Bit Allocation and Quantization for Transform Coding

  • Paul Michael Farrelle

Abstract

The most important part of a transform coding scheme is undoubtedly the bit allocation and quantization. True, there are good and bad transforms, there is straight transform coding and there is RBC, but whichever choice you make for the overall algorithm it will only be as good as the quantization scheme allows. In other words, a good transform and bad quantizer may well perform worse than a bad transform with a very good quantizer—but what do we mean by good and bad?
