Digital Media has transformed the way Canadians socialize and interact, conduct business, experience culture, fight political battles, and acquire knowledge. Traditional media, including newspapers and conventional TV networks, remain the primary link to Canada's political sphere but are under concerted attack. YouTube, blogs, online broadcasting, Facebook, and Twitter have opened new and exciting avenues of expression but offer little of the same "nation-building glue" as traditional media. Consequently, Canada is experiencing a number of overlapping crises simultaneously: a crisis in news and journalism, threats to the survival of the media system as a whole, and a decline in citizen engagement. In Digital Mosaic, David Taras both embraces and challenges new media by arguing that these coinciding crises bring exciting opportunities as well as considerable dangers to democratic life and citizen engagement in Canada.

Through the works of cutting-edge computer artists, composers, and designers, DIGITAL MOSAICS explores the possibilities of the digital medium and how it radically transforms the way art is produced and understood by the audience. Digital expert Steven Holtzman lays the groundwork for the digital and art worlds of our future. Index. 86 illustrations.

This edition presents the most prominent topics and applications of digital image processing, analysis, and computer graphics in the field of cultural heritage preservation. The text assumes prior knowledge of digital image processing and computer graphics fundamentals. Each chapter contains a table of contents, illustrations, and figures that elucidate the presented concepts in detail, as well as a chapter summary and a bibliography for further reading. Well-known experts cover a wide range of topics and related applications, including spectral imaging, automated restoration, computational reconstruction, digital reproduction, and 3D models.

The digital world has impacted the way Canadians socialize and interact with others, teach and learn, conduct business, experience culture, fight political battles, and acquire knowledge. The traditional forms of media, newspapers, radio, and television are being replaced by digital media which is fast, sporadic, and sometimes inaccurate. As a result, Canada is experiencing a number of overlapping crises simultaneously: a crisis in traditional media, a crisis in public broadcasting, a crisis in news and journalism, and a crisis in citizen engagement.

Designed for an introductory course in remote sensing, this highly regarded text offers 28 pages with color photos, Sabins trademark clarity, and comprehensive coverage. The first chapter vividly introduces the major remote sensing systems and the interactions between electromagnetic energy and materials that are the basis for remote sensing. Six following chapters describe the major imaging systems. After a digital image-processing chapter, Sabins devotes the rest of the text to descriptions of practical applications of remote sensing to environmental monitoring, oil and mineral exploration, land-use and geographic information systems, and natural hazards.
