This book presents novel hybrid encryption algorithms that possess many different characteristics. In particular, "Hybrid Encryption Algorithms over Wireless Communication Channels", examines encrypted image and video data for the purpose of secure wireless communications. A study of two different families of encryption schemes are introduced: namely, permutation-based and diffusion-based schemes. The objective of the book is to help the reader selecting the best suited scheme for the transmission of encrypted images and videos over wireless communications channels, with the aid of encryption and decryption quality metrics. This is achieved by applying number-theory based encryption algorithms, such as chaotic theory with different modes of operations, the Advanced Encryption Standard (AES), and the RC6 in a pre-processing step in order to achieve the required permutation and diffusion. The Rubik's cube is used afterwards in order to maximize the number of permutations. Transmission of images and videos is vital in today's communications systems. Hence, an effective encryption and modulation schemes are a must. The author adopts Orthogonal Frequency Division Multiplexing (OFDM), as the multicarrier transmission choice for wideband communications. For completeness, the author addresses the sensitivity of the encrypted data to the wireless channel impairments, and the effect of channel equalization on the received images and videos quality. Complete simulation experiments with MATLAB (R) codes are included. The book will help the reader obtain the required understanding for selecting the suitable encryption method that best fulfills the application requirements.
The Ottawa International Animation Festival (OIAF) began in 1976 and stands today as one of the oldest and largest animation events in the world. One of the unique features of the OIAF is the inclusion of commissioned writings that provide attendees with a more in-depth background into the festival's special screenings. These writings have not only contextualized the festival presentations but have also contributed significantly to animation education and scholarship. The Corners are Glowing is a selection of the best writings (many unseen for decades) culled from past OIAF catalogues. These wide-ranging texts cover the spectrum of animation from the familiar (Daffy Duck, Pee Wee Herman, Bob Clampett, Joanna Quinn, Hiyao Miyazaki, Frank Tashlin) to the more esoteric (Robert Breer, Emily Pelstring, Taku Furukawa, Michael Sporn, and even the use of furniture in animation!). The Corners are Glowing is a valuable time capsule that celebrates animation's past and present, and the styles of writing are as diverse, enlightening, and fun as the animation subjects being written about.
Motivated by a variational model concerning the depth of the objects in a picture and the problem of hidden and illusory contours, this book investigates one of the central problems of computer vision: the topological and algorithmic reconstruction of a smooth three dimensional scene starting from the visible part of an apparent contour. The authors focus their attention on the manipulation of apparent contours using a finite set of elementary moves, which correspond to diffeomorphic deformations of three dimensional scenes. A large part of the book is devoted to the algorithmic part, with implementations, experiments, and computed examples. The book is intended also as a user's guide to the software code appcontour, written for the manipulation of apparent contours and their invariants. This book is addressed to theoretical and applied scientists working in the field of mathematical models of image segmentation.

The chapters in this collection explore hybrid making, hybrid subjects, and hybrid spaces, generating interesting conversations about the past, current and future nature of hybrid play. Together, the authors offer important insights into how place and space are co-constructed through play; how, when, and for what reasons people occupy hybrid spaces; and how cultural practices shape elements of play and vice versa. A diverse group of scholars and practitioners provides a rich interdisciplinary perspective, which will be of great interest to those working in the areas of games studies, media studies, communication, gender studies, and media arts.
The Paradox of Transgression in Games looks at transgressive games as an aesthetic experience, tackling how players respond to game content that shocks, disturbs, and distresses, and how contemporary video games can evoke intense emotional reactions. The book delves into the commercial success of many controversial videogames: although such games may appear shocking for the observing bystander, playing them is experienced as deeply rewarding for the player. Drawing on qualitative player studies and approaches from media aesthetics theory, the book challenges the perception of games as innocent entertainment, and examines the range of emotional, moral, and intellectual experiences of players. As they explore what players consider transgressive, the authors ask whether there is something about the gameplay situation that works to mitigate the sense of transgression, stressing gameplay as an aesthetic experience. Anchoring the aesthetic game experience both in play studies as well as in aesthetic theory, this book will be an essential resource for scholars and students of game studies, aesthetics, media studies, philosophy of art, and emotions.

Group and Crowd Behavior for Computer Vision provides a multidisciplinary perspective on how to solve the problem of group and crowd analysis and modeling, combining insights from the social sciences with technological ideas in computer vision and pattern recognition. The book answers many unresolved issues in group and crowd behavior, with Part One providing an introduction to the problems of analyzing groups and crowds that stresses that they should not be considered as completely diverse entities, but as an aggregation of people. Part Two focuses on features and representations with the aim of recognizing the presence of groups and crowds in image and video data. It discusses low level processing methods to individuate when and where a group or crowd is placed in the scene, spanning from the use of people detectors toward more ad-hoc strategies to individuate group and crowd formations. Part Three discusses methods for analyzing the behavior of groups and the crowd once they have been detected, showing how to extract semantic information, predicting/tracking the movement of a group, the formation or disaggregation of a group/crowd and the identification of different kinds of groups/crowds depending on their behavior. The final section focuses on identifying and promoting datasets for group/crowd analysis and modeling, presenting and discussing metrics for evaluating the pros and cons of the various models and methods. This book gives computer vision researcher techniques for segmentation and grouping, tracking and reasoning for solving group and crowd modeling and analysis, as well as more general problems in computer vision and machine learning.

