Box-and-whiskers plots representing the estimated damaged area (mm2). Data were obtained from each system under different lighting conditions and white and black backgrounds: (a) Without control rosette correction, and (b) after error correction using rosette controls. Data were obtained from A. thaliana Col-0 genotype, infested with 50 T. urticae adults for 4 days; n = 3. Lighting conditions (Brightness, Contrast for each case): A1 = 1,-56; A2 = 50,-25; A6 = 90,-100; A4 = Automatic threshold (30,-69 White; 40,-69 Black); A3 and A5 values were selected for each background subtracting and adding 10 values of brightness, respectively, maintaining contrast values. Black dots indicate outlier values
