This book offers a comprehensive introduction in to the various theories of colour and how they developed over the centuries and millennia. As colour is the perception of light by our brains, the book captures not only the physical phenomena but also psychological and philosophical aspects of colours.

The CAA-GR 2024 Conference Proceedings capture the spirit and substance of the fifth national meeting on computer applications in archaeology and cultural heritage, held in Serres, Greece. Organized by the Athena Research Center and the International Hellenic University, the conference brought together a vibrant community of researchers, professionals, and practitioners exploring how digital technologies are reshaping our relationship and interaction with the past.Under the theme “Transforming Heritage Research in a Transforming World,” the volume reflects the urgent need for new approaches to the study and preservation of cultural heritage in the face of rapid technological advances, environmental challenges, and societal shifts. The chapters span a wide range of topics—from geophysical methods and risk management to 3D scanning, immersive visualization, digital tourism, and museum accessibility—highlighting the interdisciplinary and forward-thinking spirit that defines the field today. Rich with innovative ideas, practical solutions, and theoretical reflections, this volume offers a compelling look at how computational tools are redefining the boundaries of archaeology and heritage studies. It is an essential resource for anyone interested in the digital transformation of the cultural sector and the future of heritage research.

This book presents the main concepts in handling digital images of mixed content, traditionally referenced as mixed raster content (MRC), in two main parts. The first includes introductory chapters covering the scientific and technical background aspects, whereas the second presents a set of research and development approaches to tackle key issues in MRC segmentation, compression and transmission.The book starts with a review of color theory and the mechanism of color vision in humans. In turn, the second chapter reviews data coding and compression methods so as to set the background and demonstrate the complexity involved in dealing with MRC. Chapter three addresses the segmentation of images through an extensive literature review, which highlights the various approaches used to tackle MRC segmentation.The second part of the book focuses on the segmentation of color images for optimized compression, including multi-layered decomposition and representation of MRCand the processes that can be employed to optimize the coding rates of those different layers. Rounding out the coverage, the final chapter examines the segmentation of color images for optimized transmission.
