**TLDR:** An operation that filters overlapping boxes produced for the same object in order to create cleaner detection output.

<p>Non-Maximum Suppression is a critical post-processing step that makes raw object detection output usable. Detection models often generate multiple similar boxes for the same object, and NMS keeps the most confident one. If the threshold is too aggressive, objects may be lost; if too loose, duplicates remain. It is therefore one of the key quality control points in a detection system.</p>
