使用图像分割,绕不开Dice损失,这个就好比在目标检测中绕不开IoU一样。 1 概述 Dice损失和Dice系数(Dice coefficient)是同一个东西,他们的关系是: DiceLoss=1−DiceCoefficientDiceLoss=1−DiceCoefficient 1.2 Dice 定义 Dice系数, 根据 Lee Raymond Dice命名,是一种集合相似度度量函数,通常用于计算两个样本的相...

The Dice similarity coefficient of two setsAandBis expressed as: dice(A,B) = 2 * |intersection(A,B) | / ( |A| + |B| ) where |A| represents the cardinal of setA. The Dice index can also be expressed in terms of true positives (TP), false positives (FP) and false negatives (...

similarity = generalizedDice(X,target) calculates the generalized Sørensen-Dice similarity coefficient between test image X and target image target. example similarity = generalizedDice(X,target,'DataFormat',dataFormat) also specifies the dimension labels, dataFormat, of unformatted image data. You ...
