Abstract

Real-Time Video Compression: Techniques and Algorithms introduces the XYZ video compression technique, which operates in three dimensions, eliminating the overhead of motion estimation. First, video compression standards, MPEG and H.261/H.263, are described. They both use asymmetric compression algorithms, based on motion estimation. Their encoders are much more complex than decoders. The XYZ technique uses a symmetric algorithm, based on the Three-Dimensional Discrete Cosine Transform (3D-DCT). 3D-DCT was originally suggested for compression about twenty years ago; however, at that time the computational complexity of the algorithm was too high, it required large buffer memory, and was not as effective as motion estimation. We have resurrected the 3D-DCT-based video compression algorithm by developing several enhancements to the original algorithm. These enhancements make the algorithm feasible for real-time video compression in applications such as video-on-demand, interactive multimedia, and videoconferencing. The demonstrated results, presented in this book, suggest that the XYZ video compression technique is not only a fast algorithm, but also provides superior compression ratios and high quality of the video compared to existing standard techniques, such as MPEG and H.261/H.263. The elegance of the XYZ technique is in its simplicity, which leads to inexpensive VLSI implementation of any XYZ codec. Real-Time Video Compression: Techniques and Algorithms can be used as a text for graduate students and researchers working in the area of real-time video compression. In addition, the book serves as an essential reference for professionals in the field.

Abstract

The ease of access, relative anonymity, and borderless nature of the Internet has allowed widespread computer-based crime – or cybercrime – to proliferate rapidly. Law enforcement and international security organizations, along with governments and the private sector, have only recently begun to appreciate the scope, severity and transnational nature of this problem. In recent years, organizations have begun to emerge and evolve in a progressively collaborative ecosystem of vested international bodies seeking to address these challenges in unique, innovative ways. This study attempts to address a series of questions regarding the current state of cyber security. What does the international landscape of cyber security look like today? What are these organizations actually doing? Are they succeeding? What measureable progress has been made in developing a supportive ecosystem of global cyber security? Are these organizations presenting practical, innovative, collaborative, and sustainable solutions to address these issues? Global Initiatives to Secure Cyberspace: An Emerging Landscape is designed for a professional audience composed of researchers, practitioners and the government, focusing on a secure cyberspace industry. Advanced-level students in computer science will also find this book suitable. .
