Digital Color

All successful imaging systems employ some form of color management for previewing, controlling and adjusting color throughout the image-production process. Today’s increasingly complex systems pose challenging problems: they must support numerous devices and media having disparate color properties, and they also must provide for the interchange of images among dissimilar systems. In this book, the authors address and solve these problems using innovative methods of representing color in the digital domain. The second edition of this popular book explains the capabilities and limitations of existing color management systems and provides comprehensive practical solutions for communicating color within and among imaging systems, from the simplest to the most complex. Beginning with the fundamentals of color and human color perception, the book progresses to in-depth analyses of the nature of color images, digital color encoding, color management systems and digital color interchange. Fully revised and updated, this second edition of Digital Color Management features new and expanded coverage including: electronic displays and electronic imaging systems; scene-based and appearance-based color encoding methods; color management for digital cinema; a Unified Paradigm—a comprehensive, integrated color-managed environment for the color-imaging industry; four new chapters, two new appendices, and more than 80 new figures. This book is an essential resource for engineers, programmers and imaging professionals designing and engineering color-imaging systems and for others simply looking to increase their understanding of the field. Scientists, researchers, advanced undergraduates and graduate students involved in imaging technology also will find this book of significant interest and usefulness. Reviews for the first edition: ‘The absence of unnecessary jargon, the impeccable writing style, the material depth leads only to one conclusion: If you buy one digital color book this year, buy this one.’ W. David Schwaderer, Digital Camera Magazine ‘It [Digital Color Management] fulfils the need among engineers and scientists for a comprehensive understanding of color management, imaging, media, viewing conditions, appearance and communication.’ Arthur S. Diamond, Imaging News

An introduction to color in three-dimensional image processing and the emerging area of multi-spectral image processing The importance of color information in digital image processing is greater than ever. However, the transition from scalar to vector-valued image functions has not yet been generally covered in most textbooks. Now, Digital Color Image Processing fills this pressing need with a detailed introduction to this important topic. In four comprehensive sections, this book covers: The fundamentals and requirements for color image processing from a vector-valued viewpoint Techniques for preprocessing color images Three-dimensional scene analysis using color information, as well as the emerging area of multi-spectral imaging Applications of color image processing, presented via the examination of two case studies In addition to introducing readers to important new technologies in the field, Digital Color Image Processing also contains novel topics such as: techniques for improving three-dimensional reconstruction, three-dimensional computer vision, and emerging areas of safety and security applications in luggage inspection and video surveillance of high-security facilities. Complete with full-color illustrations and two applications chapters, Digital Color Image Processing is the only book that covers the breadth of the subject under one convenient cover. It is written at a level that is accessible for first- and second-year graduate students in electrical and computer engineering and computer science courses, and that is also appropriate for researchers who wish to extend their knowledge in the area of color image processing.

The vast majority of modern criminal investigations involve some element of digital evidence, from mobile phones, computers, CCTV and other devices. Digital Forensics: Digital Evidence in Criminal Investigations provides the reader with a better understanding of how digital evidence complements “traditional” scientific evidence and examines how it can be used more effectively and efficiently in a range of investigations. Taking a new approach to the topic, this book presents digital evidence as an adjunct to other types of evidence and discusses how it can be deployed effectively in support of investigations. The book provides investigators/SSMs/other managers with sufficient contextual and technical information to be able to make more effective use of digital evidence sources in support of a range of investigations. In particular, it considers the roles played by digital devices in society and hence in criminal activities. From this, it examines the role and nature of evidential data which may be recoverable from a range of devices, considering issues relating to reliability and usefulness of those data. Includes worked case examples, test questions and review quizzes to enhance student understanding Solutions provided in an accompanying website Includes numerous case studies throughout to highlight how digital evidence is handled at the crime scene and what can happen when procedures are carried out incorrectly Considers digital evidence in a broader context alongside other scientific evidence Discusses the role of digital devices in criminal activities and provides methods for the evaluation and prioritizing of evidence sources Includes discussion of the issues surrounding modern digital evidence examinations, for example; volume of material and its complexity Clear overview of all types of digital evidence Digital Forensics: Digital Evidence in Criminal Investigations is an invaluable text for undergraduate students taking either general forensic science courses where digital forensics may be a module or a dedicated computer/digital forensics degree course. The book is also a useful overview of the subject for postgraduate students and forensic practitioners.
