First of all, let's take a look at face detection. The face detection problem is actually a rather interesting problem in computer vision that researchers have worked on for many years. In 2001, Viola and Jones demonstrated how real-time, large-scale face detection can be done with minimal computational resources. This was a significant discovery at the time, as researchers seek to do real-time, large-scale face detection (for example, to monitor a large crowd in real-time). Today, face detection algorithms can be run on simple hardware such as our personal computers with just a few lines of code. In fact, as we shall see shortly, we will use OpenCV in Python to construct a face detector, using your own webcam.
There are several ...
