Determination of nitrogen and chlorophyll levels in bean-plant leaves by using spectral vegetation bands and indices Discriminação de teores de nitrogênio e clorofila foliares do feijoeiro por meio de bandas e índices de vegetação espectrais

This study aimed to develop classifiers based on different combinations of spectral bands and vegetation indices from original, segmented and reflectance images in order to determine the levels of leaf nitrogen and chlorophyll in the bean, and to define the best time and best variables. A remote-sen...
