Reinforced Active Learning for Image Segmentation (RALIS)

Code for the paper Reinforced Active Learning for Image Segmentation

Dependencies

  • python 3.6.5
  • numpy 1.14.5
  • scipy 1.1.0
  • Pytorch 0.4.0

Scripts

The folder 'scripts' contains the different bash scripts that could be used to train the same models used in the paper, for both Camvid and Cityscapes datasets.

  • launch_supervised.sh: To train the pretrained segmentation models.
  • launch_baseline.sh: To train the baselines 'random', 'entropy' and 'bald'.
  • launch_train_ralis.sh: To train the 'ralis' model.
  • launch_test_ralis.sh: To test the 'ralis' model.

Datasets

Camvid: https://github.com/alexgkendall/SegNet-Tutorial/tree/master/CamVid

Cityscapes: https://www.cityscapes-dataset.com/

Trained models
