Abstract
The conventional scalar-quantizer-based pel-recursive motion compensated coding scheme is enhanced by incorporating vector quantization. The enhanced scheme uses code-excited analysis-by-synthesis to quantize the motion compensated prediction residual. Simulation results show that the enhanced scheme furnishes large rate-distortion performance gains over the conventional scheme, particularly at bit rates below about 0.5 bits per pixel.
