| color constancy in psychology: Perceptual Constancy Vincent Walsh, Janusz Kulikowski, 1998-08-13 The world is not always truly reflected in what we see. The brain creates images, fills in gaps and even at times constructs fictions. This book brings together experts from several diverse fields to present state of the art accounts of how the visual world enters two small holes in our heads and is reconstructed to give us the rich impressions of color, movement, and shape. |
| color constancy in psychology: Color Constancy Marc Ebner, 2007-06-05 A human observer is able to recognize the color of objects irrespective of the light used to illuminate them. This is called color constancy. A digital camera uses a sensor to measure the reflected light, meaning that the measured color at each pixel varies according to the color of the illuminant. Therefore, the resulting colors may not be the same as the colors that were perceived by the observer. Obtaining color constant descriptors from image pixels is not only important for digital photography, but also valuable for computer vision, color-based automatic object recognition, and color image processing in general. This book provides a comprehensive introduction to the field of color constancy, describing all the major color constancy algorithms, as well as presenting cutting edge research in the area of color image processing. Beginning with an in-depth look at the human visual system, Ebner goes on to: examine the theory of color image formation, color reproduction and different color spaces; discuss algorithms for color constancy under both uniform and non-uniform illuminants; describe methods for shadow removal and shadow attenuation in digital images; evaluate the various algorithms for object recognition and color constancy and compare this to data obtained from experimental psychology; set out the different algorithms as pseudo code in an appendix at the end of the book. Color Constancy is an ideal reference for practising engineers, computer scientists and researchers working in the area of digital color image processing. It may also be useful for biologists or scientists in general who are interested in computational theories of the visual brain and bio-inspired engineering systems. |
| color constancy in psychology: Encyclopedia of Color Science and Technology , 2016-05-08 The Encyclopedia of Color Science and Technology provides an authoritative single source for understanding and applying the concepts of color to all fields of science and technology, including artistic and historical aspects of color. Many topics are discussed in this timely reference, including an introduction to the science of color, and entries on the physics, chemistry and perception of color. Color is described as it relates to optical phenomena of color and continues on through colorants and materials used to modulate color and also to human vision of color. The measurement of color is provided as is colorimetry, color spaces, color difference metrics, color appearance models, color order systems and cognitive color. Other topics discussed include industrial color, color imaging, capturing color, displaying color and printing color. Descriptions of color encodings, color management, processing color and applications relating to color synthesis for computer graphics are included in this work. The Encyclopedia also delves into color as it applies to other domains such as art and design – ie – color design, color harmony, color palettes, color and accessibility, researching color deficiency, and color and data visualization. There is also information on color in art conservation, color and architecture, color and educations, color and culture, and an overview of the history of color and comments on the future of color. This unique work will extend the influence of color to a much wider audience than has been possible to date. |
| color constancy in psychology: Colour and Form Perception: Straddling the Boundary Galina V. Paramei, Cees van Leeuwen, 2016-05-31 Starting from psychophysics, over the last 50 years, most progress in unravelling the mechanisms of color vision has been made through the study of single cell responses, mainly in LGN and striate cortex. A similar development in the study of form perception may seem to be underway, centred on the study of temporal cortex. However, because of the combinatorial characteristics of form perception, we are also observing the opposite tendency: from single-cell activity to population coding, and from static receptive field structures to system dynamics and integration and, ultimately, a synthetic form of psychophysics of color and form perception. From single cells to system integration: it is this development the present Research Topic wishes to highlight and promote. How does this development affect our views on the various attributes of perception? In particular, we are interested in to what extent evolving knowledge in the field of color perception is relevant within a developing integrative framework of form perception. The goal of this Research Topic is to bring together experimental research encompassing both color and form perception. For this volume, we planned a broad scope of topics – on color in complex scenes, color and form, as well as dynamic aspects of form perception. We expect that the Research Topic will be attractive to the community of researchers whose work straddles the boundary between the two visual perception fields, as well as to the wider community interested in integrative/systems neuroscience. |

