Fig. 9

Box-and-whiskers plots of the damaged area percentage identified on control rosettes. Each automatic method is assessed under different lighting conditions and on white (top row) and black (lower row) backgrounds. Data are obtained from A. thaliana Col-0, Bla-2 and Kon genotypes, n = 8. Lighting conditions (brightness and contrast for each case): w2 and b2 (central column) = Automatic threshold (30,-20 White; 40,-10 Black); w1, w3, b1 and b3 values are selected for each background subtracting and adding 10 values of brightness, respectively, maintaining contrast values. Black dots indicate outlier values
