Book Synopsis Subband Compression of Images: Principles and Examples by : T.A. Ramstad
Download or read book Subband Compression of Images: Principles and Examples written by T.A. Ramstad and published by Elsevier. This book was released on 1995-07-18 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixth in the book series, Advances in Image Communication, which documents the rapid advancements of recent years in image communication technologies, this volume provides a comprehensive exploration of subband coding.Originally, subband coding and transform coding were developed separately. The former, however, benefitted considerably from the earlier evolution of transform coding theory and practice. Retaining their own terminology and views, the two methods are closely related and this book indeed aims to unify the approaches. Specifically, the volume contributes effectively to the understanding of frequency domain coding techniques. Many images from coding experiments are presented, enabling the reader to consider the properties of different coders.Chapter 1 introduces the problem of image compression in general terms. Sampling of images and other fundamental concepts, such as entropy and the rate distortion function, are briefly reviewed. The idea of viewing coding techniques as series expansions is also introduced. The second chapter presents signal decomposition and the conditions for perfect reconstruction from minimum representations. Chapter 3 deals with filter bank structures, primarily those displaying the perfect reconstruction property. Quantization techniques and the efficient exploitation of the bit resources are discussed from a theoretical perspective in Chapter 4 and this issue is further examined in Chapter 6, from a more practical point of view. Chapter 5 provides a development of gain formulas, i.e. quantitative measures of the performance of filter banks in a subband coding context, and these are then employed in a search for optimal filter banks. A number of examples of coded images using different subband coders are presented in Chapter 7, these indicating that subband coders give rise to some characteristic types of image degradations. Accordingly, Chapter 8 presents several techniques for minimizing these artifacts. The theory and practice of subband coding of video, at several target bit rates, is discussed in the last chapter.
Book Synopsis Multiresolution Signal Decomposition by : Ali N. Akansu
Download or read book Multiresolution Signal Decomposition written by Ali N. Akansu and published by Academic Press. This book was released on 2001 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: The uniqueness of this book is that it covers such important aspects of modern signal processing as block transforms from subband filter banks and wavelet transforms from a common unifying standpoint, thus demonstrating the commonality among these decomposition techniques. In addition, it covers such "hot" areas as signal compression and coding, including particular decomposition techniques and tables listing coefficients of subband and wavelet filters and other important properties. The field of this book (Electrical Engineering/Computer Science) is currently booming, which is, of course, evident from the sales of the previous edition. Since the first edition came out there has been much development, especially as far as the applications. Thus, the second edition addresses new developments in applications-related chapters, especially in chapter 4 "Filterbrook Families: Design and Performance," which is greatly expanded. Unified and coherent treatment of orthogonal transforms, subbands, and wavelets Coverage of emerging applications of orthogonal transforms in digital communications and multimedia Duality between analysis and synthesis filter banks for spectral decomposition and synthesis and analysis transmultiplexer structures Time-frequency focus on orthogonal decomposition techniques with applications to FDMA, TDMA, and CDMA

Book Synopsis Advanced Video Coding: Principles and Techniques by : K.N. Ngan
Download or read book Advanced Video Coding: Principles and Techniques written by K.N. Ngan and published by Elsevier. This book was released on 1999-08-31 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the paradigm of video coding has shifted from that of a frame-based approach to a content-based approach, particularly with the finalization of the ISO multimedia coding standard, MPEG-4. MPEG-4 is the emerging standard for the coding of multimedia content. It defines a syntax for a set of content-based functionalities, namely, content-based interactivity, compression and universal access. However, it does not specify how the video content is to be generated. To generate the video content, video has to be segmented into video objects and tracked as they transverse across the video frames. This book addresses the difficult problem of video segmentation, and the extraction and tracking of video object planes as defined in MPEG-4. It then focuses on the specific issue of face segmentation and coding as applied to videoconferencing in order to improve the quality of videoconferencing images especially in the facial region. Modal-based coding is a content-based coding technique used to code synthetic objects that have become an important part of video content. It results in extremely low bit rates because only the parameters needed to represent the modal are transmitted. Model-based coding is included to provide background information for the synthetic object coding in MPEG-4. Lastly, MPEG-4, the first coding standard for multimedia content is described in detail. The topics covered include the coding of audio objects, the coding of natural and synthetic video objects, and error resilience. Advanced Video Coding is one of the first books on content-based coding and MPEG-4 coding standard. It serves as an excellent information source and reference for both researchers and practicing engineers.

Download or read book De-interlacing written by E.B. Bellers and published by Elsevier. This book was released on 2000-10-02 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'To interlace or not to interlace' is a hot issue currently. Traditionally interlace has been part of the video standard as it reduces the transmission and display demands, while hardly affecting the perceived quality of the pictures. With the current explosion of new video formats due to emerging technologies as multimedia PC's, videotelephony and flat matrix display the question whether or not interlace is a relict from the past is more relevant than ever. This book provides a broad overview of advanced motion estimation and de-interlacing techniques to enable a profound scientific basis for answering the above question. An extensive evaluation of the algorithms, including many screen photographs is an imt part of the book. But also system questions, such as whether interlace is a good choice in combination with modern video compression methods (MPEG), and which currently would be the optional choice for a display format are extensively treated. The combination of scientific profoundness and completions, with the focus on practical hot issues, makes the book unique in its kind.

Download or read book Three-Dimensional Electromagnetics written by P.E. Wannamaker and published by Elsevier. This book was released on 2002-07-08 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: "3-D modeling and inversion is a reality, and not an illusion." This is the clear conclusion of the Second International Symposium on Three-Dimensional Electromagnetics held at the University of Utah in 1999. Containing papers submitted by 36 authors, this volume, by the sheer number of works, their diversity, and the truly international character of the efforts attests to the vigor with which the problems of the field are pursued today.The papers in this book are grouped in three parts: 3-D EM modeling; 3-D EM inversion; and 3-D EM in practice. They cover a wide range of topics in forward modeling and inversion based on new fast approximate approaches and new efficient solutions by integral equation, finite difference and finite elements techniques. If the 1980s were the decade of rapid development in 3D seismics, the 1990s became the decade of growing interest of practical geophysicists in 3D EM modeling and inversion methods.The contributions contained in this volume represent a snapshot of today's state-of-the-art in three-dimensional electromagnetics.

Book Synopsis Subband and Wavelet Transforms by : Ali N. Akansu
Download or read book Subband and Wavelet Transforms written by Ali N. Akansu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientists and engineers of today are relentless in their continuing study and analysis of the world about us from the microcosm to the macrocosm. A central purpose of this study is to gain sufficient scientific information and insight to enable the development of both representative and useful models of the superabundance of physical processes that surround us. The engineers need these models and the associated insight in order to build the information processing systems and control systems that comprise these new and emerging technologies. Much of the early modeling work that has been done on these systems has been based on the linear time-invariant system theory and its extensive use of Fourier transform theory for both continuous and discrete systems and signals. However many of the signals arising in nature and real systems are neither stationary nor linear but tend to be concentrated in both time and frequency. Hence a new methodology is needed to take these factors properly into account.
