This free Matlab toolbox contains a graphic user interface to scan and visualize series of images and data fields (vectors and scalars). It provides statistics and various processing for these data. It also contains a graphic user interface to run the Correlation Image Velocimetry software CIVx and analyze its results.
Prerequisit:
This toolbox requires Matlab, release R 13 or more recent. It can be run with any computer system on which Matlab is installed (in particular Linux and Windows). The image processing toolbox of Matlab provides useful complements but is not mandatory. To read velocity fields provided by the CIVx software, an additional toolbox for reading and writting netcdf files must be installed. It can be freely downloaded from http://mexcdf.sourceforge.net .
Installation:
Download the following archive and expend it into a directory UVMAT. Details for installation are provided by the text file README_INSTALL.txt in this directory. For performing PIV computations, binary files must be also downloaded from civX.
