Shapely intersection over union

Webb25 feb. 2024 · Intersection over Union (IoU) is the most popular evaluation metric used in the object detection benchmarks. However, there is a gap between optimizing the commonly used distance losses for regressing the parameters of a bounding box and maximizing this metric value. The optimal objective for a metric is the metric itself. WebbThe formula for calculating Intersection over Union is called The Jaccard Index. The area of intersection for the two boxes is calculated. Afterwards it is divided by the area of the …
