Implementation of JPEG-2000 standard for the next generation image compression

Abstract

With the increasing use of multimedia technologies, image compression requires higher performance as well as new functionality. This leads to the emerge of a new image compression standard, JPEG-2000. This project seeks to investigate the compression technique of JPEG-2000 standard. The project scope can be categorised into three areas, understanding of major functional blocks of JPEG-2000, setting up an simulation software in C/C++ programming language and investigate the algorithm's performance and computational complexity of the standard. The major functional blocks of JPEG-2000, such as discrete wavelet transform (DWT) and embedded block coding with optimised truncation (EBCOT), are particularly focused. The simulation software which consists of a Windows Bitmap and JPEG-2000 codestream transcoder is developed with additional function program to identify computational intensive blocks in the transcoder. A graphical user interface (GUI) is also incorporated to simplified transcoder usage. The execution time for compression and decompression of each functional block is investigated. A compatibility test is also carried out between the developed software and other software packages available in the market. In addition, JPEG- 2000 and JPEG computational complexity and image quality are compared.
