Metrics | Formula |
|---|---|
IoU | \({\text{IoU = }}\frac{{\left| {{\text{P}} \cap {\text{G}}} \right|}}{{\left| {{\text{P}} \cup {\text{G}}} \right|}}\) |
DSC | \({\text{DSC}} = \frac{{2\left| {{\text{P}} \cap {\text{G}}} \right|}}{{\left| {\text{P}} \right| + \left| {\text{G}} \right|}}\) |
PGA | \(\overline{{{\text{Var}}}} = \frac{{{\text{No}}{\text{.}}\:{\text{of}}\:{\text{hits}}}}{{{\text{Total}}\:{\text{samples}}}} \times 100\) |
ELS | \({\text{SD}} = \frac{{\sum\nolimits_{{i \in G}} {{\text{GRADCAM}}_{i} } }}{{\sum\nolimits_{{i \in I}} {{\text{GRADCAM}}_{i} } }} \times 100\) |
