Iouloss giouloss
Webgiou loss计算公式 Giouloss是一种广泛用于目标检测和计算机视觉领域中的损失函数,它可以度量两个目标之间的相似度和重叠程度。 Giou loss是在IoU loss的基础上发展而来,它在计算目标重叠度时,考虑了目标之间的最小闭合区域。 Giou loss的计算公式如下: $Giou = IoU - frac { (C - U)} {C}$ 其中,IoU指的是两个目标的交集面积除以它们的并集面积,C是 … Web一是认为ciou loss对于长宽比的加入loss的设计不太合理,于是将ciou loss中反应长宽比一致性的部分替换成了分别对于长和宽的一致性loss,形成了eiou loss(从后面公式可以看 …
