Perceptual learning by Manfred Fahle( Book )

14 editions published in 2002 in English and Undetermined and held by 318 WorldCat member libraries worldwide

Perceptual learning is the specific and relatively permanent modification of perception and behavior following sensory experience. It encompasses parts of the learning process that are independent from conscious forms of learning and involve structural and/or functional changes in primary sensory cortices. A familiar example is the treatment for a "lazy" or crossed eye. Covering the good eye causes gradual improvement in the weaker eye's cortical representations. If the good eye is patched too long, however, it learns to see less acutely. This book presents advances made in the last decade in this rapidly growing field. The first part examines neuronal changes caused by lesions or external influences. It discusses the effects of these changes on behavior and the extent to which plasticity in sensory systems is possible. Taking a broader view, the second part looks at how more conscious or systemic stimuli cause cortical changes. Clinical trials in which subjects are taught to recognize visual and auditory stimuli demonstrate the relationship between perceptual and cognitive learning. The final sections offer general models of perceptual learning and discuss the future of the field

Vision by Man and Machine: How the Brain Processes Visual Information may be Suggested by Studies in Computer Vision (and Vice Versa) by Tomaso Poggio( Book )

8 editions published in 1984 in English and Undetermined and held by 8 WorldCat member libraries worldwide

The development of increasingly sophisticated and powerful computers in the last few decades has frequently stimulated comparisons between them and the human brain. Such comparisons will become more earnest as computers are applied more and more to tasks formerly associated with essentially human activities and capabilities. The expectation of a coming generation of intelligent computers and robots with sensory, motor and even intellectual skills comparable in quality to our own is becoming more widespread and is leading to a new and potentially productive analytical science of information processing. In no field has this new approach been so precisely formulated and so thoroughly exemplified as in the field of vision. As the dominant sensory modality of man, vision is one of the major keys to our mastery of the environment, to our understanding and control of the objects wich surroud us. If we wish to create robots capable of performing complex manipulative tasks in a changing environment, we must surely endow them with (among other things) adequate visual powers. How can we set about designing such flexible and adaptive robots? In designing them, can we make use of our rapidly growing knowledge of the human brain, and if so, how at the same time, can our experience in designing artificial vision systems help us to understand how the brain analyzes visual information?
Cooperative computation of stereo disparity by David Marr( Book )

4 editions published in 1976 in English and held by 6 WorldCat member libraries worldwide

The extraction of stereo disparity information from two images depends upon establishing a correspondence between them. This article analyzes the nature of the correspondence computation, and derives a cooperative algorithm that implements it. It is show that this algorithm successfully extracts information from random-dot stereograms, and its implications for the psychophysics and neurophysiology of the visual system are briefly discussed

From understanding computation to understanding neural circuitry by David Marr( Book )

3 editions published in 1976 in English and held by 6 WorldCat member libraries worldwide

The CNS needs to be understood at four nearly independent levels of description: (1) that at which the nature of a computation is expressed; (2) that at which the algorithms that implement a computation are characterized; (3) that at which an algorithm is committed to particular mechanisms; and (4) that at which the mechanisms are realized in hardware. In general, the nature of a computation is determined by the problem to be solved, the mechanisms that are used depend upon the available hardware, and the particular algorithms chosen depend on the problem and on the available mechanisms. Examples are given of theories at each level. (Author)

On edge detection by Vincent Torre( Book )

4 editions published in 1984 in English and held by 5 WorldCat member libraries worldwide

Edge detection is the process that attempts to characterize the intensity changes in the image in terms of the physical processes that have originated them. A critical, intermediate goal of edge detection is the detection and characterization of significant intensity changes. This paper discusses this part of the edge detection problem. To characterize the types of intensity changes derivatives of different types, and possibly different scales, are needed. Thus, we consider this part of edge detection as a problem in numerical differentiation. We show that numerical differentiation of images is an ill-posed problem in the sense of Hadamard. Differentiation needs to be regularized by a regularizing filtering operation before differentiation. This shows that this part of edge detection consists of two steps, a filtering step and a differentiation step. We discuss recent results on the behavior and the information content of zero crossings obtained with filters of different sizes. These results imply a specific order in the sequence of filtering and differentiation operations. Topological properties are preserved by level-crossings
Scaling Theorems for Zero-Crossings by A. L Yuille( Book )

4 editions published in 1983 in English and held by 4 WorldCat member libraries worldwide

The authors characterize some properties of the zero-crossings of the laplacian of signals - in particular images - filtered with linear filters, as a function of the scale of the filter. They prove that in any dimension the only filter that does not create zero-crossings as the scale increases is the gaussian. This result can be generalized to apply to level-crossings of any linear differential operator: it applies in particular to ridges and ravines in the image intensity. In case of the second derivative along the gradient it is proved that there is no filter that avoids creation of zero-crossings
A theory of human stereo vision by David Marr( Book )

2 editions published in 1977 in English and held by 4 WorldCat member libraries worldwide

An algorithm is proposed for solving the stereoscopic matching problem. The algorithm consists of five steps: (1) Each image is filtered with bar masks of four sizes that vary with eccentricity; the equivalent filters are about one octave wide. (2) Zero-crossings of the mask values are localized, and positions that correspond to terminations are found; (3) For each mask size, matching takes place between paris of zero-crossings or terminations of the same sign in the two images, for a range of disparities up to about the width of the mask's central region; (4) Wide masks can control vergence movements, thus causing small masks to come into correspondence; and (5) When a correspondence is achieved, it is written into a dynamic buffer, called the 2-1/2-D sketch. It is shown that this proposal provides a theoretical framework for most existing psychophysical and neurophysiological data about stereopsis. Several critical experimental predictions are also made, for instance about the size of Panum's area under various conditions. The results of such experiments would tell us whether, for example, cooperativity is necessary for the fusion process
An analog model of computation for the ill posed problems of early vision by Tomaso Poggio( Book )

4 editions published in 1984 in English and held by 4 WorldCat member libraries worldwide

A large gap exists at present between computational theories of vision and their possible implementation in neural hardware. The model of computation provided by the digital computer is clearly unsatisfactory for the neurobiologist, given the increasing evidence that neurons are complex devices, very different from simple digital switches. It is especially difficult to imagine how networks of neurons may solve the equations involved in vision algorithms in a way similar to digital computers. In this paper, we suggest an analog model of computation in electrical or chemical networks for a large class of vision problems, that maps more easily into biologically plausible mechanisms. Poggio and Torre have recently recognized that early vision problems such as motion analysis, edge detection, surface interpolation, shape-from shading and stereo matching can be characterized as mathematically ill-posed problems. Ill-posed problems can be solved, according to regularization theories, by variational principles of a specific type. A natural way of implementing variational problems are electrical, chemical or neuronal networks. We present specific networks for solving several low-level vision problems, such as the computation of visual motion and edge detection
