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:
“Too many Broadway actors in motion pictures lost their grip on success—had a feeling that none of it had ever happened on that sun-drenched coast, that the coast itself did not exist, there was no California. It had dropped away like a hasty dream and nothing could ever have been like the things they thought they remembered.”
—Mae West (1892–1980)
“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)
