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.
