Visual perception is a complex process requiring interaction between the receptors in the eye that sense the stimulus and the neural system and the brain that are responsible for communicating and interpreting the sensed visual information. This process involves several physical, neural, and cognitive phenomena whose understanding is essential to design effective and computationally efficient imaging solutions. Building on advances in computer vision, image and video processing, neuroscience, and information engineering, perceptual digital imaging greatly enhances the capabilities of traditional imaging methods. Filling a gap in the literature, Perceptual Digital Imaging: Methods and Applications comprehensively covers the system design, implementation, and application aspects of this emerging specialized area. It gives readers a strong, fundamental understanding of theory and methods, providing a foundation on which solutions for many of the most interesting and challenging imaging problems can be built. The book features contributions by renowned experts who present the state of the art and recent trends in image acquisition, processing, storage, display, and visual quality evaluation. They detail advances in the field and explore human visual system-driven approaches across a broad spectrum of applications, including: Image quality and aesthetics assessment Digital camera imaging White balancing and color enhancement Thumbnail generation Image restoration Super-resolution imaging Digital halftoning and dithering Color feature extraction Semantic multimedia analysis and processing Video shot characterization Image and video encryption Display quality enhancement This is a valuable resource for readers who want to design and implement more effective solutions for cutting-edge digital imaging, computer vision, and multimedia applications. Suitable as a graduate-level textbook or stand-alone reference for researchers and practitioners, it provides a unique overview of an important and rapidly developing research field.
Youth development is as a core aspect of human and national progress in Nigeria. The study suggests the development of young people as the means of poverty reduction. It indicates that amidst cultural, ethnic, and religious diversities, and in the light of threats to human life and property, the development of the youth is the way to promoting peace and unity, justice, and security. The book argues on a two-fold contribution: While the Nigerian Church is to intensify efforts in the active participation of lay Christians in politics, the State is to tackle critical areas to ensure a decent standard of living for all.
"Iroquois treaty-making has had enormous significance in American history, even to the present day. But until now, we have not had a comprehensive collection of treaty documents and systematic study of the Iroquois treaty procedure. This book brings the research of negotiations carried on by the Dutch, English, French, and Americans with the Iroquois to a new level of sophistication. Since September 1978, the D'Arcy McNickle Center for the History of the American at Chicago's Newberry Library has directed a project funded by the National Endowment for the Humanities to compile and publish a documentary history of the Iroquois. The results of this undertaking are: (1) a comprehensive microform corpus of Iroquois treaties and related documents, (2) a printed calendar and index to the treaties, and (3) this reference guide to the treaties and their meanings. In addition to summary essays by Francis Jennings on history and background, William N. Fenton on Culture, Mary A. Drake on structure, Robert J. Surtees on Canada, and Michael K. Foster on linguistics, the editors have included a sample treaty with analytical commentary. They have drawn together a list of participants in Iroquois treaties, figures of speech in political rhetoric, a gazetteer of place names and their modern equivalents, maps of areas important to treaty-making, a descriptive treaty calendar listing negotiations involving Iroquois Indians 1613-1913, and a select bibliography. This books makes the rich array of treaty documents accessible to the informed lay reader. Its publication is a landmark in Iroquois studies." -- Publisher's description
