Video hypermedia authoring using automatic object tracking

ABSTRACT Video hypermedia systems enable users to retrieve information related to an object by selecting it directly in a video sequence.In video hypermedia systems, users must locate an anchor position according to the motion of the object. But it is verylaborious to locate an anchor to its suitable position according to the motion of the object. We have proposed a new automaticobject tracking method and implemented it to the system. A feature of this method is that it includes various automatic errorcorrection algorithms. We evaluated this system on effectiveness on reducing human operations. As a result, the number ofoperations reduced to 30.3% of the former method, and the time of operations reduced to 60.1% of the former method.Keywords: hypermedia, pattern recognition, object tracking, video database 1. INTRODUCTION It is required in video database systems that users can retrieve information related to moving objects in video sequences. Wecall such video retrieval system as video hypermedia systems
