Motion compensation — is an algorithmic technique employed in the encoding of video data for video compression, for example in the generation of MPEG 2 files. Motion compensation describes a picture in terms of the transformation of a reference picture to the current… … Wikipedia
Motion (physics) — Motion involves change in position, such as in this perspective of rapidly leaving Yongsan Station In physics, motion is a change in position of an object with respect to time. Change in action is the result of an unbalanced force. Motion is… … Wikipedia
Motion blur — is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single frame, either due to rapid movement or… … Wikipedia
