Graph-Based Approach for 3D Object Duplicate Detection

Touradj Ebrahimi, Frédéric Dufaux, Péter Vajda

In this paper, we consider the challenging problem of object duplicate detection and localization. Several applications require efficient object duplicate detection methods, such as automatic video and image tagging, video surveillance, and high level imag ...

Multi-view video segmentation and tracking for video surveillance

Touradj Ebrahimi, Frédéric Dufaux, Gelareh Mohammadi

Tracking moving objects is a critical step for smart video surveillance systems. Despite the complexity increase, multiple camera systems exhibit the undoubted advantages of covering wide areas and handling the occurrence of occlusions by exploiting the di ...

Iterative Multiview Side Information for Enhanced Reconstruction in Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux

Distributed Video Coding (DVC) is a new paradigm for video compression based on the information theoretical results of Slepian and Wolf (SW) and Wyner and Ziv (WZ). DVC entails low complexity encoders as well as separate encoding of correlated video source ...

On Evaluating Video Object Segmentation Quality: A Perceptually Driven Objective Metric

Touradj Ebrahimi, Elisa Drelie Gelasca

The task of extracting objects in video sequences emerges in many applications such as object-based video coding (e.g., MPEG-4) and content-based video indexing and retrieval (e.g., MPEG-7). The MPEG-4 standard provides specifications for the coding of vid ...

Enabling Privacy For Distributed Video Coding by Transform Domain Scrambling

Touradj Ebrahimi, Frédéric Dufaux

In this paper, a novel scheme for video scrambling is introduced for Distributed Video Coding. The goal is to conceal video information in several applications such as video surveillance and anonymous video communications to preserve privacy. This is achie ...
