Table 2 Assessment metrics.
Assessment metrics | Formula |
|---|---|
Precision | \(Precision=\frac{TP}{TP+FP}\) |
Recall | \(Recall=\frac{TP}{TP+FN}\) |
F1-Score | \(F1=\frac{2\times Precision\times Recall}{Precision+Recall}\) |
Overall accuracy | \(OA=\mathop{\sum }\limits_{i=1}^{n}\frac{{x}_{ii}}{N}\) |
IoU | \(IoU=\frac{TP}{TP+FP+FN}\) |
FWIoU | \(FWIoU=\frac{1}{{\sum }_{i=0}^{K}{\sum }_{j=0}^{K}{x}_{ij}}\mathop{\sum }\limits_{i=0}^{K}\frac{{\sum }_{j=0}^{K}{x}_{ij}{x}_{ii}}{{\sum }_{j=0}^{K}{x}_{ij}+{\sum }_{j=0}^{K}{x}_{ji}-{x}_{ii}}\) |
