[SPRS J P & RS 2022] small target detection module: a normalized Gaussian Wasserstein distance for tiny object detection

A Normalized Gaussian Wasserstein Distance for Tiny Object Detection

The author puts forward a new method to measure the distance between frames , Used to solve traditional IoU Measuring problems that are too sensitive to small targets , It can be directly used in anchor frame based detectors and NMS in .

After training on the data collected by myself, I found that this method is really easy to use .

Abstract ：

Detecting small objects is a very challenging problem , The author's key observation is , be based on IoU And its extended cross index for small objects
