EGCTNet: Building Change Detection based on an Edge-Guided Convolutional Neural Network combined with Transformer

(Posted in Remote Sensing)

Here, we provide the pytorch implementation of the paper: Building Change Detection based on an Edge-Guided Convolutional Neural Network combined with Transformer.

For more information, please see our paper at arxiv.

Network Architecture


Quantitative & Qualitative Results on LEVIR-CD and WHU-CD

LEVIR-CD  WHU-CD 

Requirements

Python 3.8.0
pytorch 1.10.1
torchvision 0.11.2
einops  0.3.2

Please see requirements.txt for all the other requirements.

Train on LEVIR-CD

You can run the script file by main_cd.py in the command environment.

Evaluate on LEVIR

You can run the script file by eval_cd.py in the command environment.

Dataset Preparation

Data structure

"""
Change detection data set with pixel-level binary labels；
├─A
├─B
├─label
├─label_edge
└─list
"""

A: images of t1 phase;

B:images of t2 phase;

label: label maps;

label_edge: using the Canny edge detection operator on theusing the Canny edge detection operator on the label maps;

list: contains train.txt, val.txt and test.txt, each file records the image names (XXX.png) in the change detection dataset.