| color constancy in psychology: Handbook of Color Psychology Andrew J. Elliot, Mark D. Fairchild, Anna Franklin, 2015-12-17 We perceive color everywhere and on everything that we encounter in daily life. Color science has progressed to the point where a great deal is known about the mechanics, evolution, and development of color vision, but less is known about the relation between color vision and psychology. However, color psychology is now a burgeoning, exciting area and this Handbook provides comprehensive coverage of emerging theory and research. Top scholars in the field provide rigorous overviews of work on color categorization, color symbolism and association, color preference, reciprocal relations between color perception and psychological functioning, and variations and deficiencies in color perception. The Handbook of Color Psychology seeks to facilitate cross-fertilization among researchers, both within and across disciplines and areas of research, and is an essential resource for anyone interested in color psychology in both theoretical and applied areas of study. |
| color constancy in psychology: Colour Perception Rainer Mausfeld, Dieter Heyer, 2003-11-06 Colour has long been a source of fascination to both scientists and philosophers. In one sense, colours are in the mind of the beholder, in another sense they belong to the external world. Colours appear to lie on the boundary where we have divided the world into 'objective' and 'subjective' events. They represent, more than any other attribute of our visual experience, a place where both physical and mental properties are interwoven in an intimate and enigmatic way. The last few decades have brought fascinating changes in the way that we think about 'colour' and the role 'colour' plays in our perceptual architecture. In Colour Perception: Mind and the physical world, leading scholars from cognitive psychology, philosophy, neurophysiology, and computational vision provide an overview of the contemporary developments in our understanding of colours and of the relationship between the 'mental' and the 'physical'. With each chapter followed by critical commentaries, the volume presents a lively and accessible picture of the intellectual traditions which have shaped research into colour perception. Written in a non-technical style and accessible to an interdisciplinary audience, the book will provide an invaluable resource for researchers in colour perception and the cognitive sciences. |
| color constancy in psychology: Visual Psychophysics Zhong-Lin Lu, Barbara Dosher, 2013-10-11 A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science. |

| color constancy in psychology: Neurobiology Franco Conti, Vincent Torre, 2012-12-06 Understanding how the brain works is undoubtedly the greatest challenge for human intelligence and one of the most ambitious goals of contemporary science. We are certainly far from this goal, but significant advancements in several fields of Neuroscience and Neurobiology are being obtained at an increasing pace. The NATO ASI School in Neurobiology, held in Erice May 2-12,1995, as the 23rd Course of the International School of Biophysics, provided an update on three basic topics: Biophysics and Molecular Biology ofIon Channels, Sensory Transduction, and Higher Order Functions. Current knowledge on these subjects was covered by formal lectures and critical discussions between lecturers and participants. This book collects original contributions from those scientists who attended the School. Many students presented their results in poster sessions, steering lively informal discussions. A selection of these contributions is also included. A major portion of the program of the School was devoted to a general overview of current trends of thought and experimental approaches in neurobiology, emphasising the importance of understanding molecular aspects of the elementary events underlying sensory transduction and processing in the nervous system, without indulging however in a pure reductionistic view of such complex phenomena. Recent studies of molecular biology and the electrophysiology of heterologously expressed ionic channels, have shed new light on the molecular mechanisms underlying ionic permeation of excitable membranes and its regulation by physical and chemical parameters. |

