Introduction

This repository contains the weakly supervised learning framwork for domain adaptation of built-up regions segmnentation based on the work described in ISPRS Photogrametery and Remote Sensing 2020 paper "[WAN: Weakly-Supervised Domain Adaptation for Built-up Region Segmentation in Aerial and Satellite Imagery]". (https://arxiv.org/pdf/2007.02277.pdf).

Requirements:

The code is tested in Ubuntu 16.04. It is implemented based on Keras with tensorflow backend and Python 3.5. For GPU usage, the maximum GPU memory consumption is about 7 GB in a single GTX 1080.

Setup

We assume you are working in wan-master folder.

0. Datasets:

• Download Rwanda dataset.
• Put downloaded data in "datasets" folder.

Usage

0. Set the PYTHONPATH environment variable:

cd wan-master

1. Adaptation

• OSA: Output space Adaptation:

python adapt_OSA.py --data-dir path_to_dataset_folder --data-list-train training_images_list --data-list-val validation_images_list

• LTA: Output space Adaptation:

python adapt_LTA.py --data-dir path_to_dataset_folder --data-list-train training_images_list --data-list-val validation_images_list

• To run the code, you need to set the data paths of source data (data-root) and target data (data-root-tgt) by yourself. Besides that, you can keep other argument setting as default.

4. Evaluation

5. Train in source domain

python train.py --data-dir path_to_dataset_folder --data-list-train training_images_list --data-list-val validation_images_list
