英文摘要: Abstract(#br)Hyperspectral images integrate spatial and spectral details together. They can provide valuable information about both external physical and internal chemical characteristics of agricultural and food products rapidly and non-destructively. Despite rapid improvements in instruments and acquisition techniques, the collected high-quality hyperspectral images still contain much useless information, like uneven illumination, background, specular reflection, and bad pixels that need to be removed. That is, hyperspectral image preprocessing is necessary for almost each hyperspectral image to get pure images or pixels, or to reduce negative influences on the subsequent detection, classification, and prediction analysis. This manuscript will enumerate some possible solutions to deal...
