Reducing blurs and color streaks in the video
If the experimental subject moves quickly, blurs and color streaks
can appear in the video. Reduce or eliminate these problems by

6 In the Object Contour Tracker area, click Show Contour/Fill Contour to
view the contour(s) of the object(s) that the system is tracking.
