MathematicsMechanization consistsoftheory,softwareandapplicationofc- puterized mathematical activities such as computing, reasoning and discovering. ItsuniquefeaturecanbesuccinctlydescribedasAAA(Algebraization,Algori- mization, Application). The name “Mathematics Mechanization” has its origin in the work of Hao Wang (1960s), one of the pioneers in using computers to do research in mathematics, particularly in automated theorem proving. Since the 1970s, this research direction has been actively pursued and extensively dev- oped by Prof. Wen-tsun Wu and his followers. It di?ers from the closely related disciplines like Computer Mathematics, Symbolic Computation and Automated Reasoning in that its goal is to make algorithmic studies and applications of mathematics the major trend of mathematics development in the information age. The International Workshop on Mathematics Mechanization (IWMM) was initiated by Prof. Wu in 1992, and has ever since been held by the Key L- oratory of Mathematics Mechanization (KLMM) of the Chinese Academy of Sciences. There have been seven workshops of the series up to now. At each workshop, several experts are invited to deliver plenary lectures on cutting-edge methods and algorithms of the selected theme. The workshop is also a forum for people working on related subjects to meet, collaborate and exchange ideas.

This book constitutes the refereed proceedings of the Second International Workshop on Algebraic Frames for the Perception-Action Cycle, AFPAC 2000, held in Kiel, Germany in September 2000.The 20 regular papers presented together with seven invited papers were carefully reviewed and selected for inclusion in the book. Among the topics addressed are action representation analysis, perception-action structure, colorimetry, motion modeling, spatio-temporal structures, geometric transformations, Clifford algebras, geometric algebra, illumination changes, contact modeling, wavelets, adaptive system behaviour, kinematics, hyperharmonic signal analysis, motion estimation, geodesic conturs, etc.

Clifford algebra, then called geometric algebra, was introduced more than a cenetury ago by William K. Clifford, building on work by Grassmann and Hamilton. Clifford or geometric algebra shows strong unifying aspects and turned out in the 1960s to be a most adequate formalism for describing different geometry-related algebraic systems as specializations of one "mother algebra" in various subfields of physics and engineering. Recent work outlines that Clifford algebra provides a universal and powerfull algebraic framework for an elegant and coherent representation of various problems occuring in computer science, signal processing, neural computing, image processing, pattern recognition, computer vision, and robotics. This monograph-like anthology introduces the concepts and framework of Clifford algebra and provides computer scientists, engineers, physicists, and mathematicians with a rich source of examples of how to work with this formalism.

On behalf of the organizerswe would like to welcome all participants to the "Robot Vision 2001" workshop. Our objective has been to bring together - searchersinrobotvision,andtopromoteinteractionanddebate. Participants oftheworkshopcomefromEurope,US,theMiddleEast,theFarEast,andof coursefromNewZealand. Fifty-twopapersweresubmittedtotheworkshop,andeachpaperwasth- oughlyreviewedbyatleastthreereviewers. Seventeenpaperswereselectedfor oral presentation, and seventeen papers were selected for poster presentation. There were no invited technical papers, to give all participants the sense of equalopportunity. Thetechnicalscopeoftheworkshopisverywide,andincludespresentations onmotionanalysis,3Dmeasurements,calibration,navigation,objectrecog- tion,andmore.

The papers are organized in topical sections on PAC systems, low level and early vision, recognition of visual structure, processing of 3D visual space, representation and shape perception, inference and action, and visual and motor neurocomputation.

Die Deutsche Arbeitsgemeinschaft für Mustererkennung veranstaltet seit 1978 jährlich an verschiedenen Orten ein wissenschaftliches Symposium mit dem Ziel, Aufgabenstellungen, Denkweisen und Forschungsergebnisse aus den Gebieten der Mustererkennung vorzustellen, den Erfahrungs- und Ideenaustausch zwischen den Fachleuten anzuregen und den Nachwuchs zu fördern.In dem dieses Jahr erstmals durchgeführten Kontaktforum unter dem Titel "Forum Industrie und Wissenschaft" findet der Austausch von Industrie und Wirtschaft besondere Beachtung.

In 1986, B.K.P. Horn published a book entitled Robot Vision, which actually discussed a wider ?eld of subjects, basically addressing the ?eld of computer vision, but introducing “robot vision” as a technical term. Since then, the - teraction between computer vision and research on mobile systems (often called “robots”, e.g., in an industrial context, but also including vehicles, such as cars, wheelchairs, tower cranes, and so forth) established a diverse area of research, today known as robot vision. Robot vision (or, more general, robotics) is a fast-growing discipline, already taught as a dedicated teaching program at university level. The term “robot vision” addresses any autonomous behavior of a technical system supported by visual sensoric information. While robot vision focusses on the vision process, visual robotics is more directed toward control and automatization. In practice, however, both ?elds strongly interact. Robot Vision 2008 was the second international workshop, counting a 2001 workshop with identical name as the ?rst in this series. Both workshops were organized in close cooperation between researchers from New Zealand and Germany, and took place at The University of Auckland, New Zealand. Participants of the 2008 workshop came from Europe, USA, South America, the Middle East, the Far East, Australia, and of course from New Zealand.
