Implementation of the methods described in the paper entitled “Multi-task deep learning for satellite image pansharpening and segmentation”

Multi-task Framework Architecture

Framework

Software Architecture

Software Architecture

Dependencies

  • Python 3.6.4
  • Tensorflow 1.10.0
  • Numpy 1.14.2
  • GDAL 2.2.4
    The codes have been tested on Fedora 25

Visualization (Optional)

We recommend to use QGIS, where the outputs can easily be displayed despite of the image size.

Usage

  • The solver sub-directories, namely training_solvers and test_solvers contain solvers, which train a model and test the trained model (See the figure under Software Architecture section).
  • To train a model, enter the following command (we assume that you are under multi-task directory, otherwise you will get an error): python3 train_solvers/train_solver<id>.py
  • To test a trained model, enter this command: python3 test_solvers/test_solver<id>.py

<id> in the commands above determines which solver to run.

Example Visual Results From the World-View3 Dataset

Here, we illustrate several original visual outputs from the World-View3 dataset for different methods including our multi-task framework.
