Repeated Multiview Imaging for Estimating Seedling Tiller Counts of Wheat Genotypes Using Drones

Table 2

Cross-validation (CV) results for training of beginning of stem elongation support vector machine. Results are root mean squared errors (RMSEs) in growing degree days (GDDs) and relative root mean squared errors (rRMSEs).
