Abstract
Automatic annotation of recorded lectures includes the annotation of recorded presentations as presented on a computer screen during a presentation. Such annotation is accomplished with metadata that indicates the original slide and the time in the presentation that the slide was presented. Registration of the presentation tags the presentation with this metadata, which uniquely identifies the presentation and each slide. The metadata enables future searching of the recorded presentation for the annotation, such that segments of recorded presentations in which the slide was presented can be recalled. The searching function can also be used in an integrated system with other applications to enable recall of segments of relevant recorded presentations.
