A SURVEY: VIDEO SYNOPSIS TECHNIQUES

In today’s modern world, most surveillance cameras operate 24/7, but often there is not enough time and manpower to review all the video recordings. As a result, important events and activities can be missed during fast forwarding or passive camera monitoring (when cameras are not watched by security personnel.) With the increasing volume of video data, how to analyze and browse video in fast and effective way has become an urgent problem in application. Video Synopsis is an approach that helps reduce the time it takes to review long video records. It summarizes hours of video footage into minutes by simultaneously presenting all the events and activities that occurred within a specific period of time. In other words, different events that happened within a day are presented and viewed together. This allows an operator to review an hour of video in less than a minute. In this paper, we present a survey on different techniques of video synopsis.
