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.
