"The 3GPP has standardized the 5G New Radio (NR) sidelink (SL) technology that enables direct device-to-device communications. SL will be key in realizing several high-speed, low-latency V2X applications, such as automated driving. To meet these applications’ high data rate requirements, operating SL at mmWave and sub-THz frequencies will be essential....

"The limited contrast and colors in SDR have historically compelled content producers to make hard choices, whereas HDR offers them the possibility to show more - meaning telling stories with greater freedom and flexibility. Even so, HDR content presents a challenge of its own: The wide variation in capabilities among...
RESEARCH PAPER / SMPTE Motion Imaging Journal / Aug 2023
"The media and entertainment industry consumes a significant amount of energy to create, distribute as well as to present video content to consumers. A large proportion of this energy is used by display devices, notably by the 1.9+ billion displays installed in consumers' homes globally. The production of light within...

RESEARCH PAPER / IEEE International Conference on Network Softwarization (NetSoft 2023) / Jun 2023
This paper proposes a novel orchestration scheme to achieve optimal network resource allocation in Application Aware Networking (AAN) using wireless contextual information. We prove AAN to be NP-hard and show how our formulation enhances remote driving of a robot in a real wifi-based scenario, meeting latency constraints.
RESEARCH PAPER / IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR 2023) / Jun 2023
"This paper proposes a novel framework to compress face-centric videos for both human viewing and machine analysis. Our system uses three coding branches to combine the power of generic face prior learning with data-dependent detail recovery. The generic branch embeds faces into a discrete code space described by a learned...
RESEARCH PAPER / ACM Multimedia Systems / Jun 2023
Film grain which used to be a by-product of the chemical processing in the analog film stock, is a desirable feature in the era of digital cameras. Besides participating to the artistic intent during content creation, film grain has also interesting properties in the video compression chain such as its...
RESEARCH PAPER / Quality and User Experience (Springer) / Jun 2023
"Efficient objective and perceptual metrics are valuable tools to evaluate the visual impact of com- pression artifacts on the visual quality of volumetric videos (VVs). In this paper we present some of the MPEG group efforts to create, benchmark and calibrate objective quality assessment metrics for volumetric videos represented as...
RESEARCH PAPER / IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2023) / Jun 2023
"With the advent of new 3D scanning technologies, point clouds have become a crucial way to depict real and virtual objects/scenes. Point clouds represent the continuous surfaces of underlying object/scene through a collection (usually millions) of discrete, irregular, and often sparsely distributed 3D samples on the surface of the objects....
RESEARCH PAPER / IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2023) / Jun 2023
Point cloud compression is necessary to enable the deployment of virtual and mixed reality applications, since the number of points in a single character can be in the order of millions. There exist different learning-based approaches to compress the geometry of point clouds, on the other hand the compression of...

"Already approved PID1408 The increasing popularity of XR applications is driving the media industry to explore the creation and delivery of new immersive experiences, addressing the key challenge of real video content manipulation. The proposed session addresses challenges and presents key technologies leveraging open standards for large scale distribution. A...
RESEARCH PAPER / IEEE International Symposium on Circuits and Systems (ISCAS 2023) / May 2023
Deep neural networks have been recently applied to point cloud compression (PCC). The features extracted via deep neural networks are essential for compression performance. Different from high level tasks such as point cloud classification or segmentation which homogenizes descriptors within same classes, PCC requires low level features discriminative for point...

ETSI Multi-access Edge computing (MEC) main purpose is to improve latency and bandwidth consumption by keeping local traffic local while providing computing resources near the end-user. Despite its clear benefits, the next-generation of hyper-distributed applications (e.g., edge robotics, augmented environments, or smart agriculture) will exacerbate latency and bandwidth requirements, posing...

"In the context of climate change, reducing the environmental impact of the video chain is a requirement for any actor in the field. Each step, from production, encoding, transmission, to decoding and display on screens participates to the overall energy consumption, but it is commonly agreed that displays are the...
