Hyperspectral Machine Vision Enables Smart Automation Mar 20, 2018 — Conventional vision systems often fail to sort items that have similar colors or appearances. In these cases, hyperspectral data combined with spatial pattern recognition algorithms can detect a wide range of materials, patterns, coatings, defects and contaminants. Hyperspectral vision systems generate data for quality control and also transmit information to robotic actuators, enabling automated picking and sorting of commodities. Hyperspectral imaging involves measuring high-resolution
