Assessment of Weed Classification Using Hyperspectral Reflectance and Optimal Multispectral UAV Imagery

open access: yesAgronomy, 2021
Weeds compete with crops and are hard to differentiate and identify due to their similarities in color, shape, and size. In this study, the weed species present in sorghum (sorghum bicolor (L.) Moench) fields, such as amaranth (Amaranthus macrocarpus ...
