Placing the tracker

The objective is now to select the image-level feature in the image sequence that will be tracked.

At this point you have decided what the tracker parameters are.

You can place the tracker inside the image by moving the cursor so that it is inside the image. Once you do that you will be able to see the tracker (a red rectangle).

Once you have decided where you will place it you should press and release the mouse button. This will initialize the tracker.

The reccomended positions for the three trackers are (first, second, third respectively):
