The demand for data traffic over mobile communication networks has substantially increased during the last decade. As a result, these mobile broadband devices spend the available spectrum fiercely, requiring the search for new technologies. In transmissions where the channel presents a frequency-selective behavior, multicarrier modulation (MCM) schemes have proven to be more efficient, in terms of spectral usage, than conventional modulations and spread spectrum techniques. The orthogonal frequency-division multiplexing (OFDM) is the most popular MCM method, since it not only increases spectral efficiency but also yields simple transceivers. All OFDM-based systems, including the single-carrier with frequency-division equalization (SC-FD), transmit redundancy in order to cope with the problem of interference among symbols. This book presents OFDM-inspired systems that are able to, at most, halve the amount of redundancy used by OFDM systems while keeping the computational complexity comparable. Such systems, herein called memoryless linear time-invariant (LTI) transceivers with reduced redundancy, require low-complexity arithmetical operations and fast algorithms. In addition, whenever the block transmitter and receiver have memory and/or are linear time-varying (LTV), it is possible to reduce the redundancy in the transmission even further, as also discussed in this book. For the transceivers with memory it is possible to eliminate the redundancy at the cost of making the channel equalization more difficult. Moreover, when time-varying block transceivers are also employed, then the amount of redundancy can be as low as a single symbol per block, regardless of the size of the channel memory. With the techniques presented in the book it is possible to address what lies beyond the use of OFDM-related solutions in broadband transmissions.

A straightforward, easy-to-read introduction to the finite-difference time-domain (FDTD) method Finite-difference time-domain (FDTD) is one of the primary computational electrodynamics modeling techniques available. Since it is a time-domain method, FDTD solutions can cover a wide frequency range with a single simulation run and treat nonlinear material properties in a natural way. Written in a tutorial fashion, starting with the simplest programs and guiding the reader up from one-dimensional to the more complex, three-dimensional programs, this book provides a simple, yet comprehensive introduction to the most widely used method for electromagnetic simulation. This fully updated edition presents many new applications, including the FDTD method being used in the design and analysis of highly resonant radio frequency (RF) coils often used for MRI. Each chapter contains a concise explanation of an essential concept and instruction on its implementation into computer code. Projects that increase in complexity are included, ranging from simulations in free space to propagation in dispersive media. Additionally, the text offers downloadable MATLAB and C programming languages from the book support site ( Simple to read and classroom-tested, Electromagnetic Simulation Using the FDTD Method is a useful reference for practicing engineers as well as undergraduate and graduate engineering students.

Field Programmable Gate Arrays (FPGAs) sind relativ komplexe programmierbare Logikbausteine. Mithilfe von FPGAs können mittlerweile jedoch auch Maker und Elektronikbastler eigene Chips entwerfen. Wie das geht, zeigt Ihnen dieses Buch. Zunächst wird erklärt, was FPGAs sind und wie sie funktionieren. Es folgt eine Einführung in die Hardwarebeschreibungssprache VHDL, die für die Projekte in diesem Buch verwendet wird. Danach wird Schritt für Schritt anhand zunächst ganz einfacher Beispiele erläutert, wie man eine Schaltung mithilfe eines FPGA realisiert. Im weiteren Verlauf werden die Schaltungen anspruchsvoller. Den Abschluss bildet ein Projekt, bei dem das Spiel »Pong« in Hardware realisiert wird. Die Anzeige erfolgt auf einem RGB-LED-Matrix-Display, dessen Ansteuerung per FPGA im Detail beschrieben wird. Die Projekte im Buch werden auf Basis kostenlos verfügbarer FPGA-Entwicklungsumgebungen der Hersteller Altera, Lattice, Microsemi und Xilinx sowie günstiger FPGA-Boards konkret umgesetzt. Dabei wird auf die Übertragbarkeit auf andere Systeme geachtet. Die verwendeten Entwicklungsumgebungen und FPGA-Boards werden außerdem kurz vorgestellt. Cord Elias konzentriert sich primär auf die Vermittlung von Fähigkeiten zum selbstständigen Umgang mit FPGAs. Er nimmt die Leserinnen und Leser an die Hand und leitet sie sicher durch eine Vielzahl von Details. Dass der Spaß dabei nicht zu kurz kommt, versteht sich von selbst. Der Quellcode zu allen Design-Beispielen steht zum Download bereit.

