Table 3 Calculation equation of evaluation index
From: Cotton stubble detection based on wavelet decomposition and texture features
Index | Equation |
|---|---|
Accuracy | \(Ac = \frac{TP + TN}{{TP + TN + FP + FN}}\) |
Sensitivity | \(Se = \frac{TP}{{TP + FN}}\) |
Specificity | \(Sp = \frac{TN}{{TN + FP}}\) |