Locating Imagination in Popular Culture offers a multi-disciplinary account of the ways in which popular culture, tourism and notions of place intertwine in an environment characterized by ongoing processes of globalization, digitization and an increasingly ubiquitous nature of multi-media. Centred around the concept of imagination, the authors demonstrate how popular culture and media are becoming increasingly important in the ways in which places and localities are imagined, and how they also subsequently stimulate a desire to visit the actual places in which people's favourite stories are set. With examples drawn from around the globe, the book offers a unique study of the role of narratives conveyed through media in stimulating and reflecting desire in tourism. This book will have appeal in a wide variety of academic disciplines, ranging from media and cultural studies to fan- and tourism studies, cultural geography, literary studies and cultural sociology.

This book offers critical perspectives on the digital 'iconic', exploring how the notion of the iconic is re-appropriated and re-made online, and the consequences for humanity and society. Examining cross-cultural case studies of iconic images in digital spaces, the author offers original and critical analyses, theories and perspectives on the notion of the 'iconic', and on its movement, re-appropriation and meaning making on digital platforms. A carefully curated selection of case studies illustrates topics such as phantom memory; martyrdom; denigration and pornographic recoding; digital games as simulacra; and memes as 'artification'. Situating the notion of the iconic firmly within contemporary cultures, the author takes a thematic approach to investigate the iconic as an unstable and unfinished phenomenon online as it travels through platforms temporally and spatially. The book will be an important resource for academics and students in the areas of media and communications, digital culture, cultural studies, visual communication, visual culture, journalism studies and digital humanities.
Independent Videogames investigates the social and cultural implications of contemporary forms of independent video game development. Through a series of case studies and theoretical investigations, it evaluates the significance of such a multi-faceted phenomenon within video game and digital cultures. A diverse team of scholars highlight the specificities of independence within the industry and the culture of digital gaming through case studies and theoretical questions. The chapters focus on labor, gender, distribution models and technologies of production to map the current state of research on independent game development. The authors also identify how the boundaries of independence are becoming opaque in the contemporary game industry - often at the cost of the claims of autonomy, freedom and emancipation that underlie the indie scene. The book ultimately imagines new and better narratives for a less exploitative and more inclusive videogame industry. Systematically mapping the current directions of a phenomenon that is becoming increasingly difficult to define and limit, this book will be a crucial resource for scholars and students of game studies, media history, media industries and independent gaming.

This book presents the latest technological advances and practical tools for discovering, verifying and visualizing social media video content, and managing related rights. The digital media revolution is bringing breaking news to online video platforms, and news organizations often rely on user-generated recordings of new and developing events shared in social media to illustrate the story. However, in video, there is also deception. In today's "fake news" era, access to increasingly sophisticated editing and content management tools and the ease with which fake information spreads in electronic networks, require the entire news and media industries to carefully verify third-party content before publishing it. As such, this book is of interest to computer scientists and researchers, news and media professionals, as well as policymakers and data-savvy media consumers.
Data has emerged as a key component that determines how interactions across the world are structured, mediated and represented. This book examines these new data publics and the areas in which they become operative, via analysis of politics, geographies, environments and social media platforms. By claiming to offer a mechanism to translate every conceivable occurrence into an abstract code that can be endlessly manipulated, digitally processed data has caused conventional reference systems which hinge on our ability to mark points of origin, to rapidly implode. Authors from a range of disciplines provide insights into such a political economy of data capitalism; the political possibilities of techno-logics beyond data appropriation and data refusal; questions of visual, spatial and geographical organization; emergent ways of life and the environments that sustain them; and the current challenges of data publics, which is explored via case studies of three of the most influential platforms in the social media economy today: Facebook, Instagram and Whatsapp. Data Publics will be of great interest to academics and students in the fields of computer science, philosophy, sociology, media and communication studies, architecture, visual culture, art and design, and urban and cultural studies.
Digital art practitioners work under the constant threat of a medium - the digital - that objectifies the self and depersonalises artistic identities. If digital technology is a pharmakon in that it can be either cure or poison, with regard to digital art practices the digital may have in fact worked as a placebo that has allowed us to push back the date in which the crisis between digital and art will be given serious thought. This book is hence concerned with an analysis of such a relationship and proposes their rethinking in terms of an ethico-phenomenological practice informed by an in-depth understanding of the digital medium. Giuseppe Torre engages with underground cultures such as Free and Libre Open Source Software (FLOSS) and its ties with art discourse. The discussion is informed by various philosophical discourses and media theories, with a focus on how such ideas connect back to the existing literature in performance studies. Replete with examples of artwork and practices, this book will be of great interest to students and scholars of theatre and performance studies, art and technology.
