Bildverstehen, Bilder und die ihnen zugrundeliegenden Szenen mit den darin vorkommenden Objekten verstehen und beschreiben, das bedeutet aus der Sicht der Informatik: Sehen mit dem Computer - ‘Computer Vision’. Das Buch behandelt neben wichtigen Merkmalen des menschlichen visuellen Systems auch die nötigen Grundlagen aus digitaler Bildverarbeitung und aus künstlicher Intelligenz. Im Zentrum steht die schrittweise Entwicklung eines neuen Systemmodells für Bildverstehen, anhand dessen verschiedene "Abstraktionsebenen" des maschinellen Sehens, wie Segmentation, Gruppierung auf Aufbau einer Szenenbeschreibung besprochen werden. Das Buch bietet außerdem einen Überblick über gegenwärtige Trends in der Forschung sowie eine sehr aktuelle und ausführliche Bibliographie dieses Fachgebietes. Es liegt hiermit erstmalig eine abgeschlossene, systematische Darstellung dieses noch jungen und in dynamischer Entwicklung begriffenen Fachgebietes vor.

Flame Hardening

Author: Hans Wilhelm Grönegress

Publisher: Springer Science & Business Media

ISBN: 3642867219

Category: Technology & Engineering

Page: 64

View: 7875

This book intended for shop use tries to familiarize the reader with the peculiari ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.

With the ongoing release of 3D movies and the emergence of 3D TVs, 3D imaging technologies have penetrated our daily lives. Yet choosing from the numerous 3D vision methods available can be frustrating for scientists and engineers, especially without a comprehensive resource to consult. Filling this gap, Handbook of 3D Machine Vision: Optical Metrology and Imaging gives an extensive, in-depth look at the most popular 3D imaging techniques. It focuses on noninvasive, noncontact optical methods (optical metrology and imaging). The handbook begins with the well-studied method of stereo vision and explains how random speckle patterns or space-time varying patterns substantially improve the results of stereo vision. It then discusses stereo particle image velocimetry as a major experimental means in fluid dynamics, the robust and easy-to-implement structured-light technique for computer science applications, digital holography for performing micro- to nanoscale measurements, and grating, interferometry, and fringe projection techniques for precisely measuring dynamically deformable natural objects. The book goes on to describe techniques that do not require triangulation to recover a 3D shape, including time-of-flight techniques and uniaxial 3D shape measurement, as well as 3D measurement techniques that are not restricted to surface capture, such as 3D ultrasound, optical coherence tomography, and 3D endoscopy. The book also explores how novel 3D imaging techniques are being applied in the promising field of biometrics—which may prove essential to security and public safety. Written by key players in the field and inventors of important imaging technologies, this authoritative, state-of-the-art handbook helps you understand the core of 3D imaging technology and choose the proper 3D imaging technique for your needs. For each technique, the book provides its mathematical foundations, summarizes its successful applications, and discusses its limitations.

Robots and Lattice Automata

Author: Georgios Ch. Sirakoulis,Andrew Adamatzky

Publisher: Springer

ISBN: 3319109243

Category: Technology & Engineering

Page: 313

View: 5096

The book gives a comprehensive overview of the state-of-the-art research and engineering in theory and application of Lattice Automata in design and control of autonomous Robots. Automata and robots share the same notional meaning. Automata (originated from the latinization of the Greek word “αυτόματον”) as self-operating autonomous machines invented from ancient years can be easily considered the first steps of robotic-like efforts. Automata are mathematical models of Robots and also they are integral parts of robotic control systems. A Lattice Automaton is a regular array or a collective of finite state machines, or automata. The Automata update their states by the same rules depending on states of their immediate neighbours. In the context of this book, Lattice Automata are used in developing modular reconfigurable robotic systems, path planning and map exploration for robots, as robot controllers, synchronisation of robot collectives, robot vision, parallel robotic actuators. All chapters are written in an accessible manner and lavishly illustrated. The book will help computer and robotic scientists and engineers to understand mechanisms of decentralised functioning of robotic collectives and to design future and emergent reconfigurable, parallel and distributed robotic systems.

Die Stadt des Affengottes

Eine unbekannte Zivilisation, ein mysteriöser Fluch, eine wahre Geschichte

Eine wahre Indiana-Jones-Geschichte - eine archäologische Sensation Schon seit dem 16. Jahrhundert gab es Gerüchte über eine Provinz im Regenwald von Honduras, deren Städte reich und prachtvoll seien, ganz besonders die Weiße Stadt, auch Stadt des Affengottes genannt. Immer wieder machten sich Abenteurer und Archäologen auf die Suche nach den Zeugnissen dieser Zivilisation, die offenbar nicht zu den Mayas gehörte. Manchmal stießen sie tatsächlich auf Ruinen, aber eine wirkliche Erforschung war in dem von giftigen Schlangen und tödlichen Krankheitserregern verseuchten und vom Dschungel überwucherten Gelände unmöglich. Erst die moderne Lasertechnik, mit deren Hilfe das Gelände aus der Luft gescannt wird, ermöglichte genauere Hinweise, wo sich größere Ansiedlungen befinden. Um sie vor Ort zu untersuchen muss man sich allerdings auch heute noch auf den beschwerlichen Weg durch den Dschungel machen. Der Schriftsteller und Journalist Douglas Preston schloss sich kürzlich einer archäologischen Expedition an. Sie fand tatsächlich die eindrucksvollen Ruinen einer untergegangenen Stadt, aber sie zahlte am Ende auch einen hohen Preis.
