Study Notes

Motion Estimation and Compensation

Motion estimation aims to obtain the motion vectors that describe the movement of objects in an image sequence.
The primary purpose of motion estimation is to enable motion compensation, which achieves data compression by predicting the current frame from the previous one.

Purpose of Motion Analysis

The primary purpose of examining the movement of objects in an image sequence is to reduce the redundancy between consecutive frames, enabling efficient video compression.
