In this chapter, we will explore the vast topic of object tracking, which is the process of locating a moving object in a movie or video feed from a camera. Real-time object tracking is a critical task in many computer vision applications such as surveillance, perceptual user interfaces, augmented reality, object-based video compression, and driver assistance.

Tracking objects can be accomplished in several ways, with the optimal technique being largely dependent on the task at hand. We will learn how to identify moving objects and track them across frames.
