This is a basic cell tracker for use on uncompressed AVI files, ideal for use with videos where the image of the cell overlap much frame-to-frame. If you use it to generate data for publication please cite the conference paper in the readme file, which you might want to read anyway if you want to use. Sample video to track and paper available at lab website: bme.virginia.edu/lawrence. I'm working on a multiparticle version of the algorithm which also better tracks low-temporal resolution data and compressed input formats. I will post it when I work more of the bugs out. Please contact me if you are interested in the alpha version.
