You can detect faces using Python. These faces can be in a still image, video or web cam feed.
All of this can be done with only a few lines of code!
The method used here uses Machine Learning. Machine Learning is a part of Artificial Intelligence, that uses data to make new predictions.
In this case you want to predict if there's a face in the image.
Getting started
You will need Python 3.x and OpenCV 2 installed. You'll also need a cascade file, which OpenCV uses to detect faces.
OpenCV can be installed with the Python package manager:
pip3 install opencv-python
You'll also need the runtime opencv package.
Face detection uses the machine learning approach: given statistical examples, predict if there is a face in the image.
