Webpython计算iou（交并比）. 目标检测当中，经常会提到一个词语或者说概念叫iou，全称intersection over union，也就是交并比，指的是相交的的区域面积比上相并的区域面积，简单来讲就是交集除以并集，我们用python代码实现一下. 公式如下：. 变换一下，分母可以用 ... Web24 aug. 2024 · IoU is an important accuracy measure to track when gathering human annotations. The industry best practice is to include a minimum IoU requirement for their human annotation tasks, to ensure that the annotations that are delivered have an IoU >= X (where X = 0.95 is typical) with respect to the “perfect” annotation of that object, as …
