一些评价指标

以下是气道分割领域常用的评价指标

Dice Similarity Coefficient
\[ \mathsf{DSC} = \frac{2TP}{FP+FN+2TP} \]
Precision
\[ \mathsf{Pre} = \frac{TP}{TP+FP} \]
Sensitive
\[ \mathsf{Sen} = \frac{TP}{TP+FN} \]
Specificity
\[ \mathsf{Spe} = \frac{TN}{TN+FP} \]
Tree Length Detected Rate

正确检测到的气道长度与真实气道长度(ground truth)的比值
\[ \mathsf{TD} = \frac{T_{det}}{T_{ref}} \]
Branch Detected Rate

正确检测到的分支数目与真实分支数目的比值
\[ \mathsf{BD} = \frac{B_{det}}{B_{ref}} \]
