Face recognition and live estimation on Raspberry Pi 4B with average FPS around 20 and 2800+ faces loaded.

Update

2021-07-22: reworked cmakefiles and livefacereco code, added ParallelVideoCapture module and DatasetHandler module. y9luiz

2020-09-05: with the help of konglingzheng, add ncnn lib of nano, please simply change the path in the cmakelist when other platform is used.

2020-08-26: add ncnn libs (ubunutu, arm64-v8a, armeabi-v7a, and RaspberryPi4B ) to include folder

Introduction

The project implements Face Recognition and Face Anti Spoofing on Raspberry pi with the models transformed to ncnn. Besides, the whole project is designed as an entrance guard system by reading face images in the img folder and determining whether the input face is in the dataset by Arcface. The most interesting function is that it is capable to estimate whether the face getting from the camera is real just relaying on the input image instead of with the help of human body sensors or temperature sensors. As a result, it can avoid the situation of deceived by false faces, including printed paper photos, the display screen of electronic products, silicone masks, 3D human images, etc.

• Neural Network Inference

  ncnn

• Detection:

  mtcnn

• Recognition:

  MobileFaceNet

• Anti-Spoofing:

Face-Anti-Spoofing

• The program was run with 2859 faces in img folder, which is enough for a moderate entrance guard system.

• There is only one image of me(not wearing a mask) in the database, and it is capable to recognize me when wearing a mask(not robust enough). The performance can be improved when retinaface is used as the Detector(TODO).

• The average FPS is around 20, and it successfully recognized me from the database.

• The number in cyan indicates the score for face recognition, and the number in yellow shows the confidence of live estimation.

Dependency

• OpenCV >= 4.0.0

---

Preparation

• OpenCV

  Building OpenCV on Raspberry Pi might be slightly different from that in other linux systems. If you met some problem, you may find this website helpful.

• project_path:

  set project_path in livefacereco.hpp into your own

• face database:

  set record_face=true in livefacereco.hpp to add your face to database, you can rename it in img folder.

---

Run

make sure you have changed project_path to your own

mkdir build
cd build
cmake ..
make -j4
./LiveFaceReco
