An accessible yet rigorous and generously illustrated exploration of the computational approach to the study of biological vision. Seeing has puzzled scientists and philosophers for centuries and it continues to do so. This new edition of a classic text offers an accessible but rigorous introduction to the computational approach to understanding biological visual systems. The authors of Seeing, taking as their premise David Marr's statement that “to understand vision by studying only neurons is like trying to understand bird flight by studying only feathers,” make use of Marr's three different levels of analysis in the study of vision: the computational level, the algorithmic level, and the hardware implementation level. Each chapter applies this approach to a different topic in vision by examining the problems the visual system encounters in interpreting retinal images and the constraints available to solve these problems; the algorithms that can realize the solution; and the implementation of these algorithms in neurons. Seeing has been thoroughly updated for this edition and expanded to more than three times its original length. It is designed to lead the reader through the problems of vision, from the common (but mistaken) idea that seeing consists just of making pictures in the brain to the minutiae of how neurons collectively encode the visual features that underpin seeing. Although it assumes no prior knowledge of the field, some chapters present advanced material. This makes it the only textbook suitable for both undergraduate and graduate students that takes a consistently computational perspective, offering a firm conceptual basis for tackling the vast literature on vision. It covers a wide range of topics, including aftereffects, the retina, receptive fields, object recognition, brain maps, Bayesian perception, motion, color, and stereopsis. MatLab code is available on the book's website, which includes a simple demonstration of image convolution.

Have you ever wondered how a blind person pours a cup of coffee? Or how they and their guide dog know when it's safe to cross a busy road? When Lois Strachan lost her sight at the age of 21 years she had to learn the answers to these and countless other questions of how to live as a blind person in a sighted world. In this delightfully quirky and entertaining book Lois shares some of the secrets she discovered about how to live an "ordinary" life in an extraordinary way despite her blindness. "An entertaining, informative and educational read that gives you an insight into the life of an inspirational woman who lives life to the fullest. Well worth reading." Gail Glover - Executive Director, South African Guide-Dogs Association for the Blind "A must-read for anyone, with or without a disability." Hanif Kruger -Resource Centre Manager, South African National Council for the Blind "Lois's stories provide insights on how to positively deal with the challenges in life to emerge victorious." Bob "Idea Man Hooey - author of "Why didn't I THINK of that?" "In her fascinating account of the life of a blind person, Lois Strachan lifts the lid on aspects of life that most of us take for granted. We should all learn a lot from Lois's different way of seeing." George Mahood - Author of Free Country & Every Day is a Holiday

The First Steps in Seeing is about the eyes, and how they capture an image and convert it to the neural messages that ultimately result in visual experience. A full appreciation of how the eyes work is rooted in diverse areas of science-optics; biochemistry and photochemistry; molecular biology, cell biology, neurobiology, and evolutionary biology; psychology and psychophysics. The findings related to vision from any one of these fields are not difficult to understand in themselves, but, in order to be clear and precise, each discipline has developed its own set of words and conceptual relations-in effect, its own language-and for those wanting a broad introduction to vision these separate languages can present more of an impediment to understanding than an aid. However, what lies beneath these words usually has a beautiful simplicity, and it is the aim of The First Steps in Seeing to describe how we see in a manner that is understandable to all. In this book, the use of technical terms is restricted, and several hundred full-color illustrations ensure that the terms that are used are associated with a picture, icon, or graph that visually expresses their meaning. Experimental findings have been recast in terms of the natural world whenever possible, and broad themes bring together lines of thought that are often treated separately. Fourteen main chapters form a "thread" that tells the main scientific story and can be read without specialized knowedge or reliance on other sources. This thread is linked to fourteen discussions which explore certain crucial topics in greater depth. Notes link the material presented in the thread and in the special topics discussions to important review articles and seminal research papers. The First Steps in Seeing is an innovative, authoritative work that belongs in the library of anyone with an interest in visual perception.

