Detectors often fire several boxes on one object. Non-max suppression (NMS) keeps the highest-confidence box and discards others that overlap it beyond an IoU threshold. Newer detectors aim to be NMS-free to save this post-processing step.
Definition
A cleanup step that removes duplicate overlapping boxes for the same object, keeping only the most confident one. Standard in detection pipelines.
