OpenCV (Open Source Computer Vision) is an open-source library of hundreds of computer vision algorithms. OpenCV and the Viola-Jones Object Detection Algorithm WeвЂ™re going to build something similar.Д«efore we dig into the code, letвЂ™s look at some of the tools and concepts weвЂ™re going to be using. When you upload a photo of your friends, Facebook often shows it back to you with any faces highlighted, in order to prompt you to вЂњtagвЂќ people in it.

And like so many things, it also has applications in marketing.ДЇor the purposes of this tutorial, weвЂ™ll replicate a feature that you may well have used yourself if youвЂ™re a Facebook user. Some cameras use face detection for auto focussing. Some modern biometrics systems detect faces and then use facial recognition to compare those faces to images in their databases, in order to try and identify someone without having to resort to good old-fashioned passwords. There are numerous applications of face detection. (Original image from Wikipedia) Applications of Face Detection вЂ¦and hereвЂ™s what the face detection does: To illustrate the process, hereвЂ™s an example image: Facial recognition is a huge topic for another time, but face detection is the subject of this article. It shouldnвЂ™t be confused with facial recognition - i.e., trying to work out who someone is from a photograph - but itвЂ™s the first part of the process.

Computers can do it, too - it just takes some clever algorithms, reams of code and some training of the algorithms.ДЇace detection is the process of identifying faces in digital images.

Human beings have an innate ability to detect, process and recognize faces - weвЂ™re born with it.
