Moments as projections of an image’s intensity onto a proper polynomial basis can be applied to many different aspects of image processing. These include invariant pattern recognition, image normalization, image registration, focus/ defocus measurement, and watermarking. This book presents a survey of both recent and traditional image analysis and pattern recognition methods, based on image moments, and offers new concepts of invariants to linear filtering and implicit invariants. In addition to the theory, attention is paid to efficient algorithms for moment computation in a discrete domain, and to computational aspects of orthogonal moments. The authors also illustrate the theory through practical examples, demonstrating moment invariants in real applications across computer vision, remote sensing and medical imaging. Key features: Presents a systematic review of the basic definitions and properties of moments covering geometric moments and complex moments. Considers invariants to traditional transforms – translation, rotation, scaling, and affine transform - from a new point of view, which offers new possibilities of designing optimal sets of invariants. Reviews and extends a recent field of invariants with respect to convolution/blurring. Introduces implicit moment invariants as a tool for recognizing elastically deformed objects. Compares various classes of orthogonal moments (Legendre, Zernike, Fourier-Mellin, Chebyshev, among others) and demonstrates their application to image reconstruction from moments. Offers comprehensive advice on the construction of various invariants illustrated with practical examples. Includes an accompanying website providing efficient numerical algorithms for moment computation and for constructing invariants of various kinds, with about 250 slides suitable for a graduate university course. Moments and Moment Invariants in Pattern Recognition is ideal for researchers and engineers involved in pattern recognition in medical imaging, remote sensing, robotics and computer vision. Post graduate students in image processing and pattern recognition will also find the book of interest.
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.
A comprehensive and integrated introduction to the phenomena and theories of perceptual learning, focusing on the visual domain. Practice or training in perceptual tasks improves the quality of perceptual performance, often by a substantial amount. This improvement is called perceptual learning (in contrast to learning in the cognitive or motor domains), and it has become an active area of research of both theoretical and practical significance. This book offers a comprehensive introduction to the phenomena and theories of perceptual learning, focusing on the visual domain. Perceptual Learning explores the tradeoff between the competing goals of system stability and system adaptability, signal and noise, retuning and reweighting, and top-down versus bottom-down processes. It examines and evaluates existing research and potential future directions, including evidence from behavior, physiology, and brain imaging, and existing perceptual learning applications, with a focus on important theories and computational models. It also compares visual learning to learning in other perceptual domains, and considers the application of visual training methods in the development of perceptual expertise and education as well as in remediation for limiting visual conditions. It provides an integrated treatment of the subject for students and researchers and for practitioners who want to incorporate perceptual learning into their practice.Practice or training in perceptual tasks improves the quality of perceptual performance, often by a substantial amount. This improvement is called perceptual learning, in contrast with learning in the cognitive or motor domains. Perceptual learning has been a very active area of research of both theoretical and practical interest. Research on perceptual learning is of theoretical significance in illuminating plasticity in adult perceptual systems, and in understanding the limitations of human information processing and how to improve them. It is of practical significance as a potential method for the development of perceptual expertise in the normal population, for its potential in advancing development and supporting healthy aging, and for noninvasive amelioration of deficits in challenged populations by training. Perceptual learning has become an increasingly important topic in biomedical research. Practitioners in this area include science disciplines such as psychology, neuroscience, computer sciences, and optometry, and developers in applied areas of learning game design, cognitive development and aging, and military and biomedical applications. Commercial development of training products, protocols, and games is a multi-billion dollar industry. Perceptual learning provides the basis for many of the developments in these areas. This book is written for anyone who wants to understand the phenomena and theories of perceptual learning or to apply the technology of perceptual learning to the development of training methods and products. Our aim is to provide an introduction to those researchers and students just entering this exciting field, to provide a comprehensive and integrated treatment of the phenomena and the theories of perceptual learning for active perceptual learning researchers, and to describe and develop the basic techniques and principles for readers who want to successfully incorporate perceptual learning into applied developments. The book considers the special challenges of perceptual learning that balance the competing goals of system stability and system adaptability. It provides a systematic treatment of the major phenomena and models in perceptual learning, the determinants of successful learning and of specificity and transfer. The book provides a cohesive consideration of the broad range of perceptual learning through the theoretical framework of incremental learning of reweighting evidence that supports successful task performance. It provides a detailed analysis of the mechanisms by which perceptual learning improves perceptual limitations, the relationship of perceptual learning and the critical period of development, and the semi-supervised modes of learning that dominate perceptual learning. It considers limitations and constraints on learning multiple tasks and stimuli simultaneously, the implications of training at high or low levels of performance accuracy, and the importance of feedback to perceptual learning. The basis of perceptual learning in physiology is discussed along with the relationship of visual perceptual learning to learning in other sensory domains. The book considers the applications of perceptual learning in the development of expertise, in education and gaming, in training during development and aging, and applications to remediation of mental health and vision disorders. Finally, it applies the phenomena and models of perceptual learning to considerations of optimizing training.
This book presents established and state-of-the-art methods in Language Technology (including text mining, corpus linguistics, computational linguistics, and natural language processing), and demonstrates how they can be applied by humanities scholars working with textual data. The landscape of humanities research has recently changed thanks to the proliferation of big data and large textual collections such as Google Books, Early English Books Online, and Project Gutenberg. These resources have yet to be fully explored by new generations of scholars, and the authors argue that Language Technology has a key role to play in the exploration of large-scale textual data. The authors use a series of illustrative examples from various humanistic disciplines (mainly but not exclusively from History, Classics, and Literary Studies) to demonstrate basic and more complex use-case scenarios. This book will be useful to graduate students and researchers in humanistic disciplines working with textual data, including History, Modern Languages, Literary studies, Classics, and Linguistics. This is also a very useful book for anyone teaching or learning Digital Humanities and interested in the basic concepts from computational linguistics, corpus linguistics, and natural language processing.

