Semantic-Segmentation-with-Sparse-Labels

The labels and codes for Semantic Segmentation of Remote Sensing Images with Sparse Annotations.

Data

We provid three types of sparse annotations: polygon, scribble, and point. <img src="./data_example.png" width = "640" height = "380" alt="example" align=center />

Usage

1. install dependencies in requirements.txt
2. download and unzip data in the folder data. The directory structure should be as follows:

  path/to/data/
    City/  # Vaihingen or Zurich      
      img/        # images
      line/       # line/scribble-level sparse annotations
      point/      # point-level sparse annotations
      polygon/    # polygon-level sparse annotations
      gt/         # dense gt
      eroded_gt/  # dense gt without boundaries
      

3. download and unzip weights in the folder weights.
4. run python train.py and python test.py for testing and training
