Improved Wasserstein GAN (WGAN-GP) application on MRI dataset

Application of a deep generative adversarial network on MRI images of knees. The MRI database used was provided by Imperial College London, however similar databases can be found on the OAI website (http://www.oai.ucsf.edu/), an observational study dedicated to monitor the natural evolution of osteoarthritis. The dataset used in this project was comprised of 28800 2D black&white MRI images of size 64x64.

Prerequisites

  • Python, Lasagne (developer version), Theano (developer version), Numpy, Matplotlib, scikit-image
  • NVIDIA GPU (5.0 or above)

Results

The hyperparameters used were:

  • a learning rate of 0.0005
  • a decay rate of 0.5
  • a batch size of 128 images
  • a z space of 200

The network was trained using 35 epochs (~7800 iterations)

  • Examples of real images from the input dataset
