Multimedia Summarization in Law Courts: An Environment for Browsing and Consulting

Digital videos represent a fundamental informative source of those events that occur during a penal proceedings, which thanks to the technologies available nowadays, can be stored, organized and retrieved in short time and with low cost. Considering the dimension that a video source can assume with respect to a courtroom recording, various neces- sities have been highlighted by the main judicial actors: fast navigation of the stream, ecient access to data inside and eective representation of relevant contents. One of the possible solutions to these requirements is represented by multimedia summarization aimed at deriving a syn- thetic representation of audio/video contents, characterized by a limited loss of meaningful information. In this paper a multimedia summariza- tion environment is proposed for dening a storyboard for proceedings celebrated into courtrooms.
