22. Live Video Input
In this chapter, we extend the ImageFinder to live video. In particular, the ImageFinder breaks a live video stream into images and matches the images one by one. The Attrasoft ImageFinder provides the users with a tool for Live Video Matching, including:
-
Recognizing an object in a live video;
-
Reporting the time an object starts to appear;
-
Tracking an object in a video and reporting its coordinates;
-
Counting the number of frames in which the object appears; and
-
Selecting a video from a video database.
The library in this chapter supports converting live video to images. The project for this chapter is to build an Attrasoft ImageFinder that provides the users with a tool for live video matching. This chapter will only focus on how to convert live video into images. From that point on, live video recognition becomes image recognition. This chapter simply shows how to break an *.avi video file into images. From that point on, it will be an image recognition application.
