Belonging to the wider academic field of computer vision, videoanalytics has aroused a phenomenal surge of interest since thecurrent millennium. Video analytics is intended to solve theproblem of the incapability of exploiting video streams in realtime for the purpose of detection or anticipation. It involvesanalyzing the videos using algorithms that detect and track objectsof interest over time and that indicate the presence of events orsuspect behavior involving these objects. The aims of this book are to highlight the operational attempts ofvideo analytics, to identify possible driving forces behindpotential evolutions in years to come, and above all to present thestate of the art and the technological hurdles which have yet to beovercome. The need for video surveillance is introduced through twomajor applications (the security of rail transportation systems anda posteriori investigation). The characteristics of the videosconsidered are presented through the cameras which enable captureand the compression methods which allow us to transport and storethem. Technical topics are then discussed – the analysis ofobjects of interest (detection, tracking and recognition),“high-level” video analysis, which aims to give asemantic interpretation of the observed scene (events, behaviors,types of content). The book concludes with the problem ofperformance evaluation.
