Human activity detection and recognition

The rapid growth in size of storage devices allows us to store hours, days or even months of video data. Watching through and analyzing videos of such length is no longer feasible. In order to summarize or index videos (for search purposes) we need to develop algorithms which detect and classify events happening in the video without human supervision. To identify and describe various types of events we seek important features and ways of extracting/learning them from the video data.
