Available in PDF, EPUB and Kindle. Book excerpt: The distinguished contributors to this volume have been set the problem of describing how we know where to move our eyes. There is a great deal of current interest in the use of eye movement recordings to investigate various mental processes. The common theme is that variations in eye movements indicate variations in the processing of what is being perceived, whether in reading, driving or scene perception. However, a number of problems of interpretation are now emerging, and this edited volume sets out to address these problems. The book investigates controversies concerning the variations in eye movements associated with reading ability, concerning the extent to which text is used by the guidance mechanism while reading, concerning the relationship between eye movements and the control of other body movements, the relationship between what is inspected and what is perceived, and concerning the role of visual control attention in the acquisition of complex perceptual-motor skills, in addition to the nature of the guidance mechanism itself. The origins of the volume are in discussions held at a meeting of the European Society for Cognitive Psychology (ESCOP) that was held in Wurzburg in September 1996. The discussions concerned the landing effect in reading, an effect, that if substantiated, would provide evidence of the use of parafoveal information in eye guidance, and these discussions were explored in more detail at a small meeting in Chamonix, in February 1997. Many of the contributors to this volume were present at the meeting, but the arguments were not resolved in Chamonix either. Other leaders in the field were invited to contribute to the discussion, and this volume is the product. The argument remains unresolved, but the problem is certainly clearer.

Book excerpt: The goal of the research was to understand the role of contextual constraint in the visual analysis of complex, natural scenes. This issue bears directly on the basic architecture of the human visual system and has implications for the design of artificial vision systems devoted to object and scene analysis. Two hypotheses were considered: (1) Scene constraint influences the perceptual identification of individual objects; and (2) Scene constraint influences only post-identification object analysis. The main results of the research support the first hypothesis: Scene constraint does not directly influence perceptual analysis of component objects in human vision. Other results from the research supports the conclusion that semantic information is not used to drive initial eye movements in a scene, but does influence initial fixation time in a region and region refixation probability. Based on these results. a model of scene analysis was developed in which object identification is functionally isolated from scene meaning and gaze control is initially independent of scene semantics but becomes sensitive to meaning as scene perception unfolds over time. Continuing work is currently aimed at testing this model in human vision and gaze control, and implementing an artificial gaze control system on a working robot platform using a Markov Decision Process framework.

Available in PDF, EPUB and Kindle. Book excerpt: Visual cognitive processes have traditionally been examined with simplified stimuli, but generalization of these processes to the real-world is not always straightforward. Using images, computer-generated images, and virtual environments, researchers have examined processing of visual information in the real-world. Although referred to as scene perception, this research field encompasses many aspects of scene processing. Beyond the perception of visual features, scene processing is fundamentally influenced and constrained by semantic information as well as spatial layout and spatial associations with objects. In this review, we will present recent advances in how scene processing occurs within a few seconds of exposure, how scene information is retained in the long-term, and how different tasks affect attention in scene processing. By considering the characteristics of real-world scenes, as well as different time windows of processing, we can develop a fuller appreciation for the research that falls under the wider umbrella of scene processing.

Available in PDF, EPUB and Kindle. Book excerpt: The current volume, a special issue of Visual Cognition, brings together an eclectic group of investigators, all of whom study critical issues in the perception of true real-world scenes. Topics include the rapid acquisition of scene gist; scene recognition; spatial layout and spatial scale; distance perception in scenes; updating of scene views over time; visual search for meaningful objects in scenes; scene context effects on object perception; scene representation in memory; the allocation of attention including eye fixations during scene viewing; and the neural implementation of these representations and processes in the brain. Because the study of real-world scene perception benefits from an interdisciplinary approach, contributors to the volume use a variety of research methods including psychophysical and behavioral techniques, eyetracking, functional neuroimaging (including fMRI and ERP), and mathematical and computational modeling. While much has been learned from studying simplified visual stimuli, many of the articles in this volume make the important point that understanding the functional and neural architectures of the visual system requires studying how that system operates when faced with the types of real-world stimuli that evolution crafted it to handle.

Download or read book Representations and Techniques for 3D Object Recognition and Scene Interpretation written by Derek Hoiem and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the grand challenges of artificial intelligence is to enable computers to interpret 3D scenes and objects from imagery. This book organizes and introduces major concepts in 3D scene and object representation and inference from still images, with a focus on recent efforts to fuse models of geometry and perspective with statistical machine learning. The book is organized into three sections: (1) Interpretation of Physical Space; (2) Recognition of 3D Objects; and (3) Integrated 3D Scene Interpretation. The first discusses representations of spatial layout and techniques to interpret physical scenes from images. The second section introduces representations for 3D object categories that account for the intrinsically 3D nature of objects and provide robustness to change in viewpoints. The third section discusses strategies to unite inference of scene geometry and object pose and identity into a coherent scene interpretation. Each section broadly surveys important ideas from cognitive science and artificial intelligence research, organizes and discusses key concepts and techniques from recent work in computer vision, and describes a few sample approaches in detail. Newcomers to computer vision will benefit from introductions to basic concepts, such as single-view geometry and image classification, while experts and novices alike may find inspiration from the book's organization and discussion of the most recent ideas in 3D scene understanding and 3D object recognition. Specific topics include: mathematics of perspective geometry; visual elements of the physical scene, structural 3D scene representations; techniques and features for image and region categorization; historical perspective, computational models, and datasets and machine learning techniques for 3D object recognition; inferences of geometrical attributes of objects, such as size and pose; and probabilistic and feature-passing approaches for contextual reasoning about 3D objects and scenes. Table of Contents: Background on 3D Scene Models / Single-view Geometry / Modeling the Physical Scene / Categorizing Images and Regions / Examples of 3D Scene Interpretation / Background on 3D Recognition / Modeling 3D Objects / Recognizing and Understanding 3D Objects / Examples of 2D 1/2 Layout Models / Reasoning about Objects and Scenes / Cascades of Classifiers / Conclusion and Future Directions

