The multiclass confusion matrices of best classification results achieved for different hyperspectral imaging techniques for detecting mycotoxin contamination in ground maize using SVM model. (a) Fluorescence with SNV, (b) VNIR with range normalization, and (c) SWIR with SG2. Below cut-off: aflatoxin contents below 10 μg/kg and fumonisin contents below 1 mg/kg, AF: aflatoxin contamination, FM: fumonisin contamination, Co-con: both aflatoxin and fumonisin contamination.
