Webpression (NMS). The widely used classical approach is a greedy heuristic. Detections are sorted by their scores in a decreasing order. Then each detection is checked against all following in the sorted list. If the Intersection over Union (IoU) with one of the following detections is larger than a certain threshold the latter detection is removed.
