20 December 1999 Maintaining hotspots: using object tracking techniques to automate HyperVideo

Hypervideo is the natural evolution of Hypertext. Interlinking images and text in modern Hypertext pages is well understood and widely used in commercial services. Links from text to images and image to text are used interchangeably and there is a plethora of development environments in the market today.Links from video sequences out to other pieces of information are not currently widely available mainly because of the temporal nature of any defined hotspots. For example in a video commercial about cars a hotspot defined around a car model featured in the commercial has to 'move' with or rather track the car. The obvious way of defining such a hotspot is to use a mixture of conventional image mapping techniques assisted by manual mapping of the required regions in every frame. This approach is very cumbersoem and time consuming so will never have widespread commercial appeal.
