| sassign is C++ and Matlab package for tracking larger numbers of
closely positioned cells (landmarks) with similar geometrical
characteristics through timeseries of frames where some cells may divide
into two daughter cells. Each frame may contains repositioned cells from the previous frame with
some of them divided into two parts, and/or a few number of outliers e.g. cells appeared/disappeared from the
boundaries of the frame or miscounted due to preprocessing errors. The C++
processing module is based on an advanced version of the softassign
algorithm where simulated annealing is used to minimize a global target
function over all possible parent-parent or parent-daughters associations of
cells. The Matlab part of the
package consists of wrapper routines for running the code and building hierarchical tree of the cells
