NIR Hyperspectral Imaging for Food and Agricultural Products

Another indicator of the vitahty of this scientific topic is the number of reviews that has flourished over the last years no less than 23 reviews have been pubhshed since 2007 Most deal with hyperspectral (HS) techniques for food and agrofood quality and safety inspection [4-18] and, except for Kim et al. [14], who focus on shortwave NIR and visible, they generally include not only NIR HS vision but also visible, Raman, and fluorescence imaging. Others focus on one type of commodity, such as fruit [19-21], meat [6], hams [22], wine wastes [23], or one specific issue such as fecal and microbial contamination [24]. 

NIR imaging experiments create 3D images two dimensions provide spatial information and one dimension provides spectral information. If the third dimension is restricted to a limited number of wavelength bands (typicaUy between 3 and 10), a multispectral image is created when the whole spectrum is scanned.
