RESEARCH PAPER / International Journal of Computer Vision / Jan 2021
‚ÄčThis paper follows our work in 2016 and 2017 on MediaEval Predicting Media Interestingness Task. We will describe our dataset, the models that were submitted to the task, and that exist in the literature.
RESEARCH PAPER / 39th International Conference on Consumer Electronics / Jan 2021 / Wireless communication, Antennas
In this paper, we propose a novel approach for real-time radar-based human activities detection and classification. In this approach, first, the radar transceiver is mounted on the room’s ceiling leading to considerable variations of the relative received power as the subject perform the different activities. Second, to exploit the different...
RESEARCH PAPER / Pattern Analysis and Applications / Dec 2020 / ["Volumetric Imaging", "Machine learning/ Deep learning /Artificial Intelligence"]
We present a novel learning-based approach to synthesize new views of a light field image. In particular, given the four corner views of a light field, the presented method estimates any in-between view. We use three sequential convolutional neural networks for feature extraction, scene geometry estimation and view selection. Compared...
RESEARCH PAPER / Special Session at ICIP 2021 on Immersive technologies / Dec 2020
RESEARCH PAPER / Elsevier Journal on signal processing: image communication / Dec 2020 / Light Field
This paper considers the compressive sensing framework as a way of overcoming the spatio-angular trade-off inherent to light field acquisition devices. We present a novel method to reconstruct a full 4D light field from a sparse set of data samples or measurements. The approach relies on the assumption that sparse...
RESEARCH PAPER / IEEE Wireless Communications Magazine / Dec 2020 / ["5G", "Wireless communication"]
The traditional role of a communication engineer is to address the technical problem of transporting bits reliably overa noisy channel. With the emergence of 5G, and the availability of a variety of competing and coexisting wireless systems, wireless connectivity is becoming a commodity. This article argues that communication engineers in...
RESEARCH PAPER / IC3D / Dec 2020 / Computer Vision
From its Nobel prize winning discovery by Denis Gabor over half a century ago, Holography has been alternately put in the spotlight as a promising technique for its capacity of displaying 3D scenes, to be later forgotten regarding the complexity of performing holographic recording outside from optical laboratories. The later...
RESEARCH PAPER / ITU AI/ML in 5G Challenge - Grand Challenge Finale / Dec 2020 / 5G, Machine learning/ Deep learning /Artificial Intelligence, Network and Communications
This document describes the winning solution to the GNN Challenge 2020 organized by the Barcelona Neural Networking Center for the ITU Artificial Intelligence/Machine Learning in 5G Challenge. We first describe our methodology, then give the set of hyper-parameters that allowed us to achieve the best score with an average relative...
RESEARCH PAPER / IEEE GLOBECOM 2020 Industry Presentation Program / Dec 2020 / 5G, 6G, Wireless communication
Blockchain technology is a technology that jointly leverages and builds on top of a few existing techniques such as cryptography, hashing, Peer-to-Peer (P2P) networking, smart contract, and consensus protocols. Fully distributed control and management capability of the 5G/6G wireless systems may be enabled by blockchain technology, especially in the untrusted...
RESEARCH PAPER / ACM/IFIP Middleware conference 2020 - Industry track / Dec 2020 / Network and Communications, 5G, Wireless communication, Computing and Optimization
For Internet operators, on-line service providers and end-users, representative operational measurements are crucial to monitor and diagnose the performance of networks and on-line services. While numerous approaches have been proposed to measure performance, only a few works fully adopt an end-user perspective by taking measurements from within web browsers. In...
RESEARCH PAPER / IEEE Transactions on Image Processing / Dec 2020
RESEARCH PAPER / ACM/IEEE Symposium on Edge Computing workshop HotWoT / Nov 2020 / 5G, Wireless communication, Network and Communications, Computing and Optimization
This paper investigates the task management for cooperative mobile edge computing (MEC), where a set of geographically distributed heterogeneous edge nodes not only cooperate with remote cloud data centers but also help each other to jointly process tasks and support real-time IoT applications at the edge of the network. Especially,...
RESEARCH PAPER / OAI VIRTUAL WORKSHOP FALL 2020 / Nov 2020 / Haptic, 5G, 6G, Wireless communication
In this presentation we’ll talk about the development of Beam Management and describe the system attributes related to performing the initial beam establishment. We will also review the supported 3GPP requirements and limitations of the current implementation. We’ll then share some details about the beam management implementation done on the...
RESEARCH PAPER / Nov 2020 / Volumetric Imaging, Computer Graphics, Video coding
Representation of 3D scenes is gaining popularity in industry, notably for Virtual Reality, Augmented Reality, and 360° Video. The point cloud format is well suited for such representations. Indeed, point clouds can be created with a simple capture process and modest processing, enabling a real-time, end-to-end point cloud distribution chain....
RESEARCH PAPER / ISMAR / Nov 2020 / Immersive / AR/VR/MR
We describe a multi-user system enabling instant messaging in Augmented Reality. A user can get in contact with another one without requiring his/her identification number and can easily localize the person initiating the contact. It is also possible to exchange various types of personal information in a private manner. This...
RESEARCH PAPER / SMPTE annual conference / Nov 2020 / Light Field
Information captured by the eye allows the human brain to extract depth cues from the scene, to analyze them and to understand a complex 3D scene. In real life all these depth cues are naturally present at the same time and coherent. Rendering them on a display for several viewers...
RESEARCH PAPER / VRST / Nov 2020 / Immersive / AR/VR/MR
We introduce a system to assign navigation tasks to a self-moving robot using an Augmented Reality (AR) application running on a smartphone. The system relies on a robot controller and a central server hosted on a PC. The user points at a target location in the phone camera view and...
RESEARCH PAPER / Carnegie Mellon University - COMPUTER SCIENCE TECHNICAL REPORTS / Nov 2020 / Wireless communication, 5G
The emergence of edge computing introduces new complexity in the creation of distributed mobile applications. Application designers can now deploy application functionality in three or more tiers of compute infrastructure to optimize bandwidth, latency, cost, user experience and privacy for their users and their own operations. However, the diversity of...
