英文摘要: Salmonella is a leading cause of foodborne illness. Traditional detection methodsrequire lengthy incubation periods or expensive reagent kits. Hyperspectral microscope images (HMIs) have beenpreviously investigated as a method for early and rapid detection of bacteria by using a spectral signature thatis unique to the organism. Previous HMI use with bacteria has consisted of supervised classification withhypercubes collected for single culture images isolated from highly selective growth media. In order to moveforward with HMI as a detection tool in the food industry, unsupervised classification of bacteria cells in mixedculture HMIs was investigated. Four foodborne bacteria cultures, S. Typhimurium (ST) E.coli (Ec), S. aureus (Sa) and L. innocua (Li) were combined in seven...
