Code for FastVSDF: An Efficient Spatiotemporal Data Fusion Method for Seamless Data Cube

Overview

FastVSDF is an efficient spatiotemporal data fusion method.

The purpose of proposing FastVSDF is to achieve data fusion at the lowest cost. Therefore, FastVSDF requires only minimal input data, while the computational cost needed is low.

It takes a fine/coarse image pair at T1 and coarse image at T2 to predict fine image at T2: image

Get Started

Prepare Environment [Python>=3.6]

  1. Download source code from GitHub. 
    git clone https://github.com/ChenXuAxel/FastVSDF

cd FastVSDF && git checkout release
  2. Install dependencies. 
    conda install gdal guided_filter_pytorch scikit-learn scikit-image pytorch

Predict

from FastVSDF import FastVSDF
FastVSDF(F1_path, C1_path, C2_path, fastvsdf_path)
