Install Environment

(on x86 device)

pip install -r requirements.txt

(on arm device)

Notice: Install pytorch from https://forums.developer.nvidia.com/t/pytorch-for-jetson-version-1-9-0-now-available/72048 and torchvision in similar way.

Clone

git clone https://github.com/ojipadeson/faceRecognition

Store some photos

In order to recognize you, store some of your photos (>=1) into /face directory, and name as :

/face
   your_name00.jpg
   your_name01.jpg
   ...
   # similar for other people
   David00.jpg
   Selina00.jpg
   Selina01.jpg
   ...

Preprocessing

python face_process.py

Run

python test.py

Optional Arguments(Can Skip)

-h help command

---

-r record every frame of the output video when the system is running

---

-n set a simple logic that we gather n images' information before coming to a prediction for Anti-Spoofing

-c the confidence threshold for above logic.

For example, -c 0.8 -n 10 means when over 8 of 10 pictures are tested alive then the system will give the result True Face. Similarly, Fake Face will be given when over 8 of 10 pictures are tested Fake If the result don't belong to above 2 situation, video stream will show Considering...

---

-p when result is neither surely real nor surely fake for a relatively long time, it's very possible that the system is under attack. With this command, system will lock when samples are difficult to predict

---

-t the tolerance threshold for face recognition. When face distance is above this threshold, the system will treat it as Unknown Face

---

-f show fps on the video output, and give a plot for fps at all time after system exit

-m show the running time(s) of every part of the system after exit

---

Concrete usages are as follows:

usage: test.py [-h] [-r] [-p] [-n NUMBER] [-c CONFIDENCE] [-t TOLERANCE] [-f]
               [-m]

optional arguments:
  -h, --help            show this help message and exit
  -r, --record          record the video
  -p, --protect         protect system from difficult samples
  -n NUMBER, --number NUMBER
                        number of test time for one face
  -c CONFIDENCE, --confidence CONFIDENCE
                        minimal confidence for multi-test
  -t TOLERANCE, --tolerance TOLERANCE
                        tolerance for minimal face distance
  -f, --fps             record frame rate
  -m, --monitor         monitor every part's performance

System Exit

1. Video Windows On Top
2. Press Q

• If you enable system protection by command -p or --protect, and encounter system lock(screen grayed out), press P to unlock

• If not exit immediately, try pressing several more times
