Dice分割评价指标是用于衡量图像分割结果的一种常用评价指标,其定义如下: Dice分数(Dice Score,也称为Dice系数或F1-Score)是一种衡量分割算法性能的指标,用于比较预测的分割结果与真实标签之间的相似度。它是通过计算分割结果和真实标签的交集与它们的并集之间的比例来计算的。 具体计算公式如下: Dice Score = (2 *...

evaluation with Dice score and Jaccard index on five medical segmentation tasks. Through the application of relative approximation bounds, we show that all surrogates are equivalent up to a multiplicative factor, and that no optimal weighting of cross-entropy exists to approximate Dice or Jaccard ...
