The successful cooperation of the Varaždin City Museum and the Department of Paper and Leather of the Croatian Conservation Institute has resulted in a large number of restored prints rescued from ...further decay. Each of them can now be presented and shown as deserved. From year to year, approximately ten prints are restored annually according to a systematic plan. This is an extremely valuable and important cooperation for the Varaždin City Museum. The paper (Part 1) deals with a brief overview of the Collection of paintings, sculptures, prints and drawings the significant part of which are the prints. The presentation and the description of the most important selected prints that make up the basis of the highly valuable prints in the Museum are described. Within the years of a successful cooperation between the Department for Paper and Leather and the Varaždin City Museum a large number of significant artworks on paper have been restored. Two Japanese woodblock prints from the 18th century are the highlights. The author of these woodblocks is the Japanese master Eishi Hosoda (1756-1829).

This book presents a substantial description of the principles and applications of digital holography. The first part of the book deals with mathematical basics and the linear filtering theory ...necessary to approach the topic. The next part describes the fundamentals of diffraction theory and exhaustively details the numerical computation of diffracted fields using FFT algorithms. A thorough presentation of the principles of holography and digital holography, including digital color holography, is proposed in the third part. A special section is devoted to the algorithms and methods for the numerical reconstruction of holograms. There is also a chapter devoted to digital holographic interferometry with applications in holographic microscopy, quantitative phase contrast imaging, multidimensional deformation investigations, surface shape measurements, fluid mechanics, refractive index investigations, synthetic aperture imaging and information encrypting. Keys so as to understand the differences between digital holography and speckle interferometry and examples of software for hologram reconstructions are also treated in brief.Contents1. Mathematical Prerequisites. 2. The Scalar Theory of Diffraction. 3. Calculating Diffraction by Fast Fourier Transform. 4. Fundamentals of Holography. 5. Digital Off-Axis Fresnel Holography. 6. Reconstructing Wavefronts Propagated through an Optical System. 7. Digital Holographic Interferometry and Its Applications. Appendix. Examples of Digital Hologram Reconstruction Programs
Assembling contributions from experienced developers, vendors, researchers, and educators, OpenGL Insights presents real-world techniques for intermediate and advanced OpenGL, OpenGL ES, and WebGL ...developers. Focusing on current and emerging techniques for the OpenGL family of APIs, the book demonstrates the breadth and depth of OpenGL. Readers will gain practical skills to solve problems related to performance, rendering, profiling, framework design, and more. Source code, demos, and other material are available on the book's website.
Computer graphics systems are capable of generating stunningly realistic images of objects that have never physically existed. In order for computers to create these accurately detailed images, ...digital models of appearance must include robust data to give viewers a credible visual impression of the depicted materials. In particular, digital models demonstrating the nuances of how materials interact with light are essential to this capability. Digital Modeling of Material Appearance is the first comprehensive work on the digital modeling of material appearance: it explains how models from physics and engineering are combined with keen observation skills for use in computer graphics rendering. Written by the foremost experts in appearance modeling and rendering, this book is for practitioners who want a general framework for understanding material modeling tools, and also for researchers pursuing the development of new modeling techniques. The text is not a "how to" guide for a particular software system. Instead, it provides a thorough discussion of foundations and detailed coverage of key advances. Practitioners and researchers in applications such as architecture, theater, product development, cultural heritage documentation, visual simulation and training, as well as traditional digital application areas such as feature film, television, and computer games, will benefit from this much needed resource. ABOUT THE AUTHORS Julie Dorsey and Holly Rushmeier are professors in the Computer Science Department at Yale University and co-directors of the Yale Computer Graphics Group. François Sillion is a senior researcher with INRIA (Institut National de Recherche en Informatique et Automatique), and director of its Grenoble Rhône-Alpes research center. * First comprehensive treatment of the digital modeling of material appearance * Provides a foundation for modeling appearance, based on the physics of how light interacts with materials, how people perceive appearance, and the implications of rendering appearance on a digital computer * An invaluable, one-stop resource for practitioners and researchers in a variety of fields dealing with the digital modeling of material appearance
Focusing on graphic user interfaces (GUIs) within the R language, this book shows programmers and users how to develop their own GUIs, enabling them to interface with other languages. The text opens ...the possibilities of R's huge and growing set of statistical methods. The authors cover four different packages for writing GUIs: gWidgets, RGtk2, Qt, and Tcl Tk. Supported by a package in CRAN that contains all of the code along with additional examples, the text is filled with numerous examples ranging from the very simple to detailed illustrations of how to code actual interfaces.
Upliv novih medija (najprije onih utemeljenih na digitalnim postupcima proizvodnje i distribucije slike) u umjetničko stvaralaštvo imao je osjetan efekt, posebno na grafičku umjetnost. Novi mediji u ...grafičkoj umjetnosti donose autohtone proizvodne i distribucijske procese, bez presedana u povijesti. Demokratičnost umnoživosti tradicionalnog grafičkog medija, jednom ograničena kapacitetom manualnog tiska, danas visokotehnološkim (digitalnim) sredstvima dostiže nivo apsolutne demokratičnosti i „elektronske utopije“. Ako je otisak kao multioriginal krajnji produkt grafike, onda je grafika danas, zahvaljujući novim medijima, više nego živa u vrijeme „jedinstvenih kopija“ – hiper multiplikacija i simulacija. Ovaj rad ima za cilj razmotriti nerazriješenu problemsku etapu intriga i konflikata o statusu i ulozi novih medija u grafičkoj umjetnosti.
This work deals with computational anatomy, an emerging discipline recognised in medical science as a derivative of conventional anatomy. It is also a completely new research area on the boundaries ...of several sciences and technologies, such as medical imaging, computer vision, and applied mathematics.
