Hyperspectral imaging steps. A calibrated reflectance image (a) is used to reconstruct a RGB-image (b) for manual annotation. The reflectance image (a) is segmented into its main components (c) and vines are labeled based on their GPS position (d). The disease detection model is then applied to the pixels associated with the GPS vine position and the detection ratio is calculated (e)
