Prerequisites

The original code is in python 3.6 under the following dependencies:

  1. torch (1.7.0+cu101)(1.9.0+cu111)
  2. torchvision (0.8.0+cu101)(0.10.0+cu111)
  3. tensorlayer (1.7.2)
  4. easydict (1.9)
  5. scikit-image (0.17.2)
  6. tensorboard (2.2.2)
  7. tensorboardX (2.1)
  8. opencv-python (v4.4.0.46)

The Code tested in Windows10 with Nvidia GPU + CUDA(10.1) CuDNN (v7.6.0.64)

How to use

  1. Prepare data

    1. PUT testing.pickle training.pickle validation.pickle into data/MICCAI13_SegChallenge/

  2. Train model

    1. run 'CUDA_VISIBLE_DEVICES=0 python train.py --model MODEL --mask MASK --maskperc MASKPERC' where you should specify MODEL, MASK, MASKPERC respectively:
      • MODEL: choose from 'unet' or 'unet_refine'
      • MASK: choose from 'gaussian1d', 'gaussian2d', 'poisson2d'
      • MASKPERC: choose from '10', '20', '30', '40', '50' (percentage of mask)

  3. Test trained model

    1. run 'CUDA_VISIBLE_DEVICES=0 python test.py --model MODEL --mask MASK --maskperc MASKPERC' where you should specify MODEL, MASK, MASKPERC respectively (as above).
