ABSTRACT:
An apparatus and a concomitant method for encoding video frame sequences (input images) using overlapping block motion compensation in conjunction with zerotree wavelet coding. The method partitions each input image into a plurality of overlapping blocks and applies wavelet transform on the partitioned input image. Various optional quantization processes can be selectively applied to determine an optimal quantizer scale for each wavelet coefficient. Zerotree coding is then optionally applied to selectively prune the wavelet coefficients. Finally, the quantized coefficients are encoded into a bitstream.
