Detecting Abandoned Luggage Items in a Public Space

Daniel Gatica-Perez, Kevin Smith, Pedro Manuel Da Silva Quelhas

Visual surveillance is an important computer vision research problem. As more and more surveillance cameras appear around us, the demand for automatic methods for video analysis is increasing. Such methods have broad applications including surveillance for ...

Smart video surveillance system preserving privacy

Touradj Ebrahimi, Frédéric Dufaux

In this paper, we present a smart video surveillance system based on standard technologies and wired or wireless IP networking. The key novelty of the system is that it protects the privacy of people under surveillance. More specifically, a video analysis ...

Critical Video Quality for Distributed Automated Video Surveillance

Large-scale distributed video surveillance systems pose new scalability challenges. Due to the large number of video sources in such systems, the amount of bandwidth required to transmit video streams for monitoring often strains the capability of the netw ...

Surveillance Video for Mobile Devices

Touradj Ebrahimi

In this paper, we present a video encoding scheme that uses object-based adaptation to deliver surveillance video to mobile devices. The method relies on a set of complementary video adaptation strategies and generates content that matches various applianc ...

Real-Time Generation of Annotated Video for Surveillance

Touradj Ebrahimi

We present a system that generates annotated video in realtime. Moving objects are first automatically extracted by means of video analysis and then coded using MPEG4. Moreover, an MPEG7 description of object features is generated. This description is us ...

Trajectory Analysis for Sport and Video Surveillance

Jacques Jacot, Florian Luisier, Pierre Roduit

In video surveillance and sports analysis applications, object trajectories offer the possibility of extracting rich information on the underlying behavior of the moving targets. To this end we introduce an extension of Point Distribution Models (PDM) to a ...

Video surveillance using JPEG 2000

Touradj Ebrahimi, Frédéric Dufaux

This paper describes a video surveillance system which is composed of three key components, smart cameras, a server, and clients, connected through IP-networks in wired or wireless configurations. The system has been designed so as to protect the privacy o ...

The Security and Privacy of Smart Vehicles

Jean-Pierre Hubaux, Jun Luo, Srdan Capkun

Road safety, traffic management, and driver convenience continue to improve, in large part thanks to appropriate usage of information technology. But this evolution has deep implications for security and privacy, which the research community has overlooked ...

BEHAVIORAL FILTERING OF HUMAN TRAJECTORIES FOR AUTOMATIC-MULTI-TRACK INITIATION

Michel Bierlaire, Jean-Philippe Thiran, Gianluca Antonini

In this paper we describe a new approach for the multitrack initiation problem. We propose an extensive use of the top-view reconstruction of the scene to solve the detection step in tracking pedestrians. We leave a large set of starting hypothetical movin ...

Trajectories clustering in ICA space: an application to automatic counting of pedestrians in video sequences

Jean-Philippe Thiran, Gianluca Antonini

In this paper we propose a method for the automatic counting of pedestrians in video sequences for (automatic) video surveillance applications. We analyse the trajectory data set provided by a detection/tracking system. When using classical target detectio ...
