Abstract

For many contemporary applications, such as distributed multimedia systems, rapid transmission of images is necessary. Cost of transmission and storage tends to be directly proportional to the volume of data. Therefore, application of digital image compression techniques becomes necessary to minimize the cost. A number of digital image compression algorithms have been developed and standardized. The method proposed by Joint Photographic Experts Group (JPEG) is a lossy compression technique. An improved version of JPEG is JPEG2000, which is currently the most popular compressor. The paper deals with a new compressing non-negative integer method JPEG2000 with Gamma code compressors by modifying the JPEG2000 architecture. In the proposed methods, the entropy coder is replaced by new coders. Simulated experiments using the methods show that proposed methods gives better image quality when compared to the JPEG2000 at any given bit rate.
