Introduction

Nowadays, thanks to the advances in the technology fields, smart electronic devices, automation, computer science, artificial intelligence (AI), and embedded systems, we are capable to build more and more complex systems that incorporate many different features. One important feature that a lot of new systems and products of different industry areas try to incorporate is the capability to detect motion.

Let us start by defining motion detection as the process of detecting a change in the position of an object relative to its surroundings or a change in the surroundings relative to an object. With the proliferation of low-cost digital cameras able to shoot video and the popularization of modern devices to incorporate cameras, it is possible to use the output of such a camera to detect motion in its field of view using software algorithms. This solution is particularly attractive when the intent is to record video triggered by motion detection, as no hardware beyond the camera and computer is needed.

One of the most important areas that require their systems to have motion detection capability is Video Surveillance. In video surveillance, motion detection refers to the capability of the surveillance system to detect motion and capture the events. Motion detection is usually a software-based monitoring algorithm that, when it detects motions will signal the surveillance camera to begin capturing the event. Modern motion detection surveillance systems with AI incorporated can analyze the type of motion to see if it warrants an alarm or not, for example by tracking the motion trajectory of the object or by identifying the object under movement.