| color constancy in psychology: Color for Science, Art and Technology Kurt Nassau, 1997-12-18 The aim of this book is to assemble a series of chapters, written by experts in their fields, covering the basics of color - and then some more. In this way, readers are supplied with almost anything they want to know about color outside their own area of expertise. Thus, the color measurement expert, as well as the general reader, can find here information on the perception, causes, and uses of color. For the artist there are details on the causes, measurement, perception, and reproduction of color. Within each chapter, authors were requested to indicate directions of future efforts, where applicable. One might reasonably expect that all would have been learned about color in the more than three hundred years since Newton established the fundamentals of color science. This is not true because:• the measurement of color still has unresolved complexities (Chapter 2)• many of the fine details of color vision remain unknown (Chapter 3)• every few decades a new movement in art discovers original ways to use new pigments, and dyes continue to be discovered (Chapter 5)• the philosophical approach to color has not yet crystallized (Chapter 7)• new pigments and dyes continue to be discovered (Chapters 10 and 11)• the study of the biological and therapeutic effects of color is still in its infancy (Chapter 2).Color continues to develop towards maturity and the editor believes that there is much common ground between the sciences and the arts and that color is a major connecting bridge. |
| color constancy in psychology: Cognition Through Color Jules B. Davidoff, 1991 A century ago phrenologists described a bump for color located just over the eyebrow. Today's modular approach to the organization of the visual cortex is more sophisticated, yet it still holds that there are brain areas dedicated solely to particular aspects of perception. Cognition through Color reviews the current status of investigations of color cognition from the standpoint of modern neuropsychology. It provides clear evidence, based on a large body of empirical study that includes the author's own work on color perception and naming, that color appears to be one of the basic building blocks or modules from which perception is constructed and our memories organized. Davidoff systematically relates this evidence to an explicit model of color cognition from sensation through functional role to naming.The original impetus for Cognition through Color came from the investigation of individuals with brain damage. There are, for example, patients who have difficulty in naming colors. More important, despite normal color vision, memory for colors can be split off from all aspects of memory for shapes and objects, providing a strong case for the notion of modularity in vision.Davidoff shows that to understand how color is remembered, we must know how objects are recognized. He observes that the perception of what we call color is, in essence, the study of the surface properties of objects, and he develops a model in which the mental representations for color can be linked to the knowledge of objects. Throughout he emphasizes detailed critical analysis of experimental data in light of current theories of both perception and cognition. |
| color constancy in psychology: Perceptual Organization Michael Kubovy, James R. Pomerantz, 2017-03-31 Originally published in 1981, perceptual organization had been synonymous with Gestalt psychology, and Gestalt psychology had fallen into disrepute. In the heyday of Behaviorism, the few cognitive psychologists of the time pursued Gestalt phenomena. But in 1981, Cognitive Psychology was married to Information Processing. (Some would say that it was a marriage of convenience.) After the wedding, Cognitive Psychology had come to look like a theoretically wrinkled Behaviorism; very few of the mainstream topics of Cognitive Psychology made explicit contact with Gestalt phenomena. In the background, Cognition's first love – Gestalt – was pining to regain favor. The cognitive psychologists' desire for a phenomenological and intellectual interaction with Gestalt psychology did not manifest itself in their publications, but it did surface often enough at the Psychonomic Society meeting in 1976 for them to remark upon it in one of their conversations. This book, then, is the product of the editors’ curiosity about the status of ideas at the time, first proposed by Gestalt psychologists. For two days in November 1977, they held an exhilarating symposium that was attended by some 20 people, not all of whom are represented in this volume. At the end of our symposium it was agreed that they would try, in contributions to this volume, to convey the speculative and metatheoretical ground of their research in addition to the solid data and carefully wrought theories that are the figure of their research. |
| color constancy in psychology: The Routledge Handbook of Philosophy of Colour Derek H. Brown, Fiona Macpherson, 2020-09-27 From David Hume’s famous puzzle about the missing shade of blue, to current research into the science of colour, the topic of colour is an incredibly fertile region of study and debate, cutting across philosophy of mind, epistemology, metaphysics, and aesthetics, as well as psychology. Debates about the nature of our experience of colour and the nature of colour itself are central to contemporary discussion and argument in philosophy of mind and psychology, and philosophy of perception. This outstanding Handbook contains 29 specially commissioned contributions by leading philosophers and examines the most important aspects of philosophy of colour. It is organized into six parts: The Importance of Colour to Philosophy The Science and Spaces of Colour Colour Phenomena Colour Ontology Colour Experience and Epistemology Language, Categories, and Thought. The Routledge Handbook of Philosophy of Colour is essential reading for students and researchers in philosophy of mind and psychology, epistemology, metaphysics, and aesthetics, as well as for those interested in conceptual issues in the psychology of colour. |
| color constancy in psychology: Perception and Cognition Gary Carl Hatfield, 2009 How do we see? This question has fascinated and perplexed philosophers and scientists for millennia. In visual perception, mind and world meet, when light reflected from objects enters the eyes and stimulates the nerves leading to activity in the brain near the back of the head. This neural activity yields conscious experiences of a world in three dimensions, clothed in colors, and immediately recognized as (say) ground, sky, grass, trees, and friends. The visual brain also produces nonconscious representations that interact with other brain systems for perception and cognition and that help to regulate our visually guided actions. But how does all of this really work? The answers concern the physiology, psychology, and philosophy of visual perception and cognition. Gary Hatfield's essays address fundamental questions concerning, in Part I, the psychological processes underlying spatial perception and perception of objects; in Part II, psychological theories and metaphysical controversies about color perception and qualia; and, in Part III, the history and philosophy of theories of vision, including methodological controversies surrounding introspection and involving the relations between psychology and the fields of neuroscience and cognitive science. An introductory chapter provides a unified overview; an extensive reference list rounds out the volume. |
| color constancy in psychology: Introduction to Psychology Jennifer Walinga, Charles Stangor, This book is designed to help students organize their thinking about psychology at a conceptual level.

