.

InsightFace efficiently implements a rich variety of state of the art algorithms of face recognition, face detection and face alignment, which optimized for both training and deployment.

Quick Start

Please start with our python-package, for testing detection, recognition and alignment models on input images.
