[arXiv] [Paper(ICCV 2023)]

This is an official implementation of T-HOneCls in our ICCV 2023 paper.

Highlights:

Class prior-free PU learning for limited labeled hyperspectral imagery
T-HOneCls achieves state-of-the-art results on 7 datasets (21 tasks in total)

Requirements:

pytorch >= 1.13.1
GDAL ==3.4.1

Running

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

2.Training and testing

sh scripts/HongHu.sh
sh scripts/LongKou.sh
sh scripts/HanChuan.sh
