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 and Tk graphical user interfaces are in development, to ease the use for those users who don't have python skills.

The OpenPIV python version is still in its 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.

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

Use PyPI: https://pypi.python.org/pypi/OpenPIV:

pip install openpiv

conda install -c conda-forge openpiv

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:

python setup.py install 

The OpenPIV documentation is available on the project web page at http://openpiv.readthedocs.org
