Progress in Gestural Interaction contains papers presented at the first Gesture Workshop, which was designed to bring together researchers working on gesture-based interfaces and gestural interaction and to provide a forum for the presentation and exchange of ideas and research currently in progress. It encompassed all aspects of gestural interaction, including:- what are gestures?; appropriateness of gestures used in interfaces; interactional issues; suitable applications; sign-language recognition. Papers are presented from the UK, France, Germany, Italy, USA and Ireland to provide an international viewpoint and the book will be of interest to researchers in the fields of gestural interaction, human-computer interaction, multi-modal interfaces, automatic sign language interpretation and pattern recognition. It could also be a useful supplementary text for courses on multi-modal human-computer interaction.

Computer vision is a rapidly developing and highly interdisciplinary field of computer science and engineering. An increasing number of researchers are turning their attention to the development of vision algorithms that can analyse dynamic images at real-time rates. Real-time vision is needed for automated systems to keep pace with real-world activities and thus control or respond appropriately to them. This is the first book devoted to the subject of real-time computer vision, and includes articles by some of the leading researchers in the world. The focus is on algorithms for interpreting visual input at video rates and on using the gathered information for decision-making and control. Topics covered include: shape recovery; model-based vehicle tracking; active exploration; tracking heads and eyes; controlling robot behavior; visual monitoring; controlling distributed robots. The book will be of interest to students, researchers and engineers involved in the design and programming of visually guided systems.

Die optische Ortsfiltertechnik wird vorrangig zur einkomponentigen (1C) Geschwindigkeits- und Langenbestimmung bei der beruhrungslosen Uberwachung industrieller Prozesse angewendet. Martin Schaeper beschaftigt sich mit der fortfuhrenden Nutzung von flachenhaften, strukturierten Sensoren fur zeitaufgeloste 2D/2C-Messungen, aber auch mit der Implementierung geeigneter Informationsvorverarbeitungen, um eine hohere Abtastung des vorliegenden Prozesses zu erreichen. Ausgehend von der Entstehung des Ortsfiltersignals wird dieses weiterfuhrend als zeitabhangiger Fourier-Koeffizient aufgefasst. Anhand von Hochgeschwindigkeitsbildfolgen stellt der Autor die ortsfilterbasierte Offline-2D/2C-Messung dar. Darauf aufbauend demonstriert er eine echtzeitfahige Erweiterung zur 2D/2C-Geschwindigkeitsmessung anhand eines 4x4-Sensor-Arrays.

It provides insights on how to develop geometry-based methods for 3D shape analysis. The book is an ideal learning resource for graduate students and researchers in computer science, computer engineering and applied mathematics who have an interest in 3D shape analysis, shape motion analysis, image analysis, medical image analysis, computer vision and computer graphics. Due to the rapid advancement of 3D acquisition technologies there has been a big increase in 3D shape data that requires a variety of shape analysis methods, hence the need for this comprehensive resource.

Geometry is a powerful tool to solve a great number of problems in robotics and computer vision. Impressive results have been obtained in these fields in the last decade. It is a new challenge to solve problems of the actual world which require the ability to reason about uncertainty and complex motion constraints by combining geometric, kinematic, and dynamic characteristics. A necessary step is to develop appropriate geometric reasoning techniques with reasonable computational complexity. This volume is based on a workshop held in Grenoble, France, in September 1991. It contains selected contributions on several important areas in the field of robotics and computer vision. The four chapters cover the following areas: - motion planning with kinematic and dynamic constraints, - motion planning and control in the presence of uncertainty, - geometric problems related to visual perception, -numerical problems linked to the implementation of practical algorithms for visual perception.

This book contains the 61 papers that were accepted for presenta tion at the 1992 British Machine Vision Conference. Together they provide a snapshot of current machine vision research throughout the UK in 24 different institutions. There are also several papers from vision groups in the rest of Europe, North America and Australia. At the start of the book is an invited paper from the first keynote speaker, Robert Haralick. The quality of papers submitted to the conference was very high and the programme committee had a hard task selecting around half for presentation at the meeting and inclusion in these proceedings. It is a positive feature of the annual BMV A conference that the entire process from the submission deadline through to the conference itself and publication of the proceedings is completed in under 5 months. My thanks to members of the programme committee for their essential contribution to the success of the conference and to Roger Boyle, Charlie Brown, Nick Efford and Sue Nemes for their excellent local organisation and administration of the conference at the University of Leeds."

Shape detection techniques are an important aspect of computer vision and are used to transform raw image data into the symbolic representations needed for object recognition and location. However, the availability and application of research data relating to shape detection has traditionally been limited by a lack of computational and mathematical skill on the part of the intended end-user. As a result progress in areas such as the automation of visual inspection techniques, where shape detection couls play a pivotal role, has been relatively slow. In this volume, Violet Leavers, an established author and researcher in the field, examines the Hough Transform, a technique which is particularly relevant to industrial applications. By making computational recipes and advice available to the non-specialist, the book aims to popularize the technique, and to provide a bridge between low level computer vision tasks and specialist applications. In addition, Shape Detection in Computer Vision Using the Hough Transform assesses practical and theoretical issues which were previously only available in scientific literature in a way which is easily accessible to the non-specialist user. Shape Detection in Computer Vision Using the Hough Transform fills an obvious gap in the existing market. It is an important textbook which will provide postgraduate students with a thorough grounding in the field, and will also be of interest to junior research staff and program designers.
