Hyperspectral and multispectral imaging in the food and beverage industries
J Qin, United States Department of Agriculture, USA
Abstract:
This chapter presents hyperspectral and multispectral imaging technologies in the food and agricultural area. It puts emphasis on the introduction and demonstration of spectral imaging techniques for practical uses. The main topics include spectral image acquisition methods, essential components for building spectral imaging systems (e.g., light sources, wavelength dispersive devices and area detectors), methods for calibrating spectral imaging systems (e.g., spectral and spatial calibrations) and techniques for analyzing spectral images (e.g., data preprocessing, dimension reduction and band selection). ...
