Face Recognition

Some face recognition scripts written with Python using OpenCV and face_recognition libraries.

Requirements

first we need to setup our environment to run the applications so for that:

Windows

1. you use windows I recommend using Anaconda for python installation because we need some tools that installing them manually is little bit hard.

2. After installing Anaconda we have Python but we need a C++ compiler because they used C++ to develop OpenCV. I recommend using Microsoft Visual C++ because it's more compatible with Windows but feel free to use anything else.

   I had Installed Visual Studio with C++ but I dont know if Runtime alone works (let me know!)

3. Download and install Cmake

4. Open Anaconda Prompt and install dlib and forge using:

   conda install -c dlib conda-forge

5. Now we can install python libraries with no problem using Anaconda Prompt:

   pip install opencv-python face_recognition imutils

Linux

• Debian/Ubuntu based distros:

  sudo apt-get install python3 python3-pip dlib gcc cmake

• RedHat/Fedora based ditros:

  sudo dnf install python3 python3-pip dlib gcc cmake

• Arch/Manjaro based distros:

  sudo pacman -S python python-pip dlib gcc cmake

Then install python libraries:

sudo pip install opencv-python face_recognition imutils

How to run

Now we are fine and all requirements are installed we can run the scripts:

Also I put some sample pictures in images directory so you can run scripts just fine but feel free to replace them.

To clone the repository: git clone https://github.com/Ainyava/FaceRecognition

Change path into it : cd FaceRecognition

Detection script

First script is just face detection without recognizing that who are those faces. I used lost.jpg sample which have many face in it.

to run this script type: python detection.py

Result:

Recognition Script

So next step is recognizing faces and for that I wrote learn_faces.py script.

for application to learn faces we need some solo pictures of persons. which inside images directory there are folders with name of persons and there are pictures of them inside those folders.

to run the script: python learn_faces.py

It will take some time to run and if nothing wrong happens it will create face_encodings file and script does not have any output.

So our application now does know about some people that we had pictures of them.

now we can give any pictures to it and see if it knows who they are?

for that I wrote recognize.py script and You can put path of images inside samples directory to see if they are Unknown or sciprt does recognize them.

Execute the script using python recognize.py

Result for Ainyava.jpg:

Last script is recognize using Webcam:

python recognize_webcam.py

Result:
