21. Video Input
The ImageFinder breaks a video file into frames and matches the frames one by one. The Attrasoft ImageFinder provides the users with a tool for Video Matching, including:
-
Recognizing an object in a 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.
This library supports only *.avi files. This chapter simply shows how to break an *.avi video file into images. From that point on, it will be an image recognition application.
