Accelerating Atmospheric Turbulence Simulation via Learned Phase-to-Space Transform
This repository contains the code for the following paper:
Zhiyuan Mao, Nicholas Chimitt, and Stanley H. Chan, ‘‘Accelerating Atmospheric Turbulence Simulation via Learned Phase-to-Space Transform’’, accepted to ICCV 2021
Arxiv: https://arxiv.org/abs/2107.11627
How to use:
-
Check the demo.py file
-
The generation of correlation matrix for point spread functions is slow. You can download the correlation matrices prepared by us and put them under the data folder. The correlation matrices are available at:

The code with simulator_old.py is tested with the following environment:
- Python 3.6
- Pytorch 1.4.0
- Numpy 1.19.2
- Scipy 1.6.0
- Matplotlib 3.3.6
Update: we modify the code to work with pytorch 1.10 and beyond. Please use the latest simulator.py. Nothing else has changed. For pytorch 1.4, use simulator_old.py. The difference is due to the pytorch's update on the fft module.
