wassfast 1.5.5

The next-generation stereo processing pipeline for sea waves 3D reconstruction.

WASSfast is the next-generation stereo processing pipeline for sea waves 3D reconstruction. It exploits the linear dispertion relation and sparse feature triangulation to resolve sea-surface elevation in quasi real-time. At present state, WASSfast can work in two operating modes:

1. Predict-Update (PU) mode. See the paper

2. Convolutional Neural Network (CNN) mode (suggested). See the paper

For the standard pipeline see http://www.dais.unive.it/wass

Note Due to TensorFlow version incompatibilities, WASSfast installed via Pypi supports CNN mode only.

How to use it

Install via pip:

python -m pip install wassfast

and run wassfast --help for a brief description of the command-line options.

Try it with test data

1. Download the test data
2. Extract the test data 7z x wassfast_testdata_256.7z. This will create a directory named wassfast_testdata_256
3. Enter the newly extracted directory: cd wassfast_testdata_256
4. Execute WASSfast:

wassfast ./input ./config256.mat ./config ./settings.cfg RLTB CNN --batchsize 16 -n 49 -r 15.0 -o output.nc 

After the processing, the NetCDF file output.nc is produced. Use Panoply to inspect the reconstructed surface.