Heroes lead, inspire, and perform memorable acts that shape the lives of others. In the pages of this book, readers will learn the stories behind Kearny's heroes--the people whose contributions made Kearny into the thriving, diverse community it is today. Ed Karolasz gave his life for his country during the war in Iraq. Councilman Norman Doyle helped a young girl get the medical attention she needed. College student Gabriela Salvador restores historic costumes for the town museum. Real estate developers Louis Lindblom and Edward Strong built the town's financial institutions and the Arlington section. Educators Peg Bixler and Barbara Toczko devoted themselves to their students. From the town known as Soccertown, USA, came John Harkes, Tony Meola, and Tab Ramos, who played on the United States team in the FIFA World Cup. But there was also Louis Eilshemius, the somewhat mad and reclusive artist, and Albert Gonzalez, a government informant and computer criminal. This "City of Opportunity" has produced more than its share of personalities that have created admirable and notorious international, national, and local legends.

Representing Imperial Rivalry in the Early Modern Mediterranean explores representations of national, racial, and religious identities within a region dominated by the clash of empires. Bringing together studies of English, Spanish, Italian, and Ottoman literature and cultural artifacts, the volume moves from the broadest issues of representation in the Mediterranean to a case study – early modern England – where the “Mediterranean turn” has radically changed the field. The essays in this wide-ranging literary and cultural study examine the rhetoric which surrounds imperial competition in this era, ranging from poems commemorating the battle of Lepanto to elaborately adorned maps of contested frontiers. They will be of interest to scholars in fields such as history, comparative literary studies, and religious studies.
Barbara Theodosiou and her family reveal the pain, loss, and connection that emerge from addiction, trauma, codependency, and recovery in this unique view into the heart of a national crisis. The ringing phone startles Barbara during another sleepless night. She knows it must be Daniel, her big-hearted, intelligent son who has spent years cycling through hospitals, jails, and treatment centers. Although Daniel’s childhood struggles started much earlier, he was sixteen when Barbara discovered he was horribly addicted to DXM, the drug found in many over-the-counter cough medicines. After picking up the pieces from one more of her son’s relapses, Barbara seeks support in the online refuge she created when she had nowhere else to turn: The Addict’s Mom. There, she can “Share Without Shame” with others who understand. These other mothers know that it can become normal to hope your son will be locked up so he isn’t sleeping on the street. These other moms understand how it feels to realize you have not just one addicted child but two--Barbara discovered her oldest son Peter’s addiction just six months after Daniel’s. And when that happens, sometimes all a mother can do is try to save herself. But this isn’t just a mother’s story. Without Shame encompasses Daniel’s own poetry and prose, Peter’s story of healing against all odds, their sister Nicole’s story of balancing compassion and independence, and other often unheard voices. This multifaceted story reveals what it truly means to describe addiction as a family disease.

This book examines the birth of the scientific understanding of motion. It investigates which logical tools and methodological principles had to be in place to give a consistent account of motion, and which mathematical notions were introduced to gain control over conceptual problems of motion. It shows how the idea of motion raised two fundamental problems in the 5th and 4th century BCE: bringing together being and non-being, and bringing together time and space. The first problem leads to the exclusion of motion from the realm of rational investigation in Parmenides, the second to Zeno's paradoxes of motion. Methodological and logical developments reacting to these puzzles are shown to be present implicitly in the atomists, and explicitly in Plato who also employs mathematical structures to make motion intelligible. With Aristotle we finally see the first outline of the fundamental framework with which we conceptualise motion today.
Attached at the Heart offers readers practical parenting advice for the modern age. In its most basic form, "attachment parenting" is instinctive. A crying baby is comforted and kept close to parents for protection. If hungry, he or she is breastfed. And while it is understood that there is no such thing as perfect parenting, research suggests that there is a strong correlation between a heightened sense of respect, empathy, and affection in those children raised the "attachment parenting" way. In this controversial book, readers will gain much needed insight into childrearing while learning to trust the intuitive knowledge of their child, ultimately building a strong foundation that will strengthen the parent-child bond. Contrary to popular belief, "attachment parenting" has been practiced in one form or another since recorded history. Over the years, it had been slowly replaced by a more detached parenting style—a style that is now believed by experts to be a lead contributing factor to suicide, depression, and violence. The concept of "attachment parenting"—a term originally coined by parenting experts William and Martha Sears—has increasingly been validated by research in many fields of study, such as child development, psychology, and neuroscience. Also known as "conscious parenting," "natural parenting," "compassionate parenting," or "empathic parenting," its goal is to stimulate optimal child development. While many attachment-parenting recommendations likely counter popular societal beliefs, authors Barbara Nicholson and Lysa Parker are quick to point out that the benefits outweigh the backlash of criticism that advocates of detached parenting may impose.
