Jupyter Notebooks

train_decoder.ipynb: Construction and training of a neural network optimized for a compressive ratio of 8:1. The network takes compressed data as input and outputs original images.
demo_decoder.ipynb: A guide on using a pre-trained model to reconstruct the original images from their compressed versions.

Files in data/

File formats

• Ground truth data
  • dimension: 512 $×$ 512 (H $\times$ W)
  • format: PNG
  • total number: 19
• Compressed data
  • dimension: 64 $×$ 64 $×$ 8 (H $\times$ W $\times$ C)
  • format: .npy
  • total number: 19

The corresponding compressed data of "000005_10.png" is "000005_10.npy", and the rest files follow the same pattern.
