Figures
There are errors in Figs 9–12. In Figs 9 and 10, the images and captions have been switched. In Figs 11 and 12, the images only have been switched. Please view the correct Figs 9–12 and their captions here. The publisher apologizes for the errors.
(a) the entire root section analysed. The magenta rectangle in the bottom image denotes a small piece of segregated root that the algorithm has failed to capture. (b) zoomed versions of the respective stele regions highlighting cortical cells (red), epidermal cells (orange), stele cells (blue) and central metaxylems (green).
(a) The original image. (b) Results from RootScan. (c) Results of RootAnalyzer.
The two images depict damaged root cross-sections with missing or displaced epidermis and cortex regions. The damaged sections are major factors contributing to the relatively large errors in cortex (and presumably epidermis) cell calculations.
13 of the 15 images produce a much lower degree of error in average cortex cell area calculation. The two red markers of significant error correspond to poor quality (i.e., damaged) root images.
