Abstract :
We present a novel pel-recursive motion compensation scheme. The new scheme incorporates vector quantization into pel-recursive motion compensation by using a code excited analysis-by-synthesis coding structure. Our experiments demonstrate that the proposed scheme achieves 4-7 dB PSNR gains or equivalently 40-50% bit savings over the conventional scalar quantizer based pel-recursive motion compensation scheme
