The invention is a process to compare two digital images (and usually
more) and to identify objects in each image. After object identification,
object descriptors are formed. The object descriptors of the objects in
one frame are compared to those of objects in the second frame, allowing
the tracking of an object in the two frames. The movement of each tracked
object within the two frames is quantified, and the second frame is
corrected to account for the object's movement.
