在医学图像分割领域,Dice系数(Dice Similarity Coefficient,DSC)是评估算法分割结果与医生标注真实区域重合度的核心指标。其公式为: $$ DSC = \frac{2|X \cap Y|}{|X| + |Y|} $$ 其中,( X )代表算法预测的病灶区域,( Y )代表人工标注的真实区域。Dice系数越接近1...
1. DSC（Dice Similarity Coefficient）：又称Sørensen-Dice系数，是由Lee RaymondDice在1945年提出的，用于衡量两个集合的相似度。在图像分割领域，DSC被广泛用于评价分割结果与真实标注之间的匹配程度。2. Dice系数：实际上，DSC和Dice系数是同一个概念，只是在某些文献中可能会有不同的称呼。为了保持一致性，本文...

dice系数(dice similarity coefficient)和IOU(intersection over union)都是分割网络中最常用的评价指标。传统的分割任务中,IOU是一个很重要的评价指标,而目前在三维医学图像分割领域,大部分的paper和项目都采用dice系数这个指标来评价模型优劣。那么二者有什么区别和联系呢?

Dice similarity coefficient, returned as a numeric scalar or numeric vector with values in the range [0, 1]. A similarity of 1 means that the segmentations in the two images are a perfect match. If the input arrays are: binary images, similarity is a scalar. label images, similarity is...
