Motion estimation plays an important role in video coding
schemes by removing temporal redundancies that exist
in image sequences. Motion information that is required
in motion compensated prediction is transmitted as side
information, as in forward motion estimation, or can be
computed at the receiver in backward motion estimation.
The former method has the advantage of more accurate
prediction but, suffers in that the motion information is
transmitted as side information. We introduce the Motion
Transform (MT), a new motion estimation and compensation
technique that does not require the transmission of motion
vectors yet, performs well under a variety of conditions.
In the proposed method, motion information is obtained in
a bottom-up hierarchical fashion using a two-dimensional
