Visualizing the Data City
Paolo Ciuccarelli, Giorgia Lupi, Luca Simeone
This book investigates novel methods and technologies for the collection, analysis, and representation of real-time user-generated data at the urban scale in order to explore potential scenarios for more participatory design, planning, and management processes. For this purpose, the authors present a set of experiments conducted in collaboration with urban stakeholders at various levels (including citizens, city administrators, urban planners, local industries, and NGOs) in Milan and New York in 2012. It is examined whether geo-tagged and user-generated content can be of value in the creation of meaningful, real-time indicators of urban quality, as it is perceived and communicated by the citizens. The meanings that people attach to places are also explored to discover what such an urban semantic layer looks like and how it unfolds over time. As a conclusion, recommendations are proposed for the exploitation of user-generated content in order to answer hitherto unsolved urban questions. Readers will find in this book a fascinating exploration of techniques for mining the social web that can be applied to procure user-generated content as a means of investigating urban dynamics.
Visualizing Sustainable Planning
Gerhard Steinebach, Subhrajit Guhathakurta, Hans Hagen
This volume presents the state of the art in the rapidly growing field of visualization as related to problems in urban and regional planning. It brings together a rich compendium of visualization tools.
Visual Cryptography for Image Processing and Security
Feng Liu, Wei Qi Yan
This unique book describes the fundamental concepts, theories and practice of visual cryptography. The design, construction, analysis, and application of visual cryptography schemes (VCSs) are discussed in detail. Original, cutting-edge research is presented on probabilistic, size invariant, threshold, concolorous, and cheating immune VCS. Features: provides a thorough introduction to the field; examines various common problems in visual cryptography, including the alignment, flipping, cheating, distortion, and thin line problems; reviews a range of VCSs, including XOR-based visual cryptography and security enriched VCS; describes different methods for presenting color content using visual cryptographic techniques; covers such applications of visual cryptography as watermarking, resolution variant VCS, and multiple resolution VCS. This logically-structured and comprehensive work will serve as a helpful reference for all researchers and students interested in document authentication and cryptography.
Visual Analysis of Humans
Thomas B. Moeslund, Adrian Hilton, Volker Krüger, Leonid Sigal
Understanding human activity from video is a key problem in the field of computer vision. With broad coverage and an accessible style, this unique reference is a coherent and comprehensive view of all aspects of the video analysis of humans and their actions.
