Abstract :
Research on wavelet image coding yielded the ISO/ITU JPEG 2000 standard. Although JPEG 2000 provides improved compression, the its great are progressive resolutions, bit-rate control (or quality control), and regions of interest. What does this suggest for the future of image coding? Should the old requirements (smaller files, faster transmission) be replaced? Perhaps it is time to view still image coding in the larger context of image communication considering such functionality such as access, enhancement, restoration, editing, understanding, security, indexing, and distribution. This paper surveys recent research with respect to these features and suggests future requirements for image coding systems.
