Abstract

A new technique to reduce the effect of quantization in pulse code modulation image coding is presented. The technique consists of Roberts's pseudonoise technique followed by a noise reduction system. The technique by Roberts effectively transforms the signal dependent quantization noise to a signal independent additive random noise. The noise reduction system that follows reduces the additive random noise. Some examples are given to illustrate the performance of the quantization noise reduction system.
