A Corrigendum on
Peanut Leaf Wilting Estimation From RGB Color Indices and Logistic Models

by Sarkar, S., Ramsey, A. F., Cazenave, A.-B., and Balota, M. (2021). Front. Plant Sci. 12:658621. doi: 10.3389/fpls.2021.658621

In the original article, there was a mistake in Table 5 as published. There were typos in the text and numbers of the table. The corrected Table 5 appears below:

TABLE 5

Table 5. Wilting accuracy matrix with the number of manually taken wilting scores (2018) on a visual scale at the left and outside the table and the count of image-derived wilting scores in the table.

In the original article, there was an error. There were typos in the equations of Model 1.

A correction has been made to Results, Ordinal Logistic Models to Estimate Wilting (Ordinal 0-5 Rating), paragraph 3, Model 1 equations:

Model 1 for proximal RGB images:

$\begin{array}{l}{P}_0=\frac{e^{({\epsilon }_a-11.75)}}{1+e^{({\epsilon }_a-11.75)}}\end{array}$

$\begin{array}{l}{P}_1=\frac{e^{({\epsilon }_a-7.19)}}{1+e^{({\epsilon }_a-7.19)}}-P_0\end{array}$

$\begin{array}{l}{P}_2=\frac{e^{({\epsilon }_a-4.28)}}{1+e^{({\epsilon }_a-4.28)}}-P_0-P_1\end{array}$

$\begin{array}{l}{P}_3=1-P_0-P_1-P_2\end{array}$

In the original article, there was a mistake in Table 9 as published. There were typos in the numbers of the table. The corrected Table 9 appears below.

TABLE 9

Table 9. Wilting accuracy matrix with the number of manual wilting scores (2019) on a visual scale at the left and outside the table and the count of image-derived wilting scores in the table.

The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
