A Cervix Detection Driven Deep Learning Approach for Cow Heat Analysis from Endoscopic Images

Ruiwen He, Halim Benhabiles, Feryal Windal, Gael Even, Christophe Audebert, Dominique Collard, Abdelmalik Taleb-Ahmed

In this article, we propose a new approach for the cow heat detection from endoscopic images. Our approach permits to identify on the fly the cow heat state through two successive stages, namely cervix detection then heat classification. For this purpose, images are analyzed by a Transformer based…

Towards zero-latency video transmission through frame extrapolation

Melan Vijayaratnam, Marco Cagnazzo, Giuseppe Valenzise, Anthony Trioux, Michel Kieffer

In the past few years, several efforts have been devoted to reduce individual sources of latency in video delivery, including acquisition, coding and network transmission. The goal is to improve the quality of experience in applications requiring real-time interaction. Nevertheless, these efforts…

[Invited tutorial] Soft Video Delivery: Getting seamless quality adaptation in mobile and latency-critical applications

Anthony Trioux, François-Xavier Coudoux, Marco Cagnazzo, Michel Kieffer

Conventional video coding and transmission systems are currently based on digital video compression (e.g., HEVC) on a suitable network protocol (802.11, 4G, or 5G) and rely on Shannon separation theorem. However, they suffer from some inherent limitations when the video content is transmitted over…

Utilization of Catechol End-Functionalized PMMA as a Macromolecular Coupling Agent for Ceramic/Fluoropolymer Piezoelectric Composites

Vincent Bouad, Alexandre Fadel, Saj Mohan, Arthur Hamieh, Jean-François Tahon, Joël Lyskawa, Patrice Woisel, Antonio Da Costa, Anthony Ferri, Rachel Desfeux, Freddy Ponchel, Denis Remiens, Vincent Ladmiral, Sophie Barrau

An approach based on the use of a macromolecular coupling agent and the aim to improve the interfacial adhesion between piezoelectric ceramics and piezoelectric polymer matrix in piezoelectric composites is presented. Poly(methyl methacrylate) (PMMA) bearing a catechol moiety was used as a…

Event-Driven ECG Classification using Functional Approximation and Chebyshev Polynomials

Maryam Saeed, Olev Martens, Benoit Larras, Antoine Frappé, Deepu John, Barry Cardiff

Level-crossing ADCs reduce the size of data streams in wearable devices. However, in the context of electrocardiogram (ECG) signals, such an event-driven data source results in a variable length two-dimensional (time-amplitude tuples) data vector for each ECG beat. It is difficult to apply many…

Study of the influence of RGB and Lab color spaces on the performance of multifocus image fusion techniques

Sarra Babahenini, Fella Charif, Abdelmalik Taleb-Ahmed

In order to create a single image, multifocus image fusion brings together the important details and focused areas of the input multifocus images. Diverse camera depths of the field are used to capture these multi-focus images. Spatial domain focusing measurement has been used to introduce various…

Elastic metasurface made of elliptic shape pillars for acoustic wave focusing

Bahram Djafari-Rouhani, Laurent Carpentier, Yan Pennec

We numerically propose the design of a metasurface for focusing the flexural Lamb waves propagating on a plate. The metasurface consists of a line of pillars of elliptic shape with a gradient in their ellipticity. We first determine an elliptic pillar that allows the superposition of two resonances…

Deep Learning-based receiver for Uplink in LoRa Networks with Sigfox Interference

Angesom Ataklity Tesfay, Eric Pierre Simon, Sofiane Kharbech, Laurent Clavier

The Internet of Things faces a significant scaling issue due to the rapid growth of the number of devices and asynchronous communications. Different technologies in the license-free industrial, scientific, and medical (ISM) band have been widely deployed to fill this gap. LoRa and Sigfox are the…
