Video summarization of surveillance cameras

The number of video surveillance cameras has increased by a large amount in recent years. There is therefore a need to process the captured videos such that human operators can quickly review the activities recorded by a camera over a long period of time. We propose in this paper an approach for producing video summaries, an abbreviated video preserving the important elements of interest. We introduce a dataset as well as three evaluation metrics for quantifying the performance of a video summary with respect to compression length, the amount of activity retained and the amount of activity that is packed into each frame of the summary.
