Adjusted Version (Python3)

The command to run PNN_testing.py with gpu is:

THEANO_FLAGS=device=cuda0 python3 PNN_testing.py -g -s <SENSOR>

pansharpening-cnn

Target-adaptive CNN-based pansharpening is an advanced version of pansharpening method PNN with residual learning, different loss and a target-adaptive phase.

Prerequisits

This code is written for Python2.7 and uses Theano library. The list of all requirements is in requirements.txt.

The command to install the requirements is:

cat requirements.txt | xargs -n 1 -L 1 pip2 install

Optional requirements for using gpu:

cuda = 8
cudnn = 5

Usage

set all paramaters in config_testing_<SENSOR>.xml:
- sensor: GeoEye1, IKONOS, WV2
- mode: full to high resolution pansharpening (PAN scale); reduce to low resolution pansharening (MS scale).
- fine tuning: set epochs 0 to not fine tune; set epochs n to do n epochs of fine tuning.
- paths: path of pretrained network; path of image to test; path of output image; path of fine tuned network.
run test without gpu:

python PNN_testing.py -s <SENSOR>

run test with gpu:

PATH=<CUDAPATH>:$PATH python PNN_testing.py -g -s <SENSOR>

Output:
- result: ./outputs/<SENSOR>/output.mat;
- (eventual) fine-tuned network: ./outputs/<SENSOR>/FT_network/PNN_model.mat.
