This is an official implementation of STAR and ChangeStar in our ICCV 2021 paper Change is Everywhere: Single-Temporal Supervised Object Change Detection for High Spatial Resolution Remote Sensing Imagery.

We hope that STAR will serve as a solid baseline and help ease future research in weakly-supervised object change detection.

Features

Getting Started

Install EVer

pip install ever-beta==0.2.3

Requirements:

Prepare Dataset

  1. Download xView2 dataset (training set and tier3 set) and LEVIR-CD dataset.

  2. Create soft link

ln -s </path/to/xView2> ./xview2
ln -s </path/to/LEVIR-CD> ./LEVIR-CD

Training and Evaluation under Single-Temporal Supervision

bash ./scripts/trainxView2/r50_farseg_changemixin_symmetry.sh

Training and Evaluation under Bitemporal Supervision

bash ./scripts/bisup_levircd/r50_farseg_changemixin.sh
