JPEG2000 - A whole new philosophy in Still Image Coding
Amitava Das
Shailesh Ramamurthy
Sunday May 26, 2002, 8:30 AM - 11:45 AM

Abstract:

JPEG2000 (ISO/IEC 15444), the new generation still image coding technology, offers a unified coding framework for a variety of still image types (bi-level, gray-scale, color, multi-component) with very different characteristics (natural, scientific, medical and remotely sensed images, text, rendered graphics, etc). Areas where this technology scores over existing still image coding standards include superior low bit-rate operation, progressive spatial as well as quality scalability, transmission in noisy environments, Region of Interest Coding, and, a unified system for lossy and lossless coding.

This tutorial covers the algorithmic and implementation aspects of JPEG2000, and includes the following modules:

  • Introduction to JPEG2000
  • Data ordering and Code-Stream assembly in JPEG2000
  • The Wavelet Transform
  • The Coefficient Bit Modeler and Arithmetic Coder
  • Rate Control in JPEG2000 - an overview
  • Future directions

Apart from the theoretical aspects covered in this tutorial, the concepts will be illustrated with relevant examples and demonstrations. This tutorial targets engineers, researchers and hardware designers interested in JPEG-2000 technology.
