Abstract
A differential pulse code modulation (DPCM) coding technique called “block” DPCM is proposed. It attempts to achieve a bit rate below 2.0 bits/pixel without using adaptive methods. Two slightly different schemes called “maximum” block DPCM and “sequential” block DPCM are introduced. Linear interpolation is used to fill in untransmitted samples. Filtering is also applied in order to improve image quality. The performance of these two schemes are evaluated by simulation results.
