Face detection in pictures and webcam using OpenCV in Python

How to use the project

You can use this project by cloning the repository with Git command:

git clone https://github.com/anhnguyenphung/face_detection

Then move to the directory that you just have cloned by running the following command in the terminal:

cd face_detection

Detect faces in pictures

To detect faces in a picture, run the following command in the terminal:

python face_detection.py image_file

where image_file is the location of the image file (in JPG or PNG format) that you want to detect faces. There are some example pictures in the folder example_pictures of the repository, or you can choose your own pictures, to test out.

For example, python face_detection.py example_pictures/example_1.jpg would produce the following output:

python face_detection.py example_pictures/example_2.jpg would produce the following output:

Detect faces in webcam

To detect faces in webcam, run the following command in the terminal:

python webcam_face_detection.py 

For example, when I ran the above command on my terminal, I had the following output:

Conclusion

From this project, I have learned how to use OpenCV library in Python for face detection, thanks to blog posts from Real Python.
