Lossy Image Compression with Compressive Autoencoders

See wiki for more details and further results.

Results

cae_32x32x32_zero_pad_bin model, after roughly 5.8 millions of optimization steps; left: original, right: reconstructed.

Resources

A smaller dataset (2,286 frames) that I have used in the Further results page of the wiki can be downloaded here.

A bigger dataset can be constructed by downloading frames using the scripts provided here. For the above results, I have randomly selected and downloaded 121,827 frames.

Environments

  • GTX 1080 Ti (with 11GB graphic memory)
  • Ubuntu 16.04
  • Python 3.5
  • Cuda 9.0
  • Pytorch 0.4.1

Training

python3 train.py --exp_name Kodak --shuffle --dataset ./dataset/Kodak

Testing

python3 test.py --chkpt ./checkpoints/Kodak/model_final.state --shuffle --dataset_path ./dataset/Kodak --out_dir ./Kodak
