Abstract

Several methods to perform subband coding of video sequences are studied. The subband decomposition can be used in coding the error frames as well as in estimating the motion in the image sequence. When motion compensation was not used, subband coding was found to offer numerical and subjective improvement over DPCM coding alone. Robust motion estimation using the pel recursive motion estimation was performed with the QMF pyramid in a hierarchical structure. A method for subband coding the residue in a hierarchical motion estimation environment is given. This method gave stable and better SNRs over non-subband coding schemes. Finally motion compensated interpolation and extrapolation are studied using subband coding and motion estimation schemes.
