Variable bit rate vector quantization of video images for packet-switched networks

The authors investigate a novel vector-quantized compression strategy that provides guaranteed image quality with variable bit rate and show its applicability to packet-switched networks. This preliminary study indicates that significant improvements in both picture quality and SNR value can be achieved. The technique can be refined by reducing the number of overhead bits for each block and by separating coding schemes and high/low detail thresholds for each block size.<>
