Abstract :
The notion of multiresolution signal analysis is used to develop motion estimation algorithms on a three-dimensional pyramid. The motion vectors are then used to interpolate a sequence at a higher resolution, and the difference is coded as an error signal to guarantee very-high-quality coding. This process is repeated to generate a hierarchy of sequences. Such a scheme is well suited for compatible coding of HDTV (high-definition television). The performance of the motion estimation algorithm and of the coding at 100 Mb/s is described
