Fig. 2.

Raw and processed photographs (A–K) and scans (L) of Solanum lycopersicum (A, B, C), Triticum aestivum (D, E), Dendromecon harfordii (F, G), Sequoia sempervirens (H), Ribes malvaceum (I), Pinus jeffreyi (J), and Quercus lobata (K, L). Images after Arabidopsis-based automated processing (B, F), and images after user-calibrated automated processing (C, E, G–K). Areas recolored green were identified as leaves and areas recolored red were identified as calibration area. Darker nongreen components in C and E fit pixel threshold and color ratio criteria, but were below the minimum component size, and so were not included in leaf area or canopy cover calculations. Minimum component size analysis was not used in F–L.
