No specific Matlab version is recorded. manTrack.m uses imshow,
which requires Matlab's Image Processing Toolbox.
manTrack.fig is a GUIDE layout file and must be kept in the same
folder as manTrack.m -- launch the GUI by running manTrack from
Matlab.
changeImage.m and manTrack.m call Gauss2D, which is not included
in this repository; it is available in other repositories in this
account (e.g. InstantaneousFlowTracker).
