Trends of High Quality Still Image Coding

Abstract

Digital image information plays an important role in multimedia systems. In this article, we describe recent technologies for high quality still image coding and communication. A growing number of new applications require additional functionalities from a compression standard, which either are not offered by JPEG, or if offered, not in the desired from. The new compression standard JPEG 2000 is designed to satisfy such requirements.
We also describe the research on “extra high quality audio-visual system for creation of future V-A works and tow-way presence communication.” This system aims to present extra high quality audio-visual information which can evoke our deep impression.
