System object: vision.PointTracker
Set points to track
setPoints(H,POINTS) sets the points for
tracking. The method sets the M-by-2
of [x y] coordinates with the points to track. This method can be
used if the points need to be re-detected because too many of them
have been lost during tracking.
lets you mark points as either valid or invalid. The input logical
POINT_VALIDITY of length M,
contains the true or false value corresponding to the validity of
the point to be tracked. The length M corresponds
to the number of points. A false value indicates an invalid point,
and it should not be tracked. You can use this method with the
to determine the transformation between the point locations in the
previous and current frames, and then mark the outliers as invalid.
