Table 1
Pixel distribution for each testing dataset of the two-class and three-class segmentation models. Mean pixel class share of the N images with standard deviation for each testing dataset of the two-class and three-class segmentation models. Mono: monocrop, Int: intercropping systems without buckwheat, InterBw: intercropping systems with buckwheat, N: number of images per subset, OSR stage: oilseed rape growth stage based on the BBCH scale (Lancashire et al., 1991).
