[TGRS 2023] When Vectorization Meets Change Detection

CVNet

This is Pytorch implementation for "When Vectorization Meets Change Detection". If you have any questions, please contact [email protected]

Overview

The overall framework for CVNet.

Installation

Ubuntu-18.04, CUDA 11.0, pytorch1.7/1.8, GCC 7.3

conda create -n cvnet python=3.7
conda activate cvnet
conda install pytorch==1.7.0 torchvision==0.8.0 cudatoolkit=11.0 -c pytorch

cd cvnet
conda develop .
pip install -r requirements.txt

For evaluation with boundary IoU, please install boundary IoU API following the installation instruction.

Training & Testing

Data prepare

• The datasets can be downloaded from:
• WHU-Vector-CD: https://pan.baidu.com/s/1j1hu1gI4yWHQHNWobwQEYA code：ikls
• LEVIR-Vector-CD: https://pan.baidu.com/s/13loTooaG0hK5zukgVe1sVw code：ikls

Please put the change vectorization datasets into datasets folder. The datasets folder is constructed as follows:

code_root/
└── data/
    └── WHU_VectorCD/
        ├── train/
            ├── A
            ├── B
            └── annotation.json
        └── val/
            ├── A
            ├── B
            └── annotation.json
    └── LEVIR_VectorCD/
        ├── train/
            ├── A
            ├── B
            └── annotation.json
        └── val/
            ├── A
            ├── B
            └── annotation.json

Training

The model with HRNetV2 as backbone are initialized with imagenet pretrained parameters. You could download them from https://github.com/HRNet/HRNet-Image-Classification and put them in the path of ./CVNet/backbones/hrnet_imagenet.

bash train.sh
bash unite_train.sh

Testing

bash test.sh

Evaluation

We provide implementation of different metrics for evaluation. You can run the following command to evaluate the test results in MS-COCO format.

python tools/evaluation.py --gt-file [GT_ANNOTATION_FILE] --dt-file [PREDICT_ANNOTATION_FILE] --eval-type boundary_iou

cvnet's Issues

annotation.json文件怎么生成的？

您好，我对您出色的工作非常感兴趣，但是我缺少了annotation.json文件，这个是怎么生成的呀，有具体的代码嘛
