Thanks to Davide we are running the new shining source code versioning system (Git) on Github and managed to have the Sphinx generated documentation platform that builds up very nicely.
See yourself:
http://github.com/alexlib/openpiv-python (source code)
http://alexlib.github.com/openpiv-python (documentation)
Eventually our project is moving full steam ahead. There are couple of great developers joined us that immediately changed the picture.
Python version is now on the right path, thanks to Davide. See our new stuff on Github: http://github.com/gasagna/OpenPiv and also documentation started on http://openpiv.sf.net/python
The C++ version is now also in very good hands. Tim joined us on Sourceforge effort to make C++ readable, extensible and modular. See yourself on http://sf.net/projects/openpiv -> Develop
Everybody is welcome to join the development of C++ and Python. The Matlab version is pretty stable but will not attract much of our attention due to the non-open and non-free policy of Mathworks Inc. Unfortunately, there is no point anymore to support it by developing open source and free tools for all.
Thanks all
Alex
Zach committed the pre-alpha version of C++ with Qt4 new interface for the developers. Use svn to check it out. It compiles well on Mac OS X using Qt qmake and make
It was easier than anything else using the Macports http://www.macports.org/.

We’re glad to solve one of the most annoying features (‘bugs’) of our Matlab version of the OpenPIV software package – the speed. It was very slow. Using >> profile on, urapiv_gui, profile report we identified the most problematic point – the redraw of the QUIVER. The change was then small, quick but very significant. The 1000 x 1000 pixels image is processed within few seconds using standard 32 x 32 interrogation window and simple signal-to-noise algorithm test (peak to mean ratio).
Download the new version https://sourceforge.net/projects/openpiv/files/openpiv/Openpiv_Matlab/openpiv_Matlab_May2010.zip/download and enjoy.
We updated the web site too: http://www.openpiv.net with the new download link.
Please report bugs/feature requests on our http://openpiv.sourceforge.net developers web site and forums.
I need a piv dic open source for my work.
Please, visit http://www.openpiv.net and download any of the open source package: Matlab, Python or C++

They are from mexico and I am currently setting up a laboratory for velocimetry, and I want to implement your program.
you’re welcome to use our OpenPIV. just download any version you like: Matlab (r), Python or C++ (with GUI in Qt)
The direct download link is below:
Of course one could use the website and the link from there:
or using the SVN server to get the /Matlab/trunk
svn co https://openpiv.svn.sourceforge.net/svnroot/openpiv openpiv
The snapshot of the new version looks like the previous ones, but there are few bugs fixed:
a. RGB TIFF images are readable now, using Matlab’s rgb2gray function
b. tiffread2.m file is included for the other TIFF file formats. Thanks to the authors (read inside the license information)

Update from SVN (see the wiki for the instructions) openpiv.wiki.sourceforge.net
Basically it’s a merged /trunk and /branches/Dec2007 versions
New features:
Aeronaut are discussing. 
kheloufi nouredine are discussing. 
Humberto salinas are discussing.

there is one warning message during qmake about missing resources in image.qrc

Is there any work being done on porting it, the python version at least, to linux?
Alex Liberzon 3:25 pm on March 3, 2011 Permalink
python version is mutli-platform. just download the full package from http://www.pythonxy.com or from Enthought. com (the EPD package) and it will work.
C++ version is also multi-platform. In fact it’s developed on Linux, but works great on Windows and on MAC OS X as well.
