Available in PDF, EPUB and Kindle. Book excerpt: The physical processes which initiate and maintain motion have been a major concern of serious investigation throughout the evolution of scientific thought. As early as the fifth century B. C. questions regarding motion were presented as touchstones for the most fundamental concepts about existence. Such wide ranging philosophical issues are beyond the scope of this book, however, consider the paradox of the flying arrow attri buted to Zeno of Elea: An arrow is shot from point A to point B requiring a sequence of time instants to traverse the distance. Now, for any time instant, T, of the sequence the arrow is at a position, Pi' and at Ti+! the i arrow is at Pi+i> with Pi ::I-P+• Clearly, each Ti must be a singular time i 1 unit at which the arrow is at rest at Pi because if the arrow were moving during Ti there would be a further sequence, Til' of time instants required for the arrow to traverse the smaller distance. Now, regardless of the level to which this recursive argument is applied, one is left with the flight of the arrow comprising a sequence of positions at which the arrow is at rest. The original intent of presenting this paradox has been interpreted to be as an argument against the possibility of individuated objects moving in space.

Download or read book Understanding Motion Capture for Computer Animation written by Alberto Menache and published by Elsevier. This book was released on 2011-01-24 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding Motion Capture for Computer Animation discusses the latest technology developments in digital design, film, games, medicine, sports, and security engineering. Motion capture records a live-motion event and translates it into a digital context. It is the technology that converts a live performance into a digital performance. In contrast, performance animation is the actual performance that brings life to the character, even without using technology. If motion capture is the collection of data that represents motion, performance animation is the character that a performer represents. The book offers extensive information about motion capture. It includes state-of-the-art technology, methodology, and developments in the current motion-capture industry. In particular, the different ways to capture motions are discussed, including using cameras or electromagnetic fields in tracking a group of sensors. This book will be useful for students taking a course about digital filming, as well as for anyone who is interested in this topic. - Completely revised to include almost 40% new content with emphasis on RF and Facial Motion Capture Systems - Describes all the mathematical principles associated with motion capture and 3D character mechanics - Helps you budget by explaining the costs associated with individualized motion capture projects
Download or read book Qualitative Motion Understanding written by Wilhelm Burger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile robots operating in real-world, outdoor scenarios depend on dynamic scene understanding for detecting and avoiding obstacles, recognizing landmarks, acquiring models, and for detecting and tracking moving objects. Motion understanding has been an active research effort for more than a decade, searching for solutions to some of these problems; however, it still remains one of the more difficult and challenging areas of computer vision research. Qualitative Motion Understanding describes a qualitative approach to dynamic scene and motion analysis, called DRIVE (Dynamic Reasoning from Integrated Visual Evidence). The DRIVE system addresses the problems of (a) estimating the robot's egomotion, (b) reconstructing the observed 3-D scene structure; and (c) evaluating the motion of individual objects from a sequence of monocular images. The approach is based on the FOE (focus of expansion) concept, but it takes a somewhat unconventional route. The DRIVE system uses a qualitative scene model and a fuzzy focus of expansion to estimate robot motion from visual cues, to detect and track moving objects, and to construct and maintain a global dynamic reference model.
Download or read book Worlds in Motion Understanding International Migration at the End of the Millennium written by Douglas S. Massey and published by Clarendon Press. This book was released on 1999-01-28 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the end of the 20th century nearly all developed nations have become countries of immigration, absorbing growing numbers of immigrants not only from developed regions, byt increasingly from developing nations of the Third World. Although international migration has come to play a central role in the social, economic, and demographic dynamics of both immigrant-sending and immigrant-receiving countries, social scientist have been slow to construct a comprehensive theory to explain it. Efforts at theoretical explanation have been fragmented by disciplinary, geographic, and methodological boudaries. Worlds in Motion seeks to overcome these schisms to create a comprehensive theory of international migration for the next century. After explicating the various propositions and hypotheses of current theories, and identifying area of complementarity and conflict, the authors review empirical research emanting from each of the world's principal international migration systems: North America, Western Europe, the Gulf, Asia and the Pacific, and the Southern Cone of South America. Using data from the 1980s, levels and patterns of migration within each system are described to define their structure and organization. Specific studies are then comprehensively surveyed to evaluate the fundamental propositions of neoclassical economics, the new economics of labour migration, segmented labour market theory, world systems theory, social capital theory, and the theory of cumulative causation. The various theories are also tested by applying them to the relationship between international migration and economic development. Although certain theories seem to function more effectively in certain systems, all contain elements of truth supported by empirical research. The task of the theorist is thus to identify which theories are most effective in accounting for international migration in the world today, and what regional and national circumstances lead to a predominance of one theoretical mechanism over another. The book concludes by offering an empirically-grounded theoretical synthesis to serve as a guide for researchers and policy-makers in the 21st century.

