Available in PDF, EPUB and Kindle. Book excerpt: 1.1 Statement of the Problem This work describes a new and effective computer algorithm for detecting the contours of ribs in ehest radiographs. The problem, which is common to both the research areas of Machine Vision and Biomedical Computing, is to extract graphical information, such as that represented in Figure 1-lb, from a picture such as Figure 1-la. Figure 1-la shows a typical posterior-anterior (PA) ehest radiograph while Figure 1-lb shows a drawing of the ventral aspect of the thorax. lt is hoped that this researchwill contribute significantly toward developing an automated system for interpreting ehest radio graphs. 1.2 Why Have We Carried Out This Research? Since about one-third of the 650,000,000 medical radiographs (X-ray photographs) taken annually in the United States areehest radiographs, there is a growing awareness of the need for a computer aided system to help diagnose these radiographs. The detection of rib contours is, of course, a necessary element in such a system. In addition to being able to accommodate the need for a mass screening program, an automated systemalso has the ability to detect anomalies at earlier stages. Ziskin et al (1971) state that reliable 2 {a) Original Chest Radiograph Figure 1-1.

Available in PDF, EPUB and Kindle. Book excerpt: This popular guide to the examination and interpretation of chest radiographs is an invaluable aid for medical students, junior doctors, nurses, physiotherapists and radiographers. Translated into over a dozen languages, this book has been widely praised for making interpretation of the chest X-ray as simple as possible The chest X-ray is often central to the diagnosis and management of a patient. As a result every doctor requires a thorough understanding of the common radiological problems. This pocketbook describes the range of conditions likely to be encountered on the wards and guides the reader through the diagnostic process based on the appearance of the abnormality shown. Covers the full range of common radiological problems. Includes valuable advice on how to examine an X-ray. Assists the doctor in determining the nature of the abnormality. Points the clinician towards a possible differential diagnosis. A larger page size allows for larger and clearer illustrations. A new chapter on the sick patient covers the patient on ITU and the appearance of lines and tubes. There is extended use of CT imaging with advice on choosing modalities depending on the clinical circumstances. A new section of chest x-ray problems incorporates particularly challenging case histories. The international relevance of the text has been expanded with additional text and images.
Download or read book Computer recognition of human faces written by KANADE and published by Birkhäuser. This book was released on 2013-12-01 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Picture processing by computer has found its application in various fields. Character recognition has shown the most practical success. Furthermore, the techniques span much more sophisticated applications such as interpretation of biomedical images and X-ray films, measurement of images in nuclear physics, processing of a large volume of pictorial data sent from the satellites, etc. The particular problem attacked in this thesis is computer analysis and identification of human faces. Pictures of human faces are successfully analyzed by a computer program which extracts face feature points, such as nose, mouth, eyes, and so on. The program was tested with more than 800 photographs The research has been done with main emphasis on the method of how to incorporate the picture structures into the picture anlysis program. The success of the program is due to the employment of a flexible picture analysis scheme with feedbacks, which will be described in the next chapter. An experiment on face identification of 20 people was also conducted. I-1. Picture Analysis and Recognition- New Aspects When shown the pictures of the human face of Fig. 1-1, we can immediately tell the positions of the nose, mouth and eyes; and more- over, we can say that both pictures surely portray the same person. Picture analysis and recognition by computer concerns itself with this type of two-dimensional image processing. In this thesis, I selected human-face pictures as objects of processing.

Available in PDF, EPUB and Kindle. Book excerpt: The role of the computer in the practice of organic chemistry has been firmly established over the past decade. Its uses as a large scale information storage and retrieval device in chemistry have been too numerous to mention. More recently, the applicability of computers to the problem of discovering valid and reasonable synthesis routes for organic molecules has been demonstrated. This has been both as an adjunct to the 1 chemist in the on-line interactive mode ,2,3 and also as a wholly computer-directed system seeking to simulate the intelligent prob- 4 lem-solving activity of the human organic synthetic chemist. ,5 In all of these computer applications to organic chemistry, it has been necessary to devise some computer-compatible repres- tation of an organic molecule that is both canonical and c- venient for table look-ups. This is in order that entities that have been constructed at different times under different circumstances can be identified and classified, with identical molecules being recognized as such even if their connection matrices list the elements of the molecule in different orders.

This book was released on 2013-12-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: 0.1 Gaps in Optimizing A comparison of the levels of development of Operations Research, Simulation Technique and Optimal Control Theory appears to gain increasing interest. Operations Research Sciences achieved very high mathematical standards and solved a great amount of important optimization problems, mainly at the level of management of private corporation and civil or military government tasks, however, these achievements are seldom incorporated in the mathematical curriculum of modern universities. Nevertheless, Operations Research seems to have failed in solving long range or strategical problems as they arise in any broader social, economical or political context (MUller-Merbach, 1976). Also for the weakest task, namely that of improving theory building, system simulation works as an optimization tool. Simulation models of large complex systems, like socio economical or political ones, failed until now to fit large empirical data bases. This was, in fact, one of the few serious objections against the form in which Forrester solved some problems modelling and simulating urban and world de velopments (Forrester, 1969; Forrester, 1971; IEEE-SCC October 197o; IEEE-SMC April 1972; Mass, 1974; Schroeder, 1975).

