Particle Tracking - new version (march 23, 2009)
This plugin is designed to track individual objects using a cross correlation method. It works with an ImageJ stack. It also performs statistics on the trajectories found.
Requirements : This plugin was successfully tested with ImageJ 1.41o but should work with older versions. It works on MacOS X, Linux and Windows, the installation procedure is described for each OS in the README-install.txt file.
Installation : Download tracker_install.zip archive and unzip it. Copy the package folder to the ImageJ folder and the tracker folder to the plugins folder of ImageJ. You now have to change the class path option of ImageJ (See README-install.txt file for instructions)
Usage : Initial positions of objects are taken from the "Results" window. You can use the standard "Points selections" Tool and click on objects to track on the first slice to fill the result window (you must choose a "Mark Width" of 0 and select the "Auto-Measure" option of the Tool). To use this plugin you must use a macro. A macro exemple file name "MacroTest.txt" can be found in the tracker folder. It encapsulates elementary macro commands in macro functions and automatizes the process.
