Motion Compensation
Motion Compensation
Motion compensation is a set of techniques that take advantage of redundancy
in consecutive video frames. The se techniques are used in video processing
applications such as video compression and video stabilization. For both of
these applications, motion compensation is a two-ste p process of detection and
compensation. The detection step results in the specification of a m otion
vector that relates two consecutive video frames. For video compression, the
compensation step involves using the motion vector to predict the curre nt
video frame from the p revious frame and encoding the prediction residual.
For video stabilization, the compensation step involves translating the
current frame in the opposite direction of the motion vector to stabilize the
video sequence.
