1. A method of performing semi-automatic tracking of colored objects within a video image sequence comprising the steps of:

  • separating objects within an initial frame of the video image sequence on the basis of color;

    receiving a user-provided input that selects an object of interest from the separated objects by a user identifying a centroid of the object of interest; and

    tracking the object of interest through successive frames of the video image sequence using a Kalman predictive algorithm applied to the centroid.
