Motion Compensation - Motion Compensation in MPEG

Motion Compensation in MPEG

In MPEG, images are predicted from previous frames (P frames) or bidirectionally from previous and future frames (B frames). B frames are more complex because the image sequence must be transmitted/stored out of order so that the future frame is available to generate the B frames.

After predicting frames using motion compensation, the coder finds the error (residual) which is then compressed and transmitted.

Famous quotes containing the words motion and/or compensation:

    When desire, having rejected reason and overpowered judgment which leads to right, is set in the direction of the pleasure which beauty can inspire, and when again under the influence of its kindred desires it is moved with violent motion towards the beauty of corporeal forms, it acquires a surname from this very violent motion, and is called love.
    Socrates (469–399 B.C.)

    Many old people receive pensions for no other reason, it seems to me, but as a compensation for having lived a long time ago.
    Henry David Thoreau (1817–1862)
