One-Class Risk Estimation for One-Class Hyperspectral Image Classification

by Hengwei Zhao, Yanfei Zhong, and Xinyu Wang

[Paper(ISPRS)] [Paper(TGRS)]

---

This is an official implementation of absNegative and One-class Risk Estimation in our ISPRS 2022 paper and TGRS 2023 paper, respectively.

Applications:

1. Invasive tree species detection from airborne hyperspectral images [ISPRS (2022)]
2. Pest and disease detection from UAV-borne hyperspectral images [JAG (2022)]
3. Crop extraction from spaceborne hyperspectral images [JAG (2021)]

Requirements:

• pytorch >= 1.13.1
• GDAL ==3.4.1

Running

1.Modify the data path in the configuration file (./configs/config_XX.py). The hyperspectral data can be obtained from the Link(password:sqyy)

2.Training and testing

sh sh/LongKou.sh
