+The multitemporal association tracker [1] is a multitarget tracking system,
+this version has a cost function which was developed for tracking cells in 2D,
 though it would not be difficult to modify the cost function for 3D.
 
 This directory includes Visual Studio 2008 solution files, but the underlying
 tracker should build on other platforms if necessary.
