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 *...

Case 2: generalized_dice_score.aggregate(reduction="sum_batch") returns a single-element tensor but it should return a tensor with the size as number of classes containing dice scores summed across all batches for each class. Similar for mean_batch. Case 3: generalized_dice_score.aggregate(red...
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 ...

Should I calculate the dice score for each image separately and then average them? or do I need to calculate a single dice score over the total "TP", "FP", and "FN" values for all images? Which one is the correct way? 댓글 수: 0 ...

在语义分割任务中，F-score能够提供一个平衡的性能评估，尤其在类别不平衡的情况下，它能够较好地反映模型在不同类别上的整体性能。总之，在深度学习的语义分割任务中，Dice系数和F-score作为评估指标，各有侧重。Dice系数侧重于衡量分割结果的重叠程度，而F-score则综合考虑精确率和召回率，提供一个全面的...
