High-band signals in motion estimation and compensation techniques for wavelet video coding
This paper investigates motion estimation and compensation techniques over spatial domain on wavelet video coding. In particular, we concentrate on high-band signals on prediction error which are key factors for a high coding efficiency, especially with wavelet transform. Moreover, we analyze the video coding performance according to computational complexity and motion estimation error. Finally, four types of motion estimation and compensation methods are investigated and we observe that overlapped block motion compensation and mesh-based algorithm generate smoother motion field.
