Chapter 7. Digital Video-Based Motion Detection

Similar to the last few chapters, this chapter is a step-by-step tutorial on converting a low-cost USB web camera and the BeagleBoard into a motion detector. This goal will be achieved by developing an algorithm of tracking a moving object in a sequence of video frames.

This chapter covers the following topics:

• Video input: A USB Logitech C310 web camera

• Video acquisition: A software module in Simulink to access the video frame

• Motion detection algorithm: A video processing algorithm to identify and detect the moving target

• Parameter adjustment: How to configure the system parameter to achieve a better application effect

By the end of this chapter, you will have a valid prototype of a motion detection system, based on which you can develop a well-functioning home security, vision analysis, or traffic monitoring application. All the evaluations will be performed on the BeagleBoard, which is capable of doing onboard computation for this kind of video...
