Object Detection — NMS Algorithm (Non-Maximum Suppression Algorithm)

1、非极大值抑制算法提出的目的

在目标检测中，为了消除多余的检测框，找到最佳的物体检测的位置。

2、 非极大值抑制（Non-Maximum Suppresion， NMS）

什么是非极大值抑制

Non-maximum suppression technique (NMS), also referred to as non-maximum suppression, is a method designed to suppress elements that are not local maxima. This technique can be understood as a local maximum detection process. A neighborhood is defined by two parameters: dimension and size. Its primary application is in object detection tasks where it identifies the highest-scoring window. For instance, in pedestrian detection, sliding windows are used to extract features, which ar
