“HCGMNET: A HIERARCHICAL CHANGE GUIDING MAP NETWORK FOR CHANGE DETECTION, IGARSS 2023， Oral, Chengxi Han, Chen Wu, Bo Du, 😋😋😋

[2 Sep. 2023] Release the first version of the HCGMNet

Requirement

-Pytorch 1.8.0  
-torchvision 0.9.0  
-python 3.8  
-opencv-python  4.5.3.56  
-tensorboardx 2.4  
-Cuda 11.3.1  
-Cudnn 11.3  

Training, Test and Visualization Process

python train_HCGMNet.py --epoch 50 --batchsize 8 --gpu_id '1' --data_name 'WHU' --model_name 'HCGMNet'   #HCGMNet

python test.py --gpu_id '1' --data_name 'WHU' --model_name 'HCGMNet'

You can change data_name for different datasets like "LEVIR", "WHU", "SYSU", "S2Looking", "CDD", and "DSIFN".

Test our trained model result

You can directly test our model by our provided HCGMNet weights in output/WHU, LEVIR, SYSU, S2Looking, CDD, and DSIFN . Download in Baidu Disk,pwd:2023 😋😋😋

And also we provide all test results of our CGNet in the HCGMNetTestResult!!!! Download in HCGMNetTestResult or Baidu Disk,pwd:2023 😋😋😋

Dataset Path Setting

 LEVIR-CD or WHU-CD 
     |—train  
          |   |—A  
          |   |—B  
          |   |—label  
     |—val  
          |   |—A  
          |   |—B  
          |   |—label  
     |—test  
          |   |—A  
          |   |—B  
          |   |—label

Where A contains images of the first temporal image, B contains images of the second temporal image, and label contains ground truth maps.
