Abstract

This paper reports on the authors' recent work in developing a new multirate method for image coding at low bit rates. The method follows the approach which was introduced at ISCAS 89 [1] and is based on a multirate maximally decimated filter bank structure. Difficulties and solutions related to the performance of the system are discussed in this paper. The proposed structure attempts to preserve the perceptually significant characteristics of the reconstructed image in the presence of quantization. Methods for coding the new multirate representation are still under development. However, preliminary coding results are shown in this paper using vector quantization and adaptive differential PCM. Results based on a more efficient contour encoding method will be presented at the conference.
