Particle Identification and Tracking
This is an implementation in c++ of the particle tracking algorithms developed by Croker and Grier (http://dx.doi.org/10.1006/jcis.1996.0217). This algorithm has been implemented a number of times (see table). The primary advantage of the C++ implementation over IDL or MATLAB implementations is that C++ is significantly faster. On identical data the C++ code is at least ~20x than Dan Blair's MATLAB code.

The code is also being tracked on github. There is currently no 'stable' version of the code as I am still actively developing it.
are written and fully tested and
are partially written or tested.
The code for particle location and further processing of the locations are almost completely separate. The identification code is a modified version of Peter Lu's particle identification code. The most current version of PLuTARC, as well as a MATLAB wrapper for it, is available at http://plutarc.sourceforge.net/. The analysis code is newly developed.
Parameters are passed into the analysis programs via XML files. There is python code included to generate appropriate XML files.
The code can easily be extended for N-dimensions, but only 2 and 3 are currently implemented.
Input and output is done through a family of wrapper classes. With minimal new code basically any input/output format can be dealt with. There are wrappers written for HDF5 files and interacting with MATLAB.
The code is very modular and for the most part adding new computations to the framework only requires writing a single new subclass.
This code should be reasonably portable to *nix systems, but the library paths will need to be fixed, see INSTALL for directions and a list of required libraries. The some of the MATLAB related code will not work on a windows machine (there are lots of couts in the code which matlab in linux can cope with, but matlab on windows apparently can't (according to matlab documentation)), but I expect that the rest of the code (if it will compile) will work fine. To my knowledge this has not been tested.
