Web9 mrt. 2024 · GIOU具有4个特点： 1、与IOU相似，也是一种距离度量，作为损失函数满足损失函数的需求 2、GIOU对scale不敏感 3、GIOU是IOU的下界，取值为 [-1, 1]，在两个框无重合的情况下，IOU=0，减数为1，GIOU即为-1，当两个框完全重叠，IOU=1，减数为0，则GIOU=1（可以理解为由于惩罚项的引入，在不重叠的情况下，预测框会向目标框移动） … Web本文的IoU-Net网络提出了PrRoI Pooling(Precise RoI Pooling)，通过IoU-Net网络得到预测的IoU值(又称之为定位置信度，下面的定位得分、Loc Conf都是同一个意思)。这个预测的IoU值可以用来改进NMS算法(作者改进的算法称之为IoU-Guided NMS)及Bounding Box Regression方式(作者将改进的算法称之为Optimization-based方式)。二、Motivation 改 …