There is a lot more to photography than simply picking up a camera, pointing it toward something, and tripping the shutter. Achieving a great photograph requires thought and preparation, an understanding of the photographic process, and a firm grasp of how light and composition affect a photo. There must be personal involvement and personal expression. There must be experimentation, with the recognition that only a small percentage of experiments end successfully. In this book, best-selling author and world-renowned photographer and teacher Bruce Barnbaum explores these seldom-discussed issues by drawing upon his personal experiences and observations from more than 40 years of photographing and teaching. In addition to photographs, Bruce also uses painting, music, and writing, as well as the sciences and even business, to provide pertinent examples of creative thinking. These examples serve as stepping-stones that will lead you to your own heightened ability to see and be creative. Creativity is a topic that is almost wholly ignored in formal education because most instructors think that it cannot be taught or learned. To the contrary, Bruce has proven that photographic seeing and creativity can be taught, learned, and improved. This book expands on the ideas that are central to Bruce's method of teaching photography, which he has used in workshops for the past 41 years. Included in the book are in-depth discussions on the following topics: Defining your own unique rhythm and approach as a photographer How to translate the scene in front of you to the final photograph The differences and similarities between how an amateur and a professional approach photography The differences between realism and abstraction, and the possibilities and limitations of each Learning to expand your own seeing and creativity through classes, workshops, and associating with other photographers Why the rules of composition should be ignored How to follow your passion When to listen to the critics and when to ignore them The book is richly illustrated with over 90 photographs taken by Bruce as well as other photographers.Seeing and creativity are difficult to teach, but not impossible. This very different, perhaps groundbreaking book is sure to inspire photographers of all skill levels-from beginners to seasoned professionals-to think deeply about the issues involved in creating successful photographs.

“A brilliantly inventive account of the evolution of consciousness, the best yet” (Paul Broks, Prospect). “Consciousness matters. Arguably it matters more than anything. The purpose of this book is to build towards an explanation of just what the matter is.” Nicholas Humphrey begins this compelling exploration of the biggest of big questions with a challenge to the reader, and himself. What’s involved in “seeing red”? What is it like for us to see someone else seeing something red? Seeing a red screen tells us a fact about something in the world. But it also creates a new fact—a sensation in each of our minds, the feeling of redness. And that’s the mystery. Conventional science so far hasn’t told us what conscious sensations are made of, or how we get access to them, or why we have them at all. From an evolutionary perspective, what’s the point of consciousness? Humphrey offers a daring and novel solution, arguing that sensations are not things that happen to us, they are things we do—originating in our primordial ancestors’ expressions of liking or disgust. Tracing the evolutionary trajectory through to human beings, he shows how this has led to sensations playing the key role in the human sense of Self. The Self, as we now know it from within, seems to have fascinating other-worldly properties. It leads us to believe in mind-body duality and the existence of a soul. And such beliefs—even if mistaken—can be highly adaptive, because they increase the value we place on our own and others’ lives. “Consciousness matters,” Humphrey concludes with striking paradox, “because it is its function to matter. It has been designed to create in human beings a Self whose life is worth pursuing.” Praise for Seeing Red “A wonderful amalgam of science, philosophy, and art. [Seeing Red] is based on deep knowledge of visual processing by the brain and poetic understanding of human experience. This is a remarkable achievement.” —Richard Gregory, Emeritus Professor of Neuropsychology, University of Bristol, and editor of The Oxford Companion to the Mind “A brief, brilliant, and wonderfully lucid contribution to consciousness studies. By combining empirical scientific method, evolutionary theory, and a sensitive appreciation of the arts, Nicholas Humphrey argues plausibly that the “hard problem” of consciousness—the difficulty of explaining the connection between the material brain and the phenomenon of individual selfhood—may itself be the answer to a bigger question: what makes us human?”—David Lodge, author of Consciousness and the Novel: Connected Essays “Illustrating his argument with the musings of poets and painters, Humphrey stylishly inspires curiosity about consciousness.” —Gilbert Taylor, Booklist
