Available in PDF, EPUB and Kindle. Book excerpt: Aims and Scope This book is both an introductory textbook and a research monograph on modeling the statistical structure of natural images. In very simple terms, “natural images” are photographs of the typical environment where we live. In this book, their statistical structure is described using a number of statistical models whose parameters are estimated from image samples. Our main motivation for exploring natural image statistics is computational m- eling of biological visual systems. A theoretical framework which is gaining more and more support considers the properties of the visual system to be re?ections of the statistical structure of natural images because of evolutionary adaptation processes. Another motivation for natural image statistics research is in computer science and engineering, where it helps in development of better image processing and computer vision methods. While research on natural image statistics has been growing rapidly since the mid-1990s, no attempt has been made to cover the ?eld in a single book, providing a uni?ed view of the different models and approaches. This book attempts to do just that. Furthermore, our aim is to provide an accessible introduction to the ?eld for students in related disciplines.

Download or read book Image Processing in the Human Visual System written by Brent Baxter and published by . This book was released on 1975 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work extends the multiplicative visual model to include image texture as suggested by previous experiments linking a low resolution Fourier analysis with neurons in certain parts of the visual cortex. The new model takes image texture into account in the sense that weak texture is accentuated and strong, high contrast texture is attenuated. This model is then used as the basis for an improved image enhancement scheme and an unusually successful method for restoring blurred images. In addition, it is suggested how the model may provide new insights into the problem of finding a quantitatively correct image fidelity criterion. The structure of this model is described in relation to visual neurophysiology and examples are presented of images processed by the new techniques. The present research also shows how Land's 'retinex' can be implemented in a new way which allows the required computations to be carried out on a rectangular grid.

Download or read book Vision written by David Marr and published by MIT Press. This book was released on 2010-07-09 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available again, an influential book that offers a framework for understanding visual perception and considers fundamental questions about the brain and its functions. David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood. Researchers from a range of brain and cognitive sciences have long valued Marr's creativity, intellectual power, and ability to integrate insights and data from neuroscience, psychology, and computation. This MIT Press edition makes Marr's influential work available to a new generation of students and scientists. In Marr's framework, the process of vision constructs a set of representations, starting from a description of the input image and culminating with a description of three-dimensional objects in the surrounding environment. A central theme, and one that has had far-reaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis—in Marr's framework, the computational level, the algorithmic level, and the hardware implementation level. Now, thirty years later, the main problems that occupied Marr remain fundamental open problems in the study of perception. Vision provides inspiration for the continuing efforts to integrate knowledge from cognition and computation to understand vision and the brain.
Download or read book Representation of Natural Image Sequences in the Primate Visual System written by Yoon Ho Bai and published by . This book was released on 2020 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental goal of sensory processing is predicting the future state of the environment. Visual prediction is difficult because the stream of images on the retina evolves according to irregular, curved trajectories. We posit that the visual system seeks to transform natural inputs such that neural representations follow straighter and more predictable trajectories. Previous work has provided psychophysical evidence for this hypothesis by showing that the human visual system selectively straightens the temporal trajectories of natural movies, thus facilitating their extrapolation. In this thesis, I investigate the neural basis of perceptual straightening. We hypothesize that perceptual straightening is achieved through a series of cascaded transformations and found supporting evidence from psychophysical and neurophysiological measurements. We estimated the curvature of internal trajectories from human perceptual judgements across distinct sub-regions of the visual field. Perceptual results suggest that computations that underlie object recognition overlap with those that straighten natural movies, thereby revealing deficits in both processes--crowding and absence of straightening in the periphery. We posit that straightening occurs at multiple stages in the ventral stream as it is linked to recognizing objects. Next, we investigated if straightening occurs as early as the primary visual cortex (V1). We developed a novel computational tool to infer trajectories from neural populations and found robust straightening in V1 recordings from anesthetized macaques. Next, we explored the computational basis of V1 results with an image-computable model. We built a model to describe well-known computations of V1 cells and tested the model with the same movie stimuli. Model-predictions reveal that these computations only partially engage the mechanisms for straightening, revealing the involvement of more complex visual mechanisms. To further test our hypothesis, we asked if additional straightening occurs across the V1-V2 cascade. We recorded populations in areas V1 and V2 from awake fixating monkeys. Consistent with our hypothesis, we find incremental straightening between V1 and V2 elicited by the same natural movies. Together, we find collective evidence of neural straightening as an emergent property that contributes to perceptual straightening in a progressive manner starting from the early stages of vision

Download or read book Biologically Inspired Computer Vision written by Gabriel Cristobal and published by John Wiley & Sons. This book was released on 2015-08-20 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the state-of-the-art imaging technologies became more and more advanced, yielding scientific data at unprecedented detail and volume, the need to process and interpret all the data has made image processing and computer vision increasingly important. Sources of data that have to be routinely dealt with today's applications include video transmission, wireless communication, automatic fingerprint processing, massive databanks, non-weary and accurate automatic airport screening, robust night vision, just to name a few. Multidisciplinary inputs from other disciplines such as physics, computational neuroscience, cognitive science, mathematics, and biology will have a fundamental impact in the progress of imaging and vision sciences. One of the advantages of the study of biological organisms is to devise very different type of computational paradigms by implementing a neural network with a high degree of local connectivity. This is a comprehensive and rigorous reference in the area of biologically motivated vision sensors. The study of biologically visual systems can be considered as a two way avenue. On the one hand, biological organisms can provide a source of inspiration for new computational efficient and robust vision models and on the other hand machine vision approaches can provide new insights for understanding biological visual systems. Along the different chapters, this book covers a wide range of topics from fundamental to more specialized topics, including visual analysis based on a computational level, hardware implementation, and the design of new more advanced vision sensors. The last two sections of the book provide an overview of a few representative applications and current state of the art of the research in this area. This makes it a valuable book for graduate, Master, PhD students and also researchers in the field.