The beginning of each section includes learning objectives; throughout the body of each section are key terms in bold followed by their definitions in italics; key takeaways, and exercises and critical thinking activities end each section. |
| color constancy in psychology: The New Visual Neurosciences John S. Werner, Leo M. Chalupa, 2013-10-25 A comprehensive review of contemporary research in the vision sciences, reflecting the rapid advances of recent years. Visual science is the model system for neuroscience, its findings relevant to all other areas. This essential reference to contemporary visual neuroscience covers the extraordinary range of the field today, from molecules and cell assemblies to systems and therapies. It provides a state-of-the art companion to the earlier book The Visual Neurosciences (MIT Press, 2003). This volume covers the dramatic advances made in the last decade, offering new topics, new authors, and new chapters. The New Visual Neurosciences assembles groundbreaking research, written by international authorities. Many of the 112 chapters treat seminal topics not included in the earlier book. These new topics include retinal feature detection; cortical connectomics; new approaches to mid-level vision and spatiotemporal perception; the latest understanding of how multimodal integration contributes to visual perception; new theoretical work on the role of neural oscillations in information processing; and new molecular and genetic techniques for understanding visual system development. An entirely new section covers invertebrate vision, reflecting the importance of this research in understanding fundamental principles of visual processing. Another new section treats translational visual neuroscience, covering recent progress in novel treatment modalities for optic nerve disorders, macular degeneration, and retinal cell replacement. The New Visual Neurosciences is an indispensable reference for students, teachers, researchers, clinicians, and anyone interested in contemporary neuroscience.

| color constancy in psychology: Seeing Black and White Alan Gilchrist, 2006-06-08 How the human visual system determines the lightness of a surface, that is, its whiteness, blackness, or grayness, remains--like vision in general--a mystery. In fact, we have not even been able to create a machine that can determine, through an artificial vision system, whether an object is white, black, or gray. Although the photoreceptors in the eye are driven by light, the light reflected by a surface does not reveal its shade of gray. Depending upon the level of illumination, a surface of any shade of gray can reflect any amount of light. In Seeing Black and White Alan Gilchrist ties together over 30 years of his own research on lightness, and presents the first comprehensive, historical review of empirical work on lightness, covering the past 150 years of research on images ranging from the simple to the complex. He also describes and analyzes the many theories of lightness--including his own--showing what each can and cannot explain. Gilchrist highlights the forgotten-yet-exciting work done in the first third of the twentieth century, describing several crucial experiments and examining the brilliant but nearly unknown work of the Hungarian gestalt theorist, Lajos Kardos. Gilchrists review also includes a survey of the pattern of lightness errors made by humans, many of which result in delightful illusions. He argues that because these errors are not random, but systematic, they are the signature of our visual software, and so provide a powerful tool that can reveal how lightness is computed. Based on this argument and the concepts of anchoring, grouping, and frames of reference, Gilchrist presents a new theoretical framework that explains an unprecedented array of lightness errors. As both the first comprehensive overview of research on lightness and the first unified presentation of Gilchrists new theoretical framework Seeing Black and White will be an invaluable resource for vision scientists, cognitive psychologists, and cognitive neuroscientists. |

| color constancy in psychology: Deviate Beau Lotto, 2017-04-27 World-renowned neuroscientist Beau Lotto reveals the truths of human perception and devises a cognitive toolkit for how to succeed in a world of uncertainty. Perception is the foundation of human experience, but few of us understand how our own perception works. By revealing the startling truths about the brain and perception, Beau Lotto shows that the next big innovation is not a new technology: it is a new way of seeing. In his first major book, Beau Lotto draws on over a decade of pioneering research to show how our brains play tricks on us. With an innovative combination of case studies and optical- and perception-illusion exercises, DEVIATE will revolutionise the way you see the world. With this new understanding of how the brain works and its perceptive trickery, we can apply these insights to every aspect of life and work. DEVIATE is not just an engaging look into the neuroscience of thought, behaviour and creativity: it is a call to action, enlisting readers in their own journey of self-discovery. |

| color constancy in psychology: Discovering the Brain National Academy of Sciences, Institute of Medicine, Sandra Ackerman, 1992-01-01 The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the Decade of the Brain by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a field guide to the brainâ€an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€and how a gut feeling actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the Decade of the Brain, with a look at medical imaging techniquesâ€what various technologies can and cannot tell usâ€and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€and many scientists as wellâ€with a helpful guide to understanding the many discoveries that are sure to be announced throughout the Decade of the Brain. |
