TODbox (Tiny Object Detection Box)

We have now released the full sets (trainval, test) of AI-TOD-v2! [Download]

This is a repository of the official implementation of the following paper:

[Paper][Code] Detecting tiny Objects in aerial images: A normalized Wasserstein distance and A new benchmark (ISPRS J P & RS, 2022)
[Paper][Code] Dot distance for tiny object detection in aerial images (CVPRW, 2021)

Introduction

The Normalized Wasserstein Distance and the RanKing-based Assigning strategy (NWD-RKA) for tiny object detection. demo image

A comparison between AI-TOD and AI-TOD-v2. demo image

Supported Data

Notes: The images of the AI-TOD-v2 are the same of the AI-TOD. In this stage, we only release the train, val annotations of the AI-TOD-v2, the test annotations will be used to hold further competitions.
