Hyperspectral imaging (HS) of tomato leaves inoculated with Alternaria protenta

The dataset consists of hyperspectral images (HS) and associated data of tomato leaves captured during a disease development study. Number of trials took place in an experimental greenhouse where tomatoes of cultivar <i>Encore</i> were inoculated with <i>Alternaria protenta</i> pathogens, and the development of the disease on leaves was captured on a regular basis using an HS camera over the course of several weeks. Additional data were obtained via basic image preprocessing and feature extraction procedures. The dataset is suitable for in-depth disease development studies based both on statistical approaches (e.g. spectral index calculations) as well as deep learning models (e.g., semantic segmentation).
