File Information
Description

PTVlab (Particle Tracking Velocimetry - lab) is a Matlab software featuring state of the art mathematical algorithms and a Graphical User Interface (GUI) adapted from the open source project PIVlab.

This software aims at the analysis of experimental Image Velocimetry measurements using a Lagrangian frame of reference, which can offer several benefits compared to the standard Particle Image Velocimetry (PIV) technique. Several institutions have been involved in the development of PTVlab. Dr Wernher Brevis mainly developed the underlying mathematical algorithms and their implementation during his PhD studies at the University of Chile, Chile and Karlsruhe Institute of Technology, Germany (Brevis et al, 2011). Dr Brevis's research groups at the University of Sheffield, United Kingdom, have developed new algorithms and bug fix. The adaptation of the graphical user interface of PIVlab and the development of new functionalities have been contributed by Antoine Patalano, as part of his PhD studies at the National University of Cordoba, Argentina. Our intention is to contribute with an open source, state of the art and easy to use tool for the analysis of experimental fluid mechanics images, thus we are releasing a Beta version of the software for testing. There are still several bugs that need attention but the main functionalities have been tested and validated.

Feel free to ask any questions regarding the implemented functionalities. Any feedback, including improvement, the request of new features and bugs report are especially important to keep improving the project.

This project would like to thank Dipl. Biol. William Thielicke and Prof. Dr. Eize J. Stamhuis for sharing the codes and GUI of PIVlab.

MAIN FEATURES

Particle Tracking Algorithms:

* Particles detection based on Binary correlation, Gaussian mask and Dynamic Threshold Binarization techniques.

* Cross-correlation and Relaxation algorithms for solution of temporal matching problem.

* Particle labelling and tracking of individual trajectories.

Pre and Post-processing:

* Extraction of image background to improve SNR.

* Multiple vector validation methods.

* Data smoothing.

* Extraction of time series.

* Interpolation of the results on a regular mesh for standard Eulerian analysis.

* Calculation of streamlines
        Graphical User Interface (adapted from PIVlab):

* Extensive data extraction tools.

* Synthetic PIV/PTV image generator.

* Several data export features.

* Import bmp/ tiff/ jpeg image pairs/ series.

* Individual image masking and region of interest.

* Multiple colormaps.

Great software, Thanks a lot!
The only problem I am finding is that, if in a frame there is no particle, it does not process the whole frame sequence.

Ooops! Actually there are problem simular in the case of Alessandro

It works with Matlab 2015 without any errors.

To everyone in this post...

Note the MATLAB release for the software... (2008a). I believe it lost functionality when MatLab v8.0 came out (2012). For previous versions it works well.

I have MATLAB 2015b and i am getting the same errors as Alessandro with regards to the filepath.
Is there a newer version available that will work on 2015b?

Alessandro, what version of matlab are you using? I got the same problems with Matlab 2015b, but when I changed to Matlab 2014b I was able to use some of the functions.

It doesn't even work with the images provided...

It keeps rising an error:
