Problem with commonly used l1 or l2 loss for object detection the minimization of loss does not directly correlates with IoU gain.

However, IoU has a plateau making it infeasible to optimize in the case of non-overlapping bounding boxes. In this paper, we address the this weakness by introducing a generalized version of IoU as both a new loss and a new metric.

WebOct 27, 2024 · Intersection over Union(IoU) is defined as ratio between Area of intersection and Area of Union from two boxes. In the field of horizontal object detection, researchers found that computing the IoU loss using the IoU between the predicted and target boxes is better than using the L1-loss directly at training time.
