Available in PDF, EPUB and Kindle. Book excerpt: Video context analysis is an active and vibrant research area, which provides means for extracting, analyzing and understanding behavior of a single target and multiple targets. Over the last few decades, computer vision researchers have been working to improve the accuracy and robustness of algorithms to analyse the context of a video automatically. In general, the research work in this area can be categorized into three major topics: 1) counting number of people in the scene 2) tracking individuals in a crowd and 3) understanding behavior of a single target or multiple targets in the scene. This book focusses on tracking individual targets and detecting abnormal behavior of a crowd in a complex scene. Firstly, this book surveys the state-of-the-art methods for tracking multiple targets in a complex scene and describes the authors' approach for tracking multiple targets. The proposed approach is to formulate the problem of multi-target tracking as an optimization problem of finding dynamic optima (pedestrians) where these optima interact frequently. A novel particle swarm optimization (PSO) algorithm that uses a set of multiple swarms is presented. Through particles and swarms diversification, motion prediction is introduced into the standard PSO, constraining swarm members to the most likely region in the search space. The social interaction among swarm and the output from pedestrians-detector are also incorporated into the velocity-updating equation. This allows the proposed approach to track multiple targets in a crowded scene with severe occlusion and heavy interactions among targets. The second part of this book discusses the problem of detecting and localising abnormal activities in crowded scenes. We present a spatio-temporal Laplacian Eigenmap method for extracting different crowd activities from videos. This method learns the spatial and temporal variations of local motions in an embedded space and employs representatives of different activities to construct the model which characterises the regular behavior of a crowd. This model of regular crowd behavior allows for the detection of abnormal crowd activities both in local and global context and the localization of regions which show abnormal behavior.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, computer vision researchers have been working to improve the accuracy and robustness of algorithms for the context analysis of videos capturing single or multiple moving targets. However, devising algorithms that can work in uncontrolled environments with variable and unfavourable lighting conditions is still a major challenge. This thesis aims to develop robust methodologies to analyse scenes with multiple moving targets captured by a stationary camera. First, a new particle swarm optimisation algorithm is proposed to in-corporate social interaction among targets. A set of interactive swarms is employed to track multiple pedestrians in a crowd. The proposed method improves the standard particle swarm optimisation algorithm with a dynamic social model that enhances the interaction among swarms. In addition, constraints provided by temporal continuity and strength of person detections are incorporated in the tracking process. This allows the particle swarm optimisation algorithm to track multiple moving targets in a complex scene. Second, a novel method is proposed to detect global unusual events and accurately localise abnormal regions in the monitored scene. The idea is to exploit temporal coherence between video frames and use the manifold learning algorithm, in particular Laplacian Eigenmaps, to discover different crowd activities from a video. The proposed method provides an advantage of visualising and identifying different crowd events in a low dimensional space and detect abnormality. Then, this method is further extended to detect localised abnormality where the behaviour of an individual deviates from the rest of the crowd. In this approach. the visual contexts of multiple local patches are studied to model the regular behaviour of a crowded scene. This local probabilistic model allows to detect abnormal behaviour in both local and global context and localise the regions where abnormal behaviour occurs. The performance of the proposed algorithms is validated using standard data-sets and surveillance videos captured in uncontrolled environments.
Download or read book The Discourse of YouTube written by Phil Benson and published by Routledge. This book was released on 2016-10-26 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Discourse of YouTube explores the cutting edge of contemporary multimodal discourse through an in-depth analysis of structures, processes and content in YouTube discourse. YouTube is often seen as no more than a place to watch videos, but this book argues that YouTube and YouTube pages can also be read and analysed as complex, multi-authored, multimodal texts, emerging dynamically from processes of textually-mediated social interaction. The objective of the book is to show how multimodal discourse analysis tools can help us to understand the structures and processes involved in the production of YouTube texts. Philip Benson develops a framework for the analysis of multimodality in the structure of YouTube pages and of the multimodal interactions from which their content emerges. A second, and equally important, objective is to show how the globalization of YouTube is central to much of its discourse. The book identifies translingual practice as a key element in the global discourse of YouTube and discusses its roles in the negotiation of identities and intercultural learning in videos and comments. Focusing on YouTube as a key example of new digital media, The Discourse of YouTube makes a substantial contribution to conversations about new ways of producing multimodal text in a digital world.

Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, instance-level video analysis has been approached in a bottom-up strategy, where high-level instance-specific information is estimated from low-level features which correspond to the target instance. While instance-level approaches have shown success and several state-of-the-art methods are based on such strategies [70, 11, 133, 112, 144], we argue that this a sub-optimal strategy to approach the problem of instance-level video analysis. In this work we focus on the discovery and modeling of useful contextual information, along with the methods required to integrate local and contextual information, which ultimately allows us to better approach instance-level problems. This thesis focuses on two related tasks of video instance analysis: classification and segmentation. In the domain of video segmentation, we introduce the "Multi-Attention Instance Network" (MAIN) an instance-level approach which is the first to directly model and integrate multiple segmentation targets in the domain of one-shot video segmentation. MAIN fuses long-term, and short-term visual cues for simultaneous segmentation targets...

Download or read book Evolution and Contextual Behavioral Science written by David Sloan Wilson and published by New Harbinger Publications. This book was released on 2018-09-01 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: What do evolutionary science and contextual behavioral science have in common? Edited by David Sloan Wilson and Steven C. Hayes, this groundbreaking book offers a glimpse into the histories of these two schools of thought, and provides a sound rationale for their reintegration. Evolutionary science (ES) provides a unifying theoretical framework for the biological sciences, and is increasingly being applied to the human-related sciences. Meanwhile, contextual behavioral science (CBS) seeks to understand the history and function of human behavior in the context of everyday life where behaviors occur, and to influence behavior in a practical sense. This volume seeks to integrate these two bodies of knowledge that have developed largely independently. In Evolution and Contextual Behavioral Science, two renowned experts in their fields argue why ES and CBS are intrinsically linked, as well as why their reintegration—or, reunification—is essential. The main purpose of this book is to continue to move CBS under the umbrella of ES, and to help evolutionary scientists understand how working alongside contextual behavioral scientists can foster both the development of ES principles and their application to practical situations. Rather than the sequential relationship that is typically imagined between these two schools of thought, this volume envisions a parallel relationship between ES and CBS, where science can best influence positive change in the real world.

Download or read book Modeling Social and Temporal Context for Video Analysis written by Zhen Qin and published by . This book was released on 2015 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ubiquity of videos requires effective content extraction tools to enable practical applications automatically. Computer vision research focuses on bridging the gap between raw data (pixel values) and video semantics, but information based only on image values are not sufficient, due to the visual ambiguities caused by varied camera characteristics, frequent occlusions, low resolution, large intra-class and small inter-class variation among object/activity/event classes, etc.
Download or read book Context and Method in Qualitative Research written by Gale Miller and published by SAGE. This book was released on 1997-06-11 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical examination of the principles and practice of qualitative research is provided in this book which examines the interplay between context and method, making it invaluable for both the experienced and the beginning researcher. A range of methodological and practical issues central to the concerns of qualitative researchers are addressed. These include: the validity and plausibility of qualitative methods; the problems encountered using specific techniques in a range of social settings; and the moral issues raised in qualitative research. These themes are related to practical issues which are illustrated by a breadth of examples and in-depth case studies. The contributors look at the methods and strategies that they have used to study everyday life, and make suggestions to readers on why and how they might conduct their own studies. They raise issues that go beyond `cookbook' discussions of issues such as how to enter social settings, manage the subjects of one's research and ask `good' questions in the process of formulating research strategies. These issues are addressed within the framework of the larger purposes and uses of qualitative research where specific methodological problems are not used as ends in themselves.

Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Handbooks of Political Science is a ten-volume set of reference books offering authoritative and engaging critical overviews of the state of political science. Each volume focuses on a particular part of the discipline, with volumes on Public Policy, Political Theory, Political Economy, Contextual Political Analysis, Comparative Politics, International Relations, Law and Politics, Political Behavior, Political Institutions, and Political Methodology. The project as a whole is under the General Editorship of Robert E. Goodin, with each volume being edited by a distinguished international group of specialists in their respective fields. The books set out not just to report on the discipline, but to shape it. The series will be an indispensable point of reference for anyone working in political science and adjacent disciplines. The Oxford Handbook of Contextual Political Analysis sets out to synthesize and critique for the first time those approaches to political science that offer a more fine-grained qualitative analysis of the political world. The work in the volume has a common aim in being sensitive to the thoughts of contextual nuances that disappear from large-scale quantitative modelling or explanations based on abstract, general, universal laws of human behavior. It shows that 'context matters' in a great many ways: philosophical context matters; psychological context matters; cultural and historical contexts matter; place, population, and technology all matter. By showcasing scholars who specialize in the analysis of all these contexts side-by-side, the Oxford Handbook of Contextual Political Analysis shows how political scientists can take those crucial contextual factors systematically into account.
