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 کاملJpeg2000: Image Quality Metrics
High-resolution digital images that are used in geo-spatial and remote sensing technologies tend to be of large sizes, especially with newer satellite imageries that provide better than 5 m spatial resolution, and thereby consuming large storage space, large transmission bandwidth, and long transmission times. Therefore, method of compressing the archived images is required before storage and t...
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 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...
