Accuracy of image analysis tools for functional root traits: A comment on Delory et al. (2017)

Laura Rose; Guillaume Lobet Methods in Ecology and Evolution 2019. doi:10.1111/2041-210x.13156

Other claims from this paper (15)

Method / resource WinRhizo and IJ_Rhizo gave comparable accuracy for diameter and length estimates at 1,200 and 800 dpi.
Method / resource Diameter errors were balanced when estimated against ground-truth values.
Method / resource Volume estimates had a systematic error caused by the assumption of constant diameter.
Observation WinRhizo provides the opportunity to calculate correctly computed volumes from diameter classes.
Observation At 1,200 dpi, IJ_Rhizo failed to find an appropriate threshold, which decreased accuracy.
Association The magnitude of diameter errors increased with root overlap for IJ_Rhizo.
Association Length errors of WinRhizo increased with root length, overlap and root length density.
Association The magnitude of WinRhizo volume underestimation decreased with volume.
Association Volume underestimation was higher for taproot than for fibrous root systems.
Association All errors increased with lower resolution.
Method / resource The results confirm the earlier accuracy results of Delory et al. for length.
Recommendation Estimates from different software packages or resolutions should not be compared directly.
Recommendation Characteristics of root systems should be standardised for image analysis.
Recommendation Methods should be validated for each analysed dataset.
Recommendation New image analysis tools should be validated against a real ground-truth.

Method / resource The model ensemble median underestimated wheat water use in all evaluated environments.
Association Relative underestimation of daily ET was constant across atmospheric evaporative demand levels.
Association Absolute ET error was greater on days of larger evaporative demand.
