Bonjour, Nous recherchons un développeur C/C++ openCV pour un projet de vision industrielle. Le but du projet et de programmer en C++ un algorithme pour détecter la position d'objet identique multiple superposé. L'algorithme doit être générique , rapide et Independent de l'objet (formes simple). Nous excluons les réseaux de neurones car impossible de faire du temps réel en mode apprentissage pour chaque nouveau objet. Par la suite le code fournis sera implémenté sous linux dans un raspberry Pi et servira à un robot de préhension. Uniquement en télétravail. Merci

Bonjour à vous, Nous sommes à la recherche d'un programmeur pouvant nous faire un logiciel Java avec l'API open source OpenCV pour la reconnaissance faciale.
