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 …

JPEG-2000 is an emerging standard for still image compression. This paper provides a brief
history of the JPEG-2000 standardization process, an overview of the standard, and some …

One of the aims of the standardization committee has been the development of Part I, which
could be used on a royalty-and fee-free basis. This is important for the standard to become …

A new image compression algorithm is proposed, based on independent embedded block
coding with optimized truncation of the embedded bit-streams (EBCOT). The algorithm …

We evaluate the applicability of a biologically-motivated algorithm to select visually-salient
regions of interest in video streams for multiply-foveated video compression. Regions are …

With information and scale as central themes, this comprehensive survey explains how to
handle real problems in astronomical data analysis using a modern arsenal of powerful …

State of the art, real-time, rate-adaptive, multimedia applications adjust their transmission
rate to match the available network capacity. Unfortunately, this source-based rate …

Data compression is one of the main contributing factors in the explosive growth in
information technology. Without it, a number of consumer and commercial products, such as …

The hand is quicker than the eye. In many cases, so is digital video. Maintaining image
quality in bandwidth-and memory-restricted environments is quickly becoming a reality as …

Multimedia data security is very important for multimedia commerce on the Internet such as
video-on-demand and real-time video multicast. Traditional cryptographic …
