Navigation domain representation for interactive multiview imaging

Pascal Frossard, Thomas Maugey

Enabling users to interactively navigate through different viewpoints of a static scene is a new interesting functionality in 3D streaming systems. While it opens exciting perspectives towards rich multimedia applications, it requires the design of novel r ...

Rate-distortion analysis of multiview coding in a DIBR framework

Pascal Frossard, Thomas Maugey

Depth image based rendering techniques for multiview applications have been recently introduced for efficient view generation at arbitrary camera positions. Encoding rate control has thus to consider both texture and depth data. Due to different structures ...

Classification of unions of subspaces with sparse representations

Pascal Frossard, Alhussein Fawzi

We propose a preliminary investigation on the benefits and limitations of classifiers based on sparse representations. We specifically focus on the union of subspaces data model and examine binary classifiers built on a sparse non linear mapping (in a redu ...

Graph-based representation and coding of multiview geometry

Pascal Frossard, Thomas Maugey

We propose a new approach for describing the geometry information of multiview image representations. Rather than transmitting the raw geometry of the scene, under the form of depth information, we build a graph that represents the connections between corr ...

Joint Reconstruction of Multi-view Compressed Images

Pascal Frossard, Vijayaraghavan Thirumalai

The distributed representation of correlated multi-view images is an important problem that arise in vision sensor networks. This paper concentrates on the joint reconstruction problem where the distributively compressed correlated images are jointly decod ...

Interactive Free Viewpoint Video Streaming Using Prioritized Network Coding

Pascal Frossard, Nikolaos Thomos, Laura Toni

In free viewpoint applications, the images are cap- tured by an array of cameras that acquire a scene of interest from different perspectives. Any intermediate viewpoint not included in the camera array can be virtually synthesized by the decoder, at a qua ...

Performance Bounds for Sensor Data Gathering by Coding in Finite Fields

Pascal Frossard, Tamara Tosic

We address the problem of data gathering in adhoc networks. We propose a novel framework where sensor signals are quantized and mapped to a finite field. The network nodes then combine the data from different sensors to form messages that are transmitted t ...

Distributed sensor failure detection in sensor networks

Pascal Frossard, Tamara Tosic, Nikolaos Thomos

We investigate the problem of distributed sensors' failure detection in networks with a small number of defective sensors, whose measurements differ significantly from neighbouring sensor measurements. We build on the sparse nature of the binary sensor fai ...

Method of providing scalable video coding (svc) video content with added media content

Pascal Frossard, Jakov Cakareski

A method of providing SVC video content with added media content, comprising the steps of: receiving an original video content transmitted from a remote site in a bit stream and including original video encoding parameters decoding said original video enco ...

Correlation Estimation from Compressed Images

Pascal Frossard, Vijayaraghavan Thirumalai

This paper addresses the problem of correlation estimation in sets of compressed images. We consider a framework where images are represented under the form of linear measurements due to low complexity sensing or security requirements. We assume that the i ...

Growth Codes: Intermediate Performance Analysis and Application to Video

Pascal Frossard, Rethnakaran Pulikkoonattu, Nikolaos Thomos

Growth codes are a subclass of Rateless codes that have found interesting applications in data dissemination problems. Compared to other Rateless and conventional channel codes, Growth codes show improved intermediate performance which is particularly usef ...

Optimized MVC Prediction Structures for Interactive Multiview Video Streaming

Pascal Frossard, Ana Karina De Abreu Goes

The Multiview Video Coding (MVC) standard efficiently compresses multiview video by considering spatial, temporal and interview correlations. This letter studies the impact of the MVC interview prediction structure on both the transmission and the overall ...

Markov Decision Process Based Energy-Efficient On-Line Scheduling for Slice Parallel Video Decoders on Multicore Systems

Pascal Frossard, David Atienza Alonso, Karim Kanoun

We consider the problem of energy-efficient on-line scheduling for slice-parallel video decoders on multicore systems. We assume that each of the processors are Dynamic Voltage Frequency Scaling (DVFS) enabled such that they can independently trade off per ...

Distributed average consensus with quantization refinement

Pascal Frossard, Effrosyni Kokiopoulou, Ntorina Thanou, Ye Pu

We consider the problem of distributed average consensus in a sensor network where sensors exchange quantized information with their neighbors. We propose a novel quantization scheme that exploits the increasing correlation between the values exchanged by ...

Graph-Based vs Depth-Based Data Representation for Multiview Images

Pascal Frossard, Thomas Maugey

In this paper, we propose a representation and coding method for multiview images. As an alternative to depth-based schemes, we propose a representation that captures the geometry and the dependencies between pixels in different views in the form of connec ...

Learning Pattern Transformation Manifolds for Classification

Pascal Frossard, Elif Vural

Manifold models provide low-dimensional representations that are useful for analyzing and classifying data in a transformation-invariant way. In this paper we study the problem of jointly building multiple pattern transformation manifolds from a collection ...
