Forensics Usage of Video-Surveillance and Associated (Meta) Data - Forensic Science & Medicine

Forensic video analysis is the offline analysis of video aimed at finding video or digital evidence during an investigation. In order to find video evidence during an investigation (terrorism, kidnapping, homicide, ...), investigators need to analyze and watch large amounts of video data (equivalent to a high number of video hours). Despite the powerful existing techniques and algorithms for  video  processing, investigators are still facing  many  problems including  the  large  volume of video data and time consuming. The correct interpreta-tion of videos requires a set of accurate miscellaneous data called the metadata. In this  paper, we  focus on the contribution that  can come from the correlation between  video  surveillance, metadata and context infor-mation.  Such  a  contribution can be demonstrated at the end of the projects we are currently working on in collaboration with the police services.