Download or read book Motion History Images for Action Recognition and Understanding written by Md. Atiqur Rahman Ahad and published by Springer Science & Business Media. This book was released on 2012-12-28 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human action analysis and recognition is a relatively mature field, yet one which is often not well understood by students and researchers. The large number of possible variations in human motion and appearance, camera viewpoint, and environment, present considerable challenges. Some important and common problems remain unsolved by the computer vision community. However, many valuable approaches have been proposed over the past decade, including the motion history image (MHI) method. This method has received significant attention, as it offers greater robustness and performance than other techniques. This work presents a comprehensive review of these state-of-the-art approaches and their applications, with a particular focus on the MHI method and its variants.
Download or read book Mind in Motion written by Barbara Tversky and published by Basic Books. This book was released on 2019-05-21 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: An eminent psychologist offers a major new theory of human cognition: movement, not language, is the foundation of thought When we try to think about how we think, we can't help but think of words. Indeed, some have called language the stuff of thought. But pictures are remembered far better than words, and describing faces, scenes, and events defies words. Anytime you take a shortcut or play chess or basketball or rearrange your furniture in your mind, you've done something remarkable: abstract thinking without words. In Mind in Motion, psychologist Barbara Tversky shows that spatial cognition isn't just a peripheral aspect of thought, but its very foundation, enabling us to draw meaning from our bodies and their actions in the world. Our actions in real space get turned into mental actions on thought, often spouting spontaneously from our bodies as gestures. Spatial thinking underlies creating and using maps, assembling furniture, devising football strategies, designing airports, understanding the flow of people, traffic, water, and ideas. Spatial thinking even underlies the structure and meaning of language: why we say we push ideas forward or tear them apart, why we're feeling up or have grown far apart. Like Thinking, Fast and Slow before it, Mind in Motion gives us a new way to think about how--and where--thinking takes place.
Download or read book Human Life in Motion written by Francisco J. Gonzalez and published by Indiana University Press. This book was released on 2024-03-05 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human Life in Motion presents for the first time the previously unpublished transcripts of the seminars on Aristotle Martin Heidegger gave in the 1920s. These transcripts reveal much about the evolution of his thought during that time. Detailed student transcripts for these seminars appear among the papers of one of Heidegger's students, Helene Weiss, held today in the Special Collections Department of Stanford University. Analyzing and organizing hundreds of pages of these transcripts written by different students, Francisco Gonzalez brilliantly reconstructs the original seminars. He summarizes what Heidegger presented and claimed in each class. Gonzalez also throws into relief the overarching philosophical significance of the seminars, showing how the different interpretative moves or claims are connected and where they lead, something which in turn requires explicating them in the context of both the Aristotelian texts discussed and Heidegger's own thought during this period. Essential reading for students and scholars of Heidegger or Aristotle, Human Life in Motion is a publishing event that forces a reconsideration of the thought and legacy of both philosophers.

Download or read book Modelling Human Motion written by Nicoletta Noceti and published by Springer Nature. This book was released on 2020-07-09 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new frontiers of robotics research foresee future scenarios where artificial agents will leave the laboratory to progressively take part in the activities of our daily life. This will require robots to have very sophisticated perceptual and action skills in many intelligence-demanding applications, with particular reference to the ability to seamlessly interact with humans. It will be crucial for the next generation of robots to understand their human partners and at the same time to be intuitively understood by them. In this context, a deep understanding of human motion is essential for robotics applications, where the ability to detect, represent and recognize human dynamics and the capability for generating appropriate movements in response sets the scene for higher-level tasks. This book provides a comprehensive overview of this challenging research field, closing the loop between perception and action, and between human-studies and robotics. The book is organized in three main parts. The first part focuses on human motion perception, with contributions analyzing the neural substrates of human action understanding, how perception is influenced by motor control, and how it develops over time and is exploited in social contexts. The second part considers motion perception from the computational perspective, providing perspectives on cutting-edge solutions available from the Computer Vision and Machine Learning research fields, addressing higher-level perceptual tasks. Finally, the third part takes into account the implications for robotics, with chapters on how motor control is achieved in the latest generation of artificial agents and how such technologies have been exploited to favor human-robot interaction. This book considers the complete human-robot cycle, from an examination of how humans perceive motion and act in the world, to models for motion perception and control in artificial agents. In this respect, the book will provide insights into the perception and action loop in humans and machines, joining together aspects that are often addressed in independent investigations. As a consequence, this book positions itself in a field at the intersection of such different disciplines as Robotics, Neuroscience, Cognitive Science, Psychology, Computer Vision, and Machine Learning. By bridging these different research domains, the book offers a common reference point for researchers interested in human motion for different applications and from different standpoints, spanning Neuroscience, Human Motor Control, Robotics, Human-Robot Interaction, Computer Vision and Machine Learning. Chapter 'The Importance of the Affective Component of Movement in Action Understanding' of this book is available open access under a CC BY 4.0 license at link.springer.com.

Download or read book Dance Notations and Robot Motion written by Jean-Paul Laumond and published by Springer. This book was released on 2015-11-24 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: How and why to write a movement? Who is the writer? Who is the reader? They may be choreographers working with dancers. They may be roboticists programming robots. They may be artists designing cartoons in computer animation. In all such fields the purpose is to express an intention about a dance, a specific motion or an action to perform, in terms of intelligible sequences of elementary movements, as a music score that would be devoted to motion representation. Unfortunately there is no universal language to write a motion. Motion languages live together in a Babel tower populated by biomechanists, dance notators, neuroscientists, computer scientists, choreographers, roboticists. Each community handles its own concepts and speaks its own language. The book accounts for this diversity. Its origin is a unique workshop held at LAAS-CNRS in Toulouse in 2014. Worldwide representatives of various communities met there. Their challenge was to reach a mutual understanding allowing a choreographer to access robotics concepts, or a computer scientist to understand the subtleties of dance notation. The liveliness of this multidisciplinary meeting is reflected by the book thank to the willingness of authors to share their own experiences with others.
