SAR-CNN : SAR image despeckling through convolutional neural networks

This is the implementation in Python/Torch of the paper "SAR image despeckling through convolutional neural networks".Results differ slightly from those of the paper, obtained using Matlab/MatConvNet.

Prerequisits

All the functions and scripts were tested on Python 3.6, PyTorch 0.4.1 and Cuda 9.2, the operation is not guaranteed with other configurations. The command to create the CONDA environment:

conda env create -n env_cnn_nlm -f environment.yml

The command to anctivate the CONDA environment:

conda activate env_cnn_nlm

Please download the datasets using the provided script:

bash download_sets.sh
python generate_noisy_synthetics.py

Usage

Demo

Use demo_sync.py to execute a demo.

Training and Testing

The command to train the network on synthetic data:

CUDA_VISIBLE_DEVICES=0 python experiment_sarcnn17.py --exp_name new_train

The command to test the network on synthetic data:

CUDA_VISIBLE_DEVICES=0 python experiment_sarcnn17.py --eval --eval_epoch 50 --exp_name new_train

NOTE: the SSIM of the paper is little different because it was computed using Matlab instead of Python.
