摘要

作者将DPCM(差分脉冲编码调制)应用于金字塔编码策略，并表明，对于实际的量化器，需要比常规DPCM更低的比特率才能获得高质量的图像。金字塔DPCM相对简单、可行，并且允许样本之间的处理间隔长于采样间隔。本文还讨论了一种可以大大降低编码比特率的多分辨率分组方案。

Hierarchical image coding with pyramid DPCM

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.<>