Available in PDF, EPUB and Kindle. Book excerpt: From a barrage of photons, we readily and effortlessly recognize the faces of our friends, and the familiar objects and scenes around us. However, these tasks cannot be simple for our visual systems--faces are all extremely similar as visual patterns, and objects look quite different when viewed from different viewpoints. How do our visual systems solve these problems? The contributors to this volume seek to answer this question by exploring how analytic and holistic processes contribute to our perception of faces, objects, and scenes. The role of parts and wholes in perception has been studied for a century, beginning with the debate between Structuralists, who championed the role of elements, and Gestalt psychologists, who argued that the whole was different from the sum of its parts. This is the first volume to focus on the current state of the debate on parts versus wholes as it exists in the field of visual perception by bringing together the views of the leading researchers. Too frequently, researchers work in only one domain, so they are unaware of the ways in which holistic and analytic processing are defined in different areas. The contributors to this volume ask what analytic and holistic processes are like; whether they contribute differently to the perception of faces, objects, and scenes; whether different cognitive and neural mechanisms code holistic and analytic information; whether a single, universal system can be sufficient for visual-information processing, and whether our subjective experience of holistic perception might be nothing more than a compelling illusion. The result is a snapshot of the current thinking on how the processing of wholes and parts contributes to our remarkable ability to recognize faces, objects, and scenes, and an illustration of the diverse conceptions of analytic and holistic processing that currently coexist, and the variety of approaches that have been brought to bear on the issues.

Book excerpt: The articles in this Research Topic provide a state-of-the-art overview of the current progress in integrating computational and empirical research on visual object recognition. Developments in this exciting multidisciplinary field have recently gained momentum: High performance computing enabled breakthroughs in computer vision and computational neuroscience. In parallel, innovative machine learning applications have recently become available for datamining the large-scale, high resolution brain data acquired with (ultra-high field) fMRI and dense multi-unit recordings. Finally, new techniques to integrate such rich simulated and empirical datasets for direct model testing could aid the development of a comprehensive brain model. We hope that this Research Topic contributes to these encouraging advances and inspires future research avenues in computational and empirical neuroscience.

Book excerpt: Originally published in 1982, this book introduces the student to the central problem of all perceptual theories: just how does the perceiver identify particular objects? In focusing on the problem, Dr Wilding provides a coherent, well organized framework for its study, bypassing the conventional split between perception and reaction time evidence which was common to most textbooks at the time. The author draws on evidence from a wider number of research traditions and argues that each has a contribution to make to any account of perception. Throughout he emphasizes the methodological basis of the research discussed, in order to provide students with a solid foundation for their own practical work.

Book excerpt: This collection of research on object perception focuses on holistic and featural properties of objects, the mechanisms that produce such properties, how people choose one type of property over another, and how such choices are improved during the course of child development. The contributions consider alternative perceptual characterizations, the way in which such properties are represented in the mind, how particular properties are more useful in some kinds of tasks that humans perform, and how the developing child learns to cope with different properties in choosing among alternatives to optimize task performance. These papers were written by specialists for specialists in experimental, cognitive, and developmental psychology.

This book was released on 2012-12-06 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface properties play a very important role in many perception tasks. Object recognition, navigation, and inspection use surface properties ex tensively. Characterizing surfaces at different scales in given data is often the first and possibly the most important step. Most early research in ma chine perception relied on only very coarse characterization of surfaces. In the last few years, surface characterization has been receiving due attention. Dr. T. J. Fan is one of the very few researchers who designed and im plemented a complete system for object recognition. He studied issues re lated to characterization of surfaces in the context of object recognition, and then uses the features thus developed for recognizing objects. He uses a multi-view representation of 3-D objects for recognition, and he devel ops techniques for the segmentation of range images to obtain features for recognition. His matching approach also allows him to recognize objects from their partial views in the presence of other occluding objects. The efficacy of his approach is demonstrated in many examples.

Download or read book What It Is Like To Perceive written by J. Christopher Maloney and published by Oxford University Press. This book was released on 2018-06-15 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Naturalistic cognitive science, when realistically rendered, rightly maintains that to think is to deploy contentful mental representations. Accordingly, conscious perception, memory, and anticipation are forms of cognition that, despite their introspectively manifest differences, may coincide in content. Sometimes we remember what we saw; other times we predict what we will see. Why, then, does what it is like consciously to perceive, differ so dramatically from what it is like merely to recall or anticipate the same? Why, if thought is just representation, does the phenomenal character of seeing a sunset differ so stunningly from the tepid character of recollecting or predicting the sun's descent? J. Christopher Maloney argues that, unlike other cognitive modes, perception is in fact immediate, direct acquaintance with the object of thought. Although all mental representations carry content, the vehicles of perceptual representation are uniquely composed of the very objects represented. To perceive the setting sun is to use the sun and its properties to cast a peculiar cognitive vehicle of demonstrative representation. This vehicle's embedded referential term is identical with, and demonstrates, the sun itself. And the vehicle's self-attributive demonstrative predicate is itself forged from a property of that same remote star. So, in this sense, the perceiving mind is an extended mind. Perception is unbrokered cognition of what is real, exactly as it really is. Maloney's theory of perception will be of great interest in the philosophy of mind and cognitive science.
