motion estimation Last modified: Monday, March 12, 2007

In video editing motion estimation is a type of video compression scheme. The motion estimation process is done by the coder to find the motion vector pointing to the best prediction macroblock in a reference frame or field. For compression redundancy between adjacent frames can be exploited where a frame is selected as a reference and subsequent frames are predicted from the reference using motion estimation. The motion estimation process analyzes previous or future frames to identify blocks that have not changed, and motion vectors are stored in place of blocks. The process of video compression using motion estimation is also known as interframe coding.

Motion Estimation Tutorial This page is intended to give the reader a basic understanding of what motion estimation is and how it fits into video compression as a whole. Motion Vector Applications We use these vectors creatively to detect and track motion and to find an alternative to traditional video decoding using phase shifting. motion-compensated coding (PDF) Prediction formulas and examples.
