Abstract
With the advent of new technologies, an increasing amount of (scientific) conferences is being digitally recorded and archived for redistribution. Usually such conferences take the form of a series of talks where different speakers make use of slide-based presentations displayed as a slide-show during the speech. The data within these electronic documents can be used to improve video indexing to facilitating hence the retrieval of specific sequences within a specific video. In order to exploit such data it is however necessary to synchronize the video with the corresponding slide-show presentation. So far such synchronization has been done mainly manually. Nowadays, given the large amount of conferences being recorded, manual archiving is becoming a too time-consuming task that need to be automated. This paper presents an algorithm that automatically segments the video of the presentation and aligns each segment to the corresponding slide. Multiple tests have been done to evaluate the performance of the proposed algorithm and the obtained results, presented in the paper, prove the effectiveness of the proposed algorithm.
