The JPEG2000 still image coding system: an overview
With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a new standard is currently being developed, the JPEG2000. It is not only intended to provide rate-distortion and subjective image quality performance superior to existing standards, but also to provide feat...

متن کاملAn efficient optimal rate control scheme for JPEG2000 image coding
Most of the computation and memory usage of the post-compression rate-distortion (PCRD) optimization scheme in JPEG2000 are redundant. In this paper, an efficient rate PCRD scheme based on priority scanning (PS) is proposed to alleviate the problem. By encoding the truncation points in a different order based on the priority information, the proposed method can efficiently reduce the redundancy...
متن کاملParallel JPEG2000 Image Coding on Multiprocessors
In this paper, we discuss how the two reference implementations of the upcoming JPEG2000 image coding standard can be parallelized for the execution on sharedmemory multiprocessors. By runtime analysis, we identify two major stages in the coding process of JPEG2000 where parallelism can be exploited. We present techniques to exploit the parallelism within these two stages, and speedup results o...
متن کاملAn overview of the JPEG 2000 still image compression standard
In 1996, the JPEG committee began to investigate possibilities for a new still image compression standard to serve current and future applications. This initiative, which was named JPEG 2000, has resulted in a comprehensive standard (ISO 154447ITU-T Recommendation T.800) that is being issued in six parts. Part 1, in the same vein as the JPEG baseline system, is aimed at minimal complexity and m...
