Modern precision agriculture takes advantage of image data collected from various platforms to monitor crops and optimize their management and maximize yield. Plant productivity is significantly affected by various types of plant stress, such as those due to nitrogen, water, weed, or disease, which can be inferred from monitoring various reflectance indices. However, the classification of plant stress/severity levels especially based on limited data involving multiple stress types remains a major challenge. Similarly, automated plant data acquisition platforms, or even citizen science applications, require the ability to detect and recognize plant species in the wild. Despite a remarkable progress, this is still a challenging problem due to the variety of plant species, the unconstrained imaging conditions, and the variable reproductive state of plants, which also lead to a wide intra-species variability compared to the inter-species separation. This makes it a so-called fine-grained recognition problem (Keaton et al., 2021).
