IMAGING FEATURES
Hyperspectral and Multispectral Imaging Mar 3, 2020 — Over the past two decades, hyperspectral imaging and multispectral imaging have been growing in prominence and utility. Although the terms are often conflated, they represent two distinct imaging practices, each fitting its own application spaces. Both technologies present advantages over standard machine vision imaging, which uses light only from the visible spectrum. However, with the benefits of HSI and MSI comes increased complexity of the imaging systems in terms of lighting, filtering,...
