  • Comparing RGB-based vegetation indices with NDVI for agricultural drone imagery

    Abstract Agribotix conducted a post hoc test of two vegetation indices, VARI and TGI, that used only the three visible-band signals from an unmodified CMOS camera. The results were compared to NDVI, which is generally considered to be a reliable measure of field health and the underlying RGB image. While the results are somewhat encouraging in limited cases, it is clear that neither VARI nor ...
