Table 1 Detailed Comparison of CotLeaf-1, CotLeaf-2 and CotLeaf-X Datasets. These three datasets differ in terms of season (Year, Y), growing environment (GH: Glasshouse, FD: Field), leaf number (L3 or L4), planting location, number of genotypes (see Table 2) or populations (A or B) imaged, total number of images, image location (see Fig. 1), presence/absence of multiple images per leaf, hairiness scale, and how hairiness scores were attributed
