With the demand for utilizing Adaptive Vision Algorithms (AVAs) in embedded devices, serious challenges have been introduced to vision architects. AVAs may produce huge model data traffic while continuously training the internal model of the stream. This traffic dwarfs the streaming data traffic (e.g. image frames), and consequently dominates bandwidth and power requirements posing great challe...

The storage and bandwidth requirements of digital video and audio exceed those that can be supported by conventional file servers. Despite the emergence of new compression algorithms capable of providing extremely high compression ratios, typically in the region of 50:1, there is still a challenge to provide optimised storage services capable of storing 1000s of hours of multimedia data and pro...

Due to bandwidth constraints on the wireless link in an IP network, it is useful to compress the headers so as to maximize the utilization of the link. Different Header Compression schemes have been proposed. Some make use of the similarity in consecutive headers in a packet flow to compress these headers. These are called here time compression, as they acquire the compression information over ...

The networked visual sharing application in multi-party collaboration environment needs compression of video streams due to network bandwidth limitation. For interactive real-time sharing, real-time compression of high-quality video as well as audio echo cancellation are required, which commonly depend on the availability of high-cost hard-to-setup specialized compression and echo-cancellation ...

The overall objective of this paper is to review various image compression techniques. Image compression has become very important tool in digital image processing. The main objective of the compression is to reduce the amount or unwanted data while retaining the information in the image. The goal behind is to save the amount of memory required to save the image(s) or to utilize network bandwid...

Since the introduction of Internet-enabled devices such as video cameras, phones and PDAs, the bandwidth requirements of each device continue to become more varied. Even devices that provide the same types of functionality tend to use di erent amounts of bandwidth. For example, cameras that use motion-JPEG compression tend to consume more bandwidth than cameras which use MPEG compression. These...

With the emergence of the International Telecommunication Union’s (ITU) H.263 video coding standard, real-time visual communications over low-bandwidth, low-error-rate wired telephone networks is now possible. Unfortunately, because of the nature of the algorithms employed within this compression standard and due to the inherent limitations of the radio environment, H.263 coded video performs p...

Compression is widely used in storage systems to reduce the amount of data that is written to physical storage devices, in order to improve both bandwidth and price per GB. In SSDs, which use NAND flash devices, compression also helps to improve endurance, which is limited to a fixed number of raw bytes written to the media, and to reduce garbage-collection overheads. Compression is typically i...

Integrated design of digital compression and modulation ooers performance advantages in practical systems over separate optimization. Integrated system design encourages more general compression deenitions. The total digital integrated transmission system is in this article viewed as an analog-to-analog converter with signal compression ability. A new deenition for compression is presented, inc...
