Abstract
A video object detection system based on region transition includes a video acquiring unit, a user interface unit and a control module. The video acquiring unit is utilized for acquiring a video frame. The user interface unit is configured to provide a user to define at least one detection region with a set of image pixels on the acquired video frame and to define at least one region transition rule for identifying video objects of interest. Each detection region is represented with a set of image pixels. The control module is utilized for detecting position of a target video object and determining whether a moving trajectory of the target video object matches the at least one region transition rule.
