Abstract
The authors apply DPCM (differential pulse code modulation) to pyramid coding strategy, and show that, for practical quantizers, lower bit rates than regular DPCM are required for high-quality resulting images. The pyramid DPCM is relatively simple, feasible, and allows a processing interval between samples that is longer than the sampling interval. A blockwise scheme for multiresolution which could largely decrease the coding bit rate is also discussed.Keywords
