load device can be modeled as a resistor and enhancement devices can be modeled as switches.” In this reviewer’s opinion, this book does not offer indepth coverage of integrated circuit engineering. Given the intended audience, the authors, almost out of necessity, devote a large segment of the text to an introductory coverage of semiconductor materials and device physics. These topics are presented more clearlyandin more detail in other texts [ 5 ] , [6]. Fortunately, each chapter except the fnst contains an adequate bibliography. Indeed, without supplementary reading, it will be difficult for the newcomer to fully understand the material as the authors have presented it. In this reviewer’s opinion, the authors have attempted to accomplish too much in a single volume. REFERENCES [ 1 ] S. K. Ghandi, The Theory and Practice of Microelectronics.

The fifth and sixth chapters deal with the problems of extracting and tracking one or more objects which are moving in time. Chapter 5 addresses the question “In real-world scenes, at what level of abstraction should images be compared?” The author’s answer to this difficult question is a multilevel approach in which regions areextracted in each frame, and attributes are defined and then utilized to link objects in time. Chapter 6 begins with a discussion of the general problem of occlusion, and then presents a number ofsystemsgeared toward increasing one’s understanding of occlusion, especially in the case of time-varyingimages.The systems are of two types: those using dot pattern analysis and those using edge and boundary analysis. Finally, chapter 7 gives a comprehensivesurveyof the application of image sequence analysis to medicine. The three categoriesconsidered are: the extraction of measurements from X-ray image time sequences, the generation of functional images, and imageenhancement. I m g e Sequence Analysis will be of geat value to those whoare actively engaged in applying digital image processing to the solution of real-worldproblems.Thechancesaregood that you may find some concept or technique which is transferable from some other application to your own area. The book is also highly recommended to those advanced students who contemplate majoring in the area of image processing. Even though it does not qualify as a basic textbook, many fundamental books in imageprocessingare referenced within. Thebook’s preface ends with the statement, ‘We hope that this volume will prove useful as a reference book for working scientists and engineers and as a supplementary textbook for regularand short courses on imageand signal processing.” Surely this aspiration will be realized.

In today’s world of high technology and unprecedented accumulation of knowledge, it is not uncommon to see an area of a wellestablished discipline grow so rapidly that it becomes a major field in itself. This is the case with digital imageprocessing,whichhasemerged from the shadow of the parent field of digital signal processing to take its place among the important specialties of electrical and electronics engineering.Researchand development in digitalimageprocessing has expanded at such a rate that it is virtuallyimpossible for anysingle volume to contain a complete treatment of the subject. Zmge Sequence Analysis focuses on the analysis of image sequences and the application areaswhich benefit from this analysis. As stated by the editor, the purpose of this book is “to survey the rapidly growing field of image sequence analysis and to discuss in depth a number of important selected topics.” The book is composed ofseven chapters which fall into two categories; chapters 2,3, and 7 are comprehensive surveys, whereaschapters 1, 4, 5, and 6 contain individual reports ofspecializedresearch. In chapter 1, several techniques are discussed for estimating twodimensional and threedimensional motion. Included in the discussionare the assumptions and limitations of the various methods, as well as a listing of important applications of motion estimation. Chapter 2 is a thorough review (over 200 pages) of the accessible literature on image sequence analysis with emphasis on practical applications. Oneimmediate consequence of the review is a better understanding of the similaritiesand differences one encounters in the various application areas. Such an understanding may lead to a transfer of solution approaches and techniques from one application area to another. An exhaustive bibliography of over 500 papers is a special treat provided by chapter 2. An author index is also supplied to facilitate the use of this bibliography. Chapter 3 surveys one of the major areas of image processing: image sequence coding. Though restricted to the television signal,the chapter is faithful to the basic goal of image coding, which is to match the output rate of the source to the receiver’s capacity to accept information. The reader is made aware of the different schemes available to reduce the transmission rate. In addition to image sequence coding, another is that ofimagesequence important areaofdigitalimageprocessing enhancement. In chapter 4, the authors present the results of their experiments to reduceimage sequence noiseby motioncompensated temporal fdtering. The different filtering methods are compared, and it is shown that one method mayhave an advantageover another, depen- on the application.

Introduction to Quartz Crystal Unit Design. (Van Nostrand Reinhdd Electrical/Cmputer Science and Engineering Series)-Virgil E. Bottom (New York: NY: Van Nostrand, 1982, 272 pp., bound, $26.50, ISBN 0-442-26201-9).
This book isavowedly tutorial. Those doing research in the field should turn to other sources. The purpose of this book is to help and encourage the beginning engineer to understand the basic principles of piezoelectricity and its applications to the design of quartz crystal units. For this reason, the mathematical derivations aresimplified as much as possible. Complications such as second/order effects are deliberate omitted in order not to obscure the main topic (and not because they are unimportant). Onedimensional systems are used to illustrate basic principles. Anisotropy is sometimes ignored in order to simplify the discussion. The notation is simplified as much as possible in order not to obscure the mainidea. The treatment is limited in scope; many important topics are not treated at all. Among the topics omitted are monolithic filter crystals, tuning fork and other lowfrequency resonators, surface-wavedevices,and most second-order effects. Almost all the book deals with thickness-shear-type resonators such as the ATcut, but the principles developed can, once understood, be extended to much wider applications. Inertial Confinement Fusion-James J. Duderstadt and Gregory A. Moses(New York, N Y : 1982; 347 pp., bound, $48.50, ISBN 0-47109050-6). This text provides engineers, scientists, and advanced undergraduate or graduate students with a broad introduction to inertial confinement fusion. It presents both the fundamental principles underlying the technique, and its application to areassuch as inertial confinement fusion reactors, hybrid fusion-fmion.systems, process heat, andsynthetic fuel production.
