Flowchart

Introduction

This project concludes the official Pytorch implementation for applying Hopfield layer for deep feature retrieval and aggregration in our paper Dsfer-Net: A Deep Supervision and Feature Retrieval Network for Bitemporal Change Detection Using Modern Hopfield Network which has been conducted at the Institute of Advanced Research in Artificial Intelligence (IARAI).

Preliminaries

s1.11.0+cu113
numpy==1.23.0
einops==0.4.1
scikit-image==0.18.0
scikit-learn==0.24.1

Three datasets are used in this repo: LEVIR-CD dataset, WHU-CD dataset, and CDD dataset.

Detailed settings of the datasets can be found in our paper, and the cropped image can also be downloaded from:

** LEVIR-CD: Google Drive

** WHU-CD: Google Drive

** CDD-CD: Google Drive

The path of the images is orgarnied as follow:

├─ <Root-path-of-the LEVIR-CD and CDD dataset>/
│   ├──train/
│   │  ├──A
│   │  ├──B
│   │  ├──label
│   ├──val/
│   │  ├──A
│   │  ├──B
│   │  ├──label
│   ├──test/
│   │  ├──A
│   │  ├──B
│   │  ├──label
├─ <Root-path-of-the WHU dataset>/
│───A
│───B
│───label

Usage

--dataID                    dataset id in the training/testing.
--data_dir                  root directory of the datasets.
--batch_size                number of images in each batch.
--lam                       the pernatly scalar on loss.
--learning_rate             learning rate.
--weight_decay              regularisation parameter for L2-loss.
--num_steps                 number of training steps.
--num_steps_stop            number of training steps for early stopping.
