Automatic video tracking is a technique of automatically locating a moving object over time within recorded video frames. The image in this post is from a project, where I programmed a tracking algorithm in MATLAB to analyze the shrinkage dynamics of liver tissue during ablative temperature exposures. The algorithm located the tracking markers automatically based on a threshold criteria and identified them on
every thirtieth frame (= 1 second). The marker positions (centers) as well
as the distance between the two markers were stored and the relative shrinkage
in percent was estimated. A video that shows the automatic tracking procedure can be found here: http://www.youtube.com/watch?v=X_SnEULgH7M
