VisionEye View Mapping d'objets à l'aide de Ultralytics YOLOv8 🚀

Qu'est-ce que la cartographie d'objets VisionEye ?

Ultralytics YOLOv8 VisionEye permet aux ordinateurs d'identifier et de pointer des objets, en simulant la précision d'observation de l'œil humain. Cette fonctionnalité permet aux ordinateurs de discerner et de se concentrer sur des objets spécifiques, tout comme l'œil humain observe les détails d'un point de vue particulier.
