GitHub - solvusglobal/openpiv-python: OpenPIV is an open source Particle Image Velocimetry analysis software written in Python, Matlab and C++

Build Status Build status DOI

OpenPIV consists in a Python and Cython modules for scripting and executing the analysis of a set of PIV image pairs. In addition, a Qt graphical user interface is in development, to ease the use for those users who don't have python skills.

Warning

The OpenPIV python version is still in beta state. This means that it still might have some bugs and the API may change. However testing and contributing is very welcome, especially if you can contribute with new algorithms and features.

Development is currently done on a Linux/Mac OSX environment, but as soon as possible Windows will be tested. If you have access to one of these platforms please test the code.

Test it without installation

Click the link - thanks to BinderHub, Jupyter and Conda you can now get it in your browser with zero installation: Binder

Installing

You can use Conda http://conda.io:

conda install -c conda-forge openpiv

We are listed on PyPI: https://pypi.python.org/pypi/OpenPIV, so you could just try:

or

Note that if dependicies of Numpy, Scipy and Cython are not present, on Ubuntu Linux, install those as:

sudo apt-get install cython python-numpy python-scipy
pip2.7 install OpenPIV

GPU Support

If you have a CUDA enabled NVIDIA GPU in your system, you can run GPU accelerated PIV functions. You will need to install PyCuda and scikit-cuda

pip install pycuda
pip install scikit-cuda

To build from source

Download the package from the Github: https://github.com/OpenPIV/openpiv-python/archive/master.zip or clone using git

git clone https://github.com/OpenPIV/openpiv-python.git

Using distutils create a local (in the same directory) compilation of the Cython files:

python setup.py build_ext --inplace

Or for the global installation, use:
