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.

Until recently digital processing of biomedical images was conducted solely in the research laboratories of the universities and industry. However, with the advent of computerized tomography in 1972 and the computerized white blood cell differential count in 1974, enormous changes have suddenly occurred. Digital image pro cessing in biomedicine has now become the most active sector in the digital image processing field. Processing rates have reached the level of one trillion picture elements per year in the United States alone and are expected to be ten trillion per year in 1980. This enormous volume of activity has stimulated further re search in biomedical image processing in the last two years with the result that important inroads have been made in applications in radiology, oncology, and ophthalmology. Although much significant work in this field is taking place in Europe, it is in the United States and Japan that the level of activity is highest.

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.

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.

Support for the Conference and the preparation of the Conference papers for publication was provided by the Mathematical Social Sciences Board (MSSB). The MSSB is funded by aNational Science Foundation grant which is administered by the Center for Advanced Study in the Behavioral Sciences as the primary grantee. We are grateful to Hayward Alker, Jr. and William H. Riker of the MSSB for their help and encouragement. The graph shown on the cover is a cognitive map representation of the output from our computer simulation of foreign pOlicy decision-making. We would like to thank Robert Axelrod and Gary Raffel of the University of Michigan for generating the graph. PART I INTRODUCTION 1 CHAPTER 1 THOUGHT AND ACTION IN FOREIGN POLICY G. 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.

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.

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.

In an ever more complex and interrelated world, a better understanding of social systems and of the dynamics of their behavior is of crucial im portance. Many of the tools holding promise of potentially significant contributions to the analysis of social systems have been, or are being developed outside of the social sciences proper, mostly the loose collec tion of diverse scientific approaches called' systems science' or , systems theory' . The editors - all of whom are involved in social systems analysis - have made an attempt in this volume to pull together several aspects of systems science which appear to them to be of particular relevance to the study of social systems: Control systems, stochastic systems, pattern recog nition, fuzzy analysis, simulation, and behavioral models. 29 authors from the disciplines of sociology, social psychology, political science, management science, history, behavioral science, economics, mathematics, engineering, and systems science have contributed to this truly interdis ciplinary effort. All of them have made the attempt to write in a manner understandable by the non-specialist. It is hoped that this volume will be of particular usefulness to students in the social sciences. Most of the articles are too short to provide much more than an initial stimulation. We trust that the references provided by the authors will allow deeper penetration into particular areas.
