Le groupe international d\u2019experts en compression d\u2019image (JPEG) a d\u00e9velopp\u00e9 un nouveau standard de compression des images plus rapide et moins \u00e9nergivore. JPEG XS vise les applications telles que la r\u00e9alit\u00e9 virtuelle, la r\u00e9alit\u00e9 augment\u00e9e, l\u2019imagerie spatiale, les voitures autonomes et l\u2019\u00e9dition de films par des professionnels.<\/strong><\/h4>\n

Le premier standard JPEG a \u00e9t\u00e9 cr\u00e9\u00e9 il y a 25 ans pour stocker et envoyer les images rendues tr\u00e8s l\u00e9g\u00e8res. Aujourd\u2019hui, entre 10 et 15 milliards d\u2019images en format JPEG sont partag\u00e9es quotidiennement sur les r\u00e9seaux sociaux dans le monde entier. Le Joint Photographic Experts Group (JPEG<\/a>) vient de d\u00e9voiler un nouveau format de fichier JPEG. Baptis\u00e9e JPEG XS, cette nouvelle technologie est moins \u00e9nergivore et permettra d’envoyer des images et des vid\u00e9os de qualit\u00e9 sup\u00e9rieure avec des d\u00e9lais ultra-courts \u00e0 travers des r\u00e9seaux \u00e0 larges bandes passantes comme la 5G et le WIFI.<\/p>\n

Le Joint Photographic Experts Group est un comit\u00e9 international dirig\u00e9 par Touradj Ebrahimi, professeur \u00e0 la facult\u00e9 des Sciences et Techniques de l\u2019Ing\u00e9nieur (STI<\/a>) et responsable Multimedia Signal Processing Group \u00e0 l\u2019EPFL<\/a>. \u00ab\u00a0Pour la premi\u00e8re fois dans l\u2019histoire du codage d\u2019images, nous compressons moins pour mieux pr\u00e9server la qualit\u00e9, et r\u00e9duisons les d\u00e9lais tout en consommant moins d\u2019\u00e9nergie \u00bb, explique-t-il dans un communiqu\u00e9<\/a>. \u00ab\u00a0Nous voulons \u00eatre plus intelligents. Utiliser moins de ressources, et de fa\u00e7on plus ad\u00e9quate. Cela repr\u00e9sente un changement de paradigme.\u00a0\u00bb La compression JPEG r\u00e9duit par 10 la taille des images, tandis que JPEG XS propose une compression par un facteur 6 au maximum.<\/p>\n

JPEG XS sera utilis\u00e9 dans un vaste \u00e9ventail d’applications. \u00ab\u00a0Dans le futur imm\u00e9diat, JPEG XS fonctionnera d\u2019abord pour des applications professionnelles telles que l\u2019\u00e9dition de films, l\u2019imagerie spatiale et les cam\u00e9ras \u00e0 usage professionnel. Puis ce sera le tour des produits grand public qui comprennent les voitures autonomes, la r\u00e9alit\u00e9 virtuelle, la r\u00e9alit\u00e9 augment\u00e9e, les connections sans fils entre appareils multim\u00e9dias et moniteurs TV ou projecteurs,\u00a0\u00bb explique Touradj Ebrahimi.<\/p>\n","protected":false},"excerpt":{"rendered":"
