In this paper, we present our eSur (Event detection system on SURveillance video) system,
which is derived from TRECVID'09 surveillance tasks. Currently, eSur attempts to detect two …

In this paper, we describe our eSur system and experiments performed for the surveillance
event detection task in TRECVID 2009. In the experiments, we addressed the detection …

Event detection in crowded surveillance videos is a challenging yet important problem. In
this paper, we present our eSur (Event detection system on SURveillance video) system …

This paper is a summary of the 2008 TRECVid Event Detection evaluation track. TRECVid is
a laboratory-style evaluation that aims to model real world situations or significant …

Event detection have long been a fundamental problem in computer vision society. Various
datasets for recognizing human events and activities have been proposed to help …

Summary TRECVID Multimedia Event Detection offers an interesting but very challenging
task in detecting highlevel complex events (Figure 1) in user-generated videos. In this paper …

In this paper we perform event analysis on a challenging surveillance dataset without any
artificial events. We analyze low-level and high-level features such as motion vectors …

In this paper, we describe our system for interactive and retrospective surveillance event
detection task in TRECVid 2012. We focus on pair-wise events (eg, PeopleMeet …

We discuss an event detection approach based on local feature modeling, which is based
on spatio-temporal cuboids and perspective normalization (QMUL-ACTIVA 3/p-baseline 1) …

We present a retrospective system for event detection in surveillance videos automatically,
which is built on the Gatwick development data. It is an enhanced version of the …
