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 ...

Scrambling for Video Surveillance with Privacy

Touradj Ebrahimi

In this paper, we address the problem of scrambling regions of interest in a video sequence for the purpose of preserving privacy in video surveillance. We propose an efficient solution based on transform-domain scrambling. More specifically, the sign of s ...

Recent Advances in MPEG-7 Cameras

Touradj Ebrahimi

We propose a smart camera which performs video analysis and generates an MPEG-7 compliant stream. By producing a content-based metadata description of the scene, the MPEG-7 camera extends the capabilities of conventional cameras. The metadata is then direc ...

Fusion-based Multiview Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, we introduce a scheme for coding video surveillance camera networks. It is based on multiview and Distributed Video Coding (DVC). DVC is known for its low complexity encoders. This makes it very interesting for a wide range of applications, ...

Application Dependent Video Segmentation Evaluation - A Case Study for Video Surveillance

Touradj Ebrahimi, Elisa Drelie Gelasca

Evaluation of the performance of video segmentation algorithms is important in both theoretical and practical considerations. This paper addresses the problem of video segmentation assessment, through both subjective and objective approaches, for the speci ...

3D vision methods and selected experiences in micro and macro applications

Heinz Hügli

The paper provides considerations relative to the application of 3D vision methods and presents some lessons learnt in this respect by presenting four 3D vision tasks and discussing the selection of vision sensing devices meant to solving the task. After a ...

Tracking Video Objects in Cluttered Background

Touradj Ebrahimi

We present an algorithm for tracking video object which is based on an hybrid strategy. This strategy uses both object and region information to solve the correspondence problem. Low level descriptors are exploited to track objects regions and to cope wit ...

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 ...
