Book Description
In the effort to digitize the battlefield, one of the most difficult capabilities to provide is the reliable transmission of imagery across the data links available. The most severe obstacles occur at low echelons, where the communication link is provided by combat net radios. The low-bandwidth, noisy nature of this physical channel represents the most serious challenge to implementation of the digital battlefield of the future. These channels make the compression of any imagery a requirement for timely transmission. In this paper, we explore the effects of noise on a variety of image compression techniques - namely, fractal, wavelet, DPCM, and the most recent compression standard for still imagery, JPEG version 6. Methods for minimizing the effects of the noisy channel on algorithm performance are also considered.

Book Description
This initial phase of the effort is focused on developing and understanding appropriate definitions, tools, and methods applicable to the problem of providing reliable information in highly dynamic physical and communication environments. A fundamental criterion of the "defining" phase is to apply compatibly efficient methods and to investigate relationships within the available information space that are hierarchical in their segmentation, assignment and processing of information. This process establishes a foundation for the objectivication of the underlying properties in the information space that is consistent with the capabilities provided by the methods and tools used to extract, enhance, or verify the information. Ultimately, this should lead to an information alphabet that allows rapid identification objects within the information environment. As applied to this project, the alphabet and the associated syntax for building objects, will be used to define, and hence reduce, the impacts and effects created by noise in the information gathering, and transmission processes. This formulation of the information environment will also be applicable to other object related activities, such as, compression, identification, tracking, and enhancement, and thus, will provide a computationally efficient foundation for various information processing activities in highly dynamic environments, such as those anticipated for UCAV or hypersonic missile systems.

Book Description
In today's digital world, images are often subjected to noise due to various factors such as low lighting, camera sensors, or image compression. This noise can greatly reduce the quality and clarity of the image, making it difficult to interpret or use for various applications. Therefore, enhancing noisy images has become an important topic of research. One approach to this problem is the use of multi-wavelet compression techniques. These techniques employ a combination of wavelet transformations to compress and reconstruct the image while simultaneously removing noise. Multi-wavelet compression techniques are particularly effective in reducing noise without losing image detail, resulting in a clearer and more accurate image. The effectiveness of these techniques has been demonstrated in various applications, such as medical imaging, remote sensing, and surveillance. Additionally, they can be used to enhance images captured in low-light environments or with low-quality sensors. In summary, multi-wavelet compression techniques provide a powerful tool for enhancing noisy images and improving their quality and clarity for a wide range of applications.

Book Description
JPEG2000 Standard for Image Compression presents readers with the basic background to this multimedia compression technique and prepares the reader for a detailed understanding of the JPEG2000 standard, using both the underlying theory and the principles behind the algorithms of the JPEG2000 standard for scalable image compression. It introduces the VLSI architectures and algorithms for implementation of the JPEG2000 standard in hardware (not available in the current literature), an important technology for a number of image processing applications and devices such as digital camera, color fax, printer, and scanners.

Book Description
Multimedia services involve processing, transmission and retrieval of multiple forms of information. Multimedia services have gained momentum in the past few years due to the easy availability of computing power and storage media. Societyisdemandinghuman-likeintelligentbehaviour,suchasadaptationand generalization, from machines every day. With this view in mind, researchers are working on fusing intelligent paradigms such as arti?cial neural networks, swarm intelligence, arti?cial immune systems, evolutionary computing and multiagents with multimedia services. Arti?cial neural networks use neurons, interconnected using various schemes, for fusing learning in multimedia-based systems. Evolutionary c- puting techniques are used in tasks such as optimization. Typical multiagent systems are based on Belief-Desire-Intention model and act on behalf of the users. Typical examples of intelligent multimedia services include digital - braries, e-learning and teaching, e-government, e-commerce, e-entertainment, e-health and e-legal services. This book includes 15 chapters on advanced tools and methodologies pertaining to the multimedia services. The authors and reviewers have c- tributed immensely to this research-oriented book. We believe that this - search volume will be valuable to professors, researchers and students of all disciplines, such as computer science, engineering and management. We express our sincere thanks to Springer-Verlag for their wonderful e- torial support.
