The book constitutes the refereed proceedings of the International Workshop on Algebraic Frames for the Perception-Action Cycle, AFPAC '97, held in Kiel, Germany, in September 1997.
The volume presents 12 revised full papers carefully reviewed and selected for inclusion in the book. Also included are 10 full invited papers by leading researchers in the area providing a representative state-of-the-art assessment of this rapidly growing field. 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.

This book constitutes the refereed proceedings of the First International Conference on Scale-Space Theory for Computer Vision, Scale-Space '97, held in Utrecht, The Netherlands, in July 1997.
The volume presents 21 revised full papers selected from a total of 41 submissions. Also included are 2 invited papers and 13 poster presentations. This book is the first comprehensive documentation of the application of Scale-Space techniques in computer vision and, in the broader context, in image processing and pattern recognition.

A comprehensive introduction to colorimetry from a conceptual perspective. Color for the Sciences is the first book on colorimetry to offer an account that emphasizes conceptual and formal issues rather than applications. Jan Koenderink's introductory text treats colorimetry-literally, "color measurement"-as a science, freeing the topic from the usual fixation on conventional praxis and how to get the "right" result. Readers of Color for the Sciences will learn to rethink concepts from the roots in order to reach a broader, conceptual understanding. After a brief account of the history of the discipline (beginning with Isaac Newton) and a chapter titled "Colorimetry for Dummies," the heart of the book covers the main topics in colorimetry, including the space of beams, achromatic beams, edge colors, optimum colors, color atlases, and spectra. Other chapters cover more specialized topics, including implementations, metrics pioneered by Schroedinger and Helmholtz, and extended color space. Color for the Sciences can be used as a reference for professionals or in a formal introductory course on colorimetry. It will be especially useful both for those working with color in a scientific or engineering context who find the standard texts lacking and for professionals and students in image engineering, computer graphics, and computer science. Each chapter ends with exercises, many of which are open-ended, suggesting ways to explore the topic further, and can be developed into research projects. The text and notes contain numerous suggestions for demonstration experiments and individual explorations. The book is self-contained, with formal methods explained in appendixes when necessary.

This book presents an analysis of limits in perception from the vantage point of the physicist, the engineer, the psychophysicist, the psychologist and the theorist. Limits in perception find their causal explanation at many logically and/or physically different levels. Some of the most fundamental bottlenecks are due to the quantum mechanical and atomistic structure of the microworld. Other simple constraints are due to the material constitution of sensory organs. For instance, the fact that the eye is predominantly composed of water limits both the optical quality and the available spectral window. The engineer uses knowledge on such limits to design equipment that optimizes human performance in daily life. Examples include room acoustics and visual displays. Psychophysicists and psychologists deal with limits on a quite different logical level. These limits constrain much of our perceptually guided behaviour. The book includes chapters on such topics as movement perception, binocular vision, illusory phenomena, language and perception, the perception of time. A few concluding chapters on fundamental limits imposed by information theoretical constraints on the coding and representation of sensed structure are included. Limits in Perception will be important reading material for scientists and/or engineers in the following fields: perception, experimental psychology, sensory biology, physics, neuroscience, human engineering, artificial intelligence, robotics, ophthalmology, audiology, psychonomics and ergonomics, remote sensing.
