Chapter 17. JPEG2000 Standard For Image Compression

Summary

JPEG2000 is the new international standard for image compression. Although JPEG (actually baseline JPEG) has been very successful in the marketplace for more than a decade, it lacks many features desired by interactive multimedia applications, its usage in current communications (wired or wireless) environments, and Internet applications platforms. A fundamental shift in the image compression approach came after the discrete wavelet transform (DWT) became popular. The JPEG2000 standard is expected be effective in wide application areas such as the Internet, digital photography, digital library, image archival, compound documents, image databases, color reprography (photocopying, printing, scanning, facsimile), graphics, medical imaging, multi-spectral imaging such as remotely sensed imagery, satellite imagery, mobile multimedia communication, 3G cellular telephony, client-server networking, e-commerce, etc. In this chapter, we introduce all the parts of new JPEG2000 standard. We have described in great detail the core coding algorithms for Part I of the standard in this chapter. We also presented results of JPEG2000 to show its superiority compared to the baseline JPEG standard for image compression.
