JPEG2000 is the latest image compression standard to emerge from the Joint Photographic Experts Group (JPEG) working under the auspices of the International Standards Organization. Although the new standard does offer superior compression performance to JPEG, JPEG2000 provides a whole new way of interacting with compressed imagery in a scalable and interoperable fashion. This paper provides a t...

JPEG2000 is the new standard for the compression of images, which succeeds to JPEG. This standard is motivated primarily by the need for compressed image representations that offer new features increasingly demanded by modern applications, and also offering superior compression performance, especially at low bit-rates. This new standard has many features and characteristics (region of interest,...

Introduction: The JPEG2000 standard [1] has shown better performance than the widely used JPEG standard [2]. Nevertheless, efforts to improve JPEG2000 never stop. Long et al. [3] modified the quantisation step-size selection schemes for the uniform scalar quantisation used in JPEG2000 to improve the lossy compression. Lian et al. [4] proposed two skipping methods applied to the embedded block c...

JPEG2000 is the new standard for the compression of still images. Its objective and subjective image quality performance is superior to existing standards. In this paper the Part I of the JPEG2000 standard is presented in brief, and its implementation complexity on different computer platforms is reported.

With increasing usage of fingerprints as an important biometric data, the need to compress the large fingerprint databases has become essential. The most recommended compression algorithm, even by standards, is JPEG2000. But at high compression rates, this algorithm is ineffective. In this paper, a model is proposed which is based on parallel lines with same orientations, arbitrary widths and s...

A key aspect of image coding systems is the probability model employed to code data. The more precise estimates inferred by model, higher efficiency achieved. In general, models adjust after every new symbol. main difficulty apply such a strategy highly parallel engine that many symbols are coded simultaneously, so adaptation requires different approach. in previous works utilizes stationary co...

In this paper, a robust image transmission scheme based on JPEG2000 is proposed for packet erasure channels. Error resilience functionalities provided by JPEG2000 are utilized to control the source coding efficiency and the robustness according to channel conditions. Furthermore, together with the proposed interleaving scheme, some erasures can be recovered. Experimental results show the effect...
