Pattern Recognition By Humans And Machines 2 Visual Perception

Pattern Recognitions by Humans and Machines, Volume 2: Visual Perceptions covers aspects of research on visual perception. The book discusses visual form perception, figure-ground organization, and the spatial and temporal responses of the visual system; eye movements; and visual pattern perception. The text also describes a computer vision model based on psychophysical experiments; perspectives from brain theory and artificial intelligence; and the capacity to extract shape properties and spatial relations among objects and objects' parts. Knowledge-mediated perception is also considered. Psychologists and people involved in the study of visual perceptions will find the book useful.

The following are the proceedings of the Third International Workshop on Human and Machine Perception held in Pavia, Italy, on September 14 -17, 1998. This edition has been under the auspices of two Institutions: the Cybernetic and Biophysics Group (GNCB) of the Italian National Research Council (CNR), the Centro Interdipartimentale di Scienze Cognitive, of Pavia University and the Centro Interdipartimentale Tecnologie della Conoscenza, of Palermo University. A wide spectrum of topics is covered in this series, ranging from computer perception to psychology and physiology of perception, for analysing and comparing biological and artificial approaches. The theme of this workshop was focused on "Emergence, Attention and Creativity". The workshop structure consisted of five modules each one composed of two invited lectures (dealing with solutions in nature and machines respectively) and a panel discussion. The lectures focused on presenting the state-of-the-art and outlining open questions. In particular, they sought to stress links, suggesting possible synergies between different cultural areas. The panel discussion was conceived as a forum for an open debate, briefly introduced by each panellist, and mainly aimed at deeper investigation for the different approaches and strictly related topics. The panellists were asked to prepare a few statements on hot-points, which were delivered in advance to the participants as a guide for a qualified discussion.

Perspectives in Computing: Human and Machine Vision II compiles papers presented at the second Workshop on Human and Machine Vision held in Montreal, Canada on August 1-3, 1984. This book discusses the perception of transparency in man and machine, human image understanding, and connectionist models and parallelism in high level vision. The theory of the perceived spatial layout of scenes, generative systems of analyzers, and codon constraints on closed 2D shapes are also elaborated. This text likewise covers the environment- and viewer-centered perception of surface orientation, autonomous scene description with range imagery, and pre-attentive processing in vision. This publication is recommended for students and researchers interested in both fields of visual perception and computer vision.

The book provides an up-to-date on machine learning and visual perception, including decision tree, Bayesian learning, support vector machine, AdaBoost, object detection, compressive sensing, deep learning, and reinforcement learning. Both classic and novel algorithms are introduced. With abundant practical examples, it is an essential reference to students, lecturers, professionals, and any interested lay readers.

Examining the current state of the research in perception stressing contributions in visual information processing, this volume provides an original and timely account of recent results obtained in this and other related areas of cognitive psychology. The scope of the book is intended to be broad, featuring state-of-the-art contributions from a number of outstanding researchers from different parts of the world -- the United States, Europe, and Australia. The intention is to update areas of considerable theoretical implications and active experimental investigation in this broad field called the "psychology of perception." This volume's main purpose is to highlight, from a cognitive position, a selected number of important theoretical and empirical topics which deal with critical issues in perception and other high level, related cognitive processes such as attention, mental representation, memory, word naming and semantic categorization. The studies reported were designed to answer many far-reaching questions including: * Is the global precedence effect due to low or high level processing? * Can veridical and illusory perception be explained by the same theory? * What is the relationship between attention and perception? * Is perception "direct" or an inferential process? * What mechanisms are involved in picture and word naming and categorization? * How can word and picture processing be modeled? The answers to these questions seek to unite theoretical perspectives on very important areas of cognitive psychology such as attention, perception, representation of visual objects and words, and human memory.

There is a growing consensus in the human factors/ergonomics community that human factors research has had little impact on significant applied problems. Some have suggested that the problem lies in the fact that much HF/E research has been based on the wrong type of psychology, an information processing view of psychology that is reductionistic and context-free. Ecological psychology offers a viable alternative, presenting a richer view of human behavior that is holistic and contextualized. The papers presented in these two volumes show the conceptual impact that ecological psychology can have on HF/E, as well as presenting a number of specific examples illustrating the ecological approach to human-machine systems. It is the first collection of papers that explicitly draws a connection between these two fields. While work in this area is only just beginning, the evidence available suggests that taking an ecological approach to human factors/ergonomics helps bridge the existing gap between basic research and applied problems.
