Exemplary images and confusion matrices for (a) species (b) and species and life cycle stage of four different classifiers trained on (1) brightfield images alone, (2) Chl a fluorescence images alone, (3) all brightfield—Chl a fluorescence images (“All images”) and (4) merged brightfield-Chl a fluorescence images (“Merged images”) solely identifying species and identifying species at different life cycle stages. The scale of the confusion matrices indicates the percentage of correct and incorrect classifications
