Abstract:

A new technique to reduce the effect of quantization in PCM image coding is presented in this report. The new technique consists of Roberts 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 new quantization noise reduction system. Author
