Abstract:

A system for automatically tracking objects through a video sequence uses a method which automatically tracks an object by estimating the location of the object in a subsequent frame, comparing test windows in the subsequent frame with an object window encompassing the object in the original frame, and selecting the best match window which is most similar to the object window. The location of the best match window corresponds to the location of the object in each frame of the video sequence. The resulting location information can be combined with the video sequence to create interactive video applications in which an user of the application can select individual objects in the interactive video sequence.
