Felix Kronenwett

Scientific employee at Fraunhofer IOSB

Specialized in signal processing, machine learning, computer vision, and hyperspectral imaging. I am currently a research associate at Fraunhofer IOSB in Karlsruhe in the Visual Inspection Systems (SPR) department working in the field of sensor-based sorting systems. My interests include probabilistic machine learning, deep learning based computer vision, real-time capable systems, and creating sustainable solutions for recycling and agriculture. Through my research, I strive to advance innovative sensor technologies and data-driven approaches for efficient industrial applications.
