Object tracking in multimedia systems

Looks at the development of techniques for tracking a user selected object through digital image sequences in multimedia system. The ability to track objects in sequences is useful in situations where the motion of objects is important (for example, to study the motion of a particular type of cell under a microscope). It is also useful when a moving object is difficult to see and needs to be highlighted. An example might be a particular object moving amongst many similar objects. A tracking tool is also of benefit to the developers of a multimedia systems to automatically `mark up´ a moving object so a user of the system can select it and manipulate it. The tool can also be used by a user to follow motion which has not been specially identified by the developer of the system
