• Sommario/riassunto: Medievalists reading and writing about and around authority-related themes lack clear definitions of its actual meanings in the medieval context. Authorities in the Middle Ages offers answers to this thorny issue through specialized investigations. This book considers the concept of authority and explores the various practices of creating authority in medieval society. In their studies sixteen scholars investigate the definition, formation, establishment, maintenance, and collapse of what we understand in terms of medieval struggles for authority, influence and power. The interdisciplinary nature of this volume resonates with the multi-faceted field of medieval culture, its social structures, and forms of communication. The fields of expertise include history, legal studies, theology, philosophy, politics, literature and art history. The scope of inquiry extends from late antiquity to the mid-fifteenth century, from the Church Fathers debating with pagans to the rapacious ghosts ruining the life of the living in the Sagas. There is a special emphasis on such exciting but understudied areas as the Balkans, Iceland and the eastern fringes of Scandinavia.

• Sommario/riassunto: A central issue in computer vision is the problem of signal to symbol transformation. In the case of texture, which is an important visual cue, this problem has hitherto received very little attention. This book presents a solution to the signal to symbol transformation problem for texture. The symbolic de- scription scheme consists of a novel taxonomy for textures, and is based on appropriate mathematical models for different kinds of texture. The taxonomy classifies textures into the broad classes of disordered, strongly ordered, weakly ordered and compositional. Disordered textures are described by statistical mea- sures, strongly ordered textures by the placement of primitives, and weakly ordered textures by an orientation field. Compositional textures are created from these three classes of texture by using certain rules of composition. The unifying theme of this book is to provide standardized symbolic descriptions that serve as a descriptive vocabulary for textures. The algorithms developed in the book have been applied to a wide variety of textured images arising in semiconductor wafer inspection, flow visualization and lumber processing. The taxonomy for texture can serve as a scheme for the identification and description of surface flaws and defects occurring in a wide range of practical applications.
