- Abstract
- In the field of the coding of digital video signals, the concept of hierarchical coding is of real interest. Decorrelation operators fulfilling that hierarchical requirement are subband operators and pyramidal systems. The aim of this paper is show that the same methodology can be used to solve the quantization problem in subband and pyramidal coders. The criterion considered here takes into account the eye sensitivity to spatial frequencies. An analytical approach is presented in that paper for the cases of fixed bit allocation and quantizer followed by an entropy coder.
