Abstract

Crop/weed/soil discrimination by optical reflectance on brassicas proved to be reliable for recognizing leaves of crops from leaves of weeds and soil, although differences on crop varieties, weed species population and type of soil. Radiometers using 10 nm bandwidth filters were used in earlier experiments, but higher reflected radiance could only be collected with the use of broader filtering. The discrimination integration index (DII), presented in this paper, is a broadband discriminator which allows us to study the effect of broader spectral bands on corp/weed/soil discrimination. Some results on cabbage/weed-soil discrimination using DII's for several wavebands are presented.