Available in PDF, EPUB and Kindle. Book excerpt: This book is a presentation of my recent research work into the theory and applications of mathematical relations between finite sets. The consequent results and concepts are expressed in 'conjunction' with the idea of a union of simplicial complexes and the algorithms and overall methodology have become known as Q-Analysis. The mathematical ideas are essentially comhinatorial and are developed in Section-A of the book, whilst Section-R contains an application to a community study (that of the IJniversity of Rssex). All of the work has been published elsewhere, in the usual form of papers, and a comprehensive introduction to the whole approach will be found in my earlier book, Mathematical Structure in Human Affairs (Heinemann, London 1974). Much of the research work referred to in this present hook would not have been possible without the co-operation of my research team, of whom I would particularly like to thank J.II. Johnson, and its puhlication owes a lot to the secretarial help provided by ~Iary Low. R.H. Atkin IJniversity of Rssex U.K.

MATTHEW BONHAM The American University MICHAEL J. SHAPIRO University of Hawaii Introduction The papers assembled here constitute, and to some extent represent, widely disparate views of foreign policy thinking and decision-making. As is the case with almost any collective enterprise, it is possible to suggest some noteworthy resemblances among the contributions to this volume and to indicate grounds for distinguishing them from other "approaches.
Download or read book Innovation Economic Change and Technology Policies written by STROETMANN and published by Birkhäuser. This book was released on 2013-11-11 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technological progress is a major factor chaping economic growth. Today's standard of living is a direct result of scientific advances and technical change in the past. Since uncontrolled technological progress has become amenace to our well being and may actually threat our survival, it is necessary to learn to manage technological progress and direct innovative activities in such a manner that both private wants and social needs playa dominant role in determining the rate and direction of technical change. This requires a better understanding of the processes of technical change, of their impact on and interrelationships with economic and social developments and of the means and measures by which both individuals and governments can influence and direct technological progress. To this end, the Ninistry for Research and Technology of the Federal Republ ic of Germany and the National Science Foundation of the Uni ted States of America invited a group of scholars, corporate managers and civil servants to a one week seminar on "Technolo gical Innovation". The seminar took place in April, 1976, in Bonn, Federal Republ ic of Germany. Most papers presented at this meeting were specifically prepared for the seminar. With this volume, they are made available to a larger audience to further stimulate discussion not only among scholars interested in innovation research and technology policy questions but also among managers, union officials, civil ser vants and others directly or indirectly concerned with and affected by technical change.

Download or read book Chest Imaging written by Les R. Folio and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chest X-ray (CXR) or chest radiograph remains the most commonly ordered imaging study in medicine, yet paradoxically is often the most complex to learn, recall, and master effective and accurate interpretation. The chest radiograph includes all thoracic anatomy and provides a high yield, given the low cost and single source. This guide presents a structured lexicon for use by readers to reproducibly describe radiographic abnormalities of the chest detected on plain film CXRs. The lexicon is designed to provide readers with clinically significant differentiation of abnormalities detected. The content is structured to relate specific combinations of distinct radiographic findings to classes/groupings of pathological etiologies of those findings. Recognizing the individual findings and identifying their combination or lack of combination with other individual findings allows readers to create effective differential diagnoses that can then be further evaluated using other imaging procedures and/or non-radiographic clinical information. The book includes hundreds of images, including radiographs, CTs, graphics, and analogous models to help teach otherwise complex processes and radiographic principles.
Download or read book Advances in Digital Image Processing written by P. Stucki and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital image processing, originally established to analyze and improve lunar images, is rapidly growing into a wealth of new appli cations, due to the enormous technical progress made in computer engineering. At present, the most important fields of growth appear to emerge in the areas of medical image processing (i. e. tomography, thermography), earth resource inventory (i. e. land usage, minerals), office automation (i. e. document storage, retrieval and reproduction) and industrial production (i. e. computer vision for mechanical ro bots). Currently, emphasis is being shifted from signal-processing re search and design-innovation activities towards cost-efficient system implementations for interactive digital image processing. For the years ahead, trends in computer engineering indicate still further advances in Large Scale Integration (LSI) and Input/Output (I/O) technologies allowing the implementation of powerful parallel and/or distributed processor architectures for real-time processing of high resolution achromatic and color images. In view of the many new developments in the field of digital image processing and recognizing the importance of discussing these developments amongst key scientists that might make use of them, ffiM Germany sponsored an international symposium on 'Advances in Digital Image Processing', held at Bad Neuenahr, Federal Republic of Germany, September 26 - 28, 1978. The interest shown in this symposium encouraged the publi cation of the papers presented in this volume of the ffiM Research Symposium Series.
Download or read book Computer Vision Systems written by Allen Hanson and published by Elsevier. This book was released on 1978-01-01 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer Vision Systems is a collection of papers presented at the Workshop on Computer Vision Systems held at the University of Massachusetts in Amherst, Massachusetts, on June 1-3, 1977. Contributors discuss the breadth of problems that must be taken into account in the development of general computer vision systems. Topics covered include the application of system engineering techniques to the design of artificial intelligence systems; representation and segmentation of natural scenes; and pragmatic aspects of machine vision. Psychophysical measures of representation and interpretation are also considered. This monograph is divided into four sections: Issues and Research Strategies, Segmentation, Theory and Psychology, and Systems. The first chapter explores the problem of recovering the intrinsic characteristics of scenes from images, along with its implications for machine and human vision. The discussion then turns to special-purpose low-level vision systems that can be flexibly reconfigured as the need arises; design, development, and implementation of large systems from the human engineering point of view; and representation of visual information. The next section examines hierarchical relaxation for waveform parsing; the topology and semantics of intensity arrays; and visual images as spatial representations in active memory. The use of edge cues to recognize real-world objects is also analyzed. This text will be a useful resource for systems designers, computer engineers, and scientists as well as psychologists.
