The forward motion estimation, the bilateral motion compensated interpolation and the motion vector correction techniques using weighted median filters are used to generate the side information.
Then, the decoding of a WZ frame is performed by first generating a side information (SI), that is an estimate of the missing frame, usually obtained by motion compensated interpolation between two adjacent previously decoded key-frames.
However, translational motion is easily estimated and has been used successfully for motion compensated coding.
To recover higher-frequency components in temporal domain, motion compensated interpolation algorithms have been proposed and they usually employ a BMA to estimate MVs for moving objects[4, 7 9, 17 20].
(6) The decoder creates the so-called side information (SI) for each WZ frame, which should be a good estimate of the original WZ frame [9], by performing a motion compensated frame interpolation process, using the previous and next decoded frames temporally closer to the WZ frame under coding.
Motion compensated prediction (MCP) implemented in most video coding schemes is based on translational motion model.

This architecture can further speed up the transcoding process of the motion compensated macroblocks.
Thus, SI is created from a codebook (CB) rather than by motion compensated prediction.
A conventional video codec uses encoder reconstruction of previous frames for motion compensated prediction.
Recently, there have been a flurry of works on overcomplete motion compensated wavelet coding (OMCWC).