PREFACE In January 1978, I began the preface to the first edition of Digital Image Processing with the following statement: “The field of image processing has grown considerably during the past decade with the increased utilization of imagery in myriad applications coupled with improvements in the size, speed and cost effectiveness of digital computers and related signal processing technologies. Image processing has found a significant role in scientific, industrial, space and government applications.” In January 1991, in the preface to the second edition, I stated: “Thirteen years later as I write this preface to the second edition, I find the quoted statement still to be valid. The 1980s have been a decade of significant growth and maturity in this field. At the beginning of that decade, many image processing techniques were of academic interest only; their execution was too slow and too costly. Today, thanks to algorithmic and implementation advances, image processing has become a vital cost-effective technology in a host of applications.” In August 2000, in the preface to the third edition, I wrote: “Now, in this beginning of the twenty-first century, image processing has become a mature engineering discipline. But advances in the theoretical basis of image processing continue. Some of the reasons for this third edition of the book are to correct defects in the second edition, delete content of marginal interest, and add discussion of new, important topics. Another motivating factor is the inclusion of interactive, computer display xiv PREFACE imaging examples to illustrate image processing concepts. Finally, this third edition includes computer programming exercises to bolster its theoretical content. These exercises can be implemented using the Programmer’s Imaging Kernel System (PIKS) application program interface (API). PIKS is an International Standards Organization (ISO) standard library of image processing operators and associated utilities.” Again, for a fourth time, a new edition of Digital Image Processing is offered to the image processing community. Why? One reason is because advances in the theoretical aspects of image processing technology continue at a rapid rate. For example, in the year 2005, the IEEE Transactions on Image Processing published 2191 pages of research papers. The IEEE Transactions on Pattern Analysis and Machine Intelligence was in close second place in 2005 with 2002 published pages. Add to that the content of independent journals, such as the John Wiley & Sons International Journal of Imaging Systems and Technology plus numerous image processing technical conferences. There is an enormous amount of new image processing technology to be absorbed. I have tried to act as a publishing filter by culling through the image processing literature since the third edition was published in 2002, and then abstracting what I think are the most important contributions. Details follow. Another reason for publication of the fourth edition of Digital Image Processing is to make available, at no cost, the PIKS Scientific API for educational purposes and for industrial software development. The PIKS Scientific software is on a CD affixed to the back cover of this book. PIKS Scientific includes implementations of most of the high-level operators in this book. The book is intended to be an “industrial strength” introduction to digital image processing to be used as a text for an electrical engineering or computer science course on the subject. Also, it can be used as a reference manual for scientists who are engaged in image processing research, developers of image processing hardware and software systems, and practicing engineers and scientists who use image processing as a tool in their applications. Mathematical derivations are provided for most algorithms. The reader is assumed to have a basic background in linear system theory, vector space algebra and random processes. Proficiency in C language programming is necessary for execution of the image processing programming exercises using PIKS. The book is divided into six parts. The first three parts cover the basic technologies that are needed to support image processing applications. Part 1 contains three chapters concerned with the characterization of continuous images. Topics include the mathematical representation of continuous images, the psychophysical properties of human vision, and photometry and colorimetry. No substantial changes have been made to this fundamental material. In Part 2, image sampling and quantization techniques are explored along with the mathematical representation of discrete images. A new section on Color Image Sampling Systems, such as the Bayer color filter, has been added to Chapter 4. Part 3 discusses two-dimensional signal processing techniques, including general linear operators and unitary transforms such as the Fourier, Hadamard, Daubechies and Karhunen–Loeve transforms. The final chapter in Part 3 analyzes and compares PREFACE xv linear processing techniques implemented by direct convolution and Fourier domain filtering. The next two parts of the book cover the two principal application areas of image processing: Image Improvement and Image Analysis. Part 4 presents a discussion of image enhancement and restoration techniques, including restoration models, point and spatial restoration and geometrical image modification. Chapter 10 on Image Enhancement contains new material on Contrast Manipulation, Histogram Modification Noise Cleaning and Color Image Enhancement. Content on Blind Image Restoration and Multi-Plane Image Restoration has been added to Chapter 12, Image Restoration Techniques. A new section on Polar Coordinate Conversion has been included in the chapter on Geometrical Image Modification. Part 5, entitled Image Analysis, concentrates on the extraction of information from an image. Specific topics include morphological image processing, edge detection, image feature extraction, image segmentation, object shape analysis and object detection. Additional material on Structuring Element Decomposition has been included in the Morphological Image Processing chapter. The sections on First Order Derivative Edge Detection and Color Edge Detection in Chapter 15 have been augmented. Material has been added on Texture Features in Chapter 16. In the chapter on Image Segmentation, material has been added on Amplitude, Region, Boundary and Texture Segmentation. New content on Distance, Perimeter and Area Measurements has been added to the Shape Analysis chapter. A new section on Non-morphological Thinning and Skeletonizing has been included in the chapter. Finally, new material has been added on Template Matching and Image Registration in Chapter 19. Part 6 discusses the software implementation of image processing applications. This part describes the PIKS API and explains its use as a means of implementing image processing algorithms. Image processing programming exercises are included in Part 6. Throughout the first 19 chapters on the theoretical basis of image processing, upto- date references of papers judged to be of significance have been included as a guide for extended study. Although readers should find this book reasonably comprehensive, many important topics allied to the field of digital image processing have been omitted to limit the size and cost of the book. Among the most prominent omissions are the topics of pattern recognition, image reconstruction from projections, image understanding, image coding, scientific visualization and computer graphics.
