This program performs tracking of objects depending on their color. In this particular case, the tracking is performed upon yellow objects.
The blue square encloses the limits of the detected object.
The red line marks the path followed by the center of the object. It shows the last 100 locations. When the object is not detected, the oldest samples are progressively removed.
The green square, which is centered around the location of the central pixel of the object, shows the neighborhood in which we will look for the object in the next iteration. That is, if we don't find a trackable object in the scanned area, in the next iteration we will scan the whole image. But if we found it, in the next iteration we will look only in the neighborhood.
