Introduction

This repo is the official implementation of our paper: Extraction of cropland field parcels with High-Resolution Remote Sensing Images using multi-task learning. The prediction process is shown in figure below.

How to use

1. To obtain the cropland parcel(without using patch refinement)

   python main.py --img ${image_path} --weights ${weights_path} --shp ${the_path_of_output_in_shapefile}

2. The next step is repair the break line

   python PatchRefinement.py --lineDN ${lineDN_path} --img ${image_path} --weights ${weights_path}

   PS:The training code can be found here.

3. In final, merge the results of the two steps.

   python postprocess.py --img ${image_path} --shp ${the_path_of_output_in_shapefile}

Training code

The code works a bit cluttered and without comments, download it if you need. link：https://pan.baidu.com/s/1AKwMW9-0t8MA6LoEzgt6VA?pwd=kqau pwd：kqau
