Abstract:

Detecting and tracking objects are the most prevalent and challenging tasks,which will be wildly used in video monitoring,human and computer interaction as well as military fields. Realtime,accurately and steadily expressing the objects are the key problems,whereas abrupt object motion,changing appearance patterns of both the object and the scene may lead to low accuracy.In this paper, tracking problem is categorized into two parts:object detection and tracking. Besides,the scene understanding is considered in visual tracking.In the end,the paper points out the drawbacks of the existing visual tracking systems,and prospects the future researches.
