Warping & Morphing of Graphical Objects


Book Description

Warping and morphing permeate the realm of computer graphics. This classic book defines the field: it presents a unifying view of warping and morphing, combining a conceptual framework with a consolidated view of the state of the art. Coverage includes deformations of various graphical objects such as plane curves, images, surfaces, and volumes. The authors developed a full-featured warping and morphing system, Morphos, where several types of graphical objects and computation techniques coexist. Morphos is included on the companion CD-ROM. This book and CD-ROM offer the most comprehensive professional reference available on warping and morphing techniques. Together they are the complete source for both researchers whose main interests are in the mathematical and conceptual foundations and computer graphics professionals who need to incorporate more warping and morphing techniques into their applications. Features: *The latest warping and morphing techniques and examples *An entire chapter on image-based rendering techniques and how they relate to warping and morphing *Companion CD-ROM containing source code and documentation for the Morphos system *Links to www.visgraf.impa.br/morph/, which provides an online bibliography and pointers to other regularly updated morphing websites

Intelligent Techniques in Signal Processing for Multimedia Security


Book Description

This book proposes new algorithms to ensure secured communications and prevent unauthorized data exchange in secured multimedia systems. Focusing on numerous applications’ algorithms and scenarios, it offers an in-depth analysis of data hiding technologies including watermarking, cryptography, encryption, copy control, and authentication. The authors present a framework for visual data hiding technologies that resolves emerging problems of modern multimedia applications in several contexts including the medical, healthcare, education, and wireless communication networking domains. Further, it introduces several intelligent security techniques with real-time implementation. As part of its comprehensive coverage, the book discusses contemporary multimedia authentication and fingerprinting techniques, while also proposing personal authentication/recognition systems based on hand images, surveillance system security using gait recognition, face recognition under restricted constraints such as dry/wet face conditions, and three-dimensional face identification using the approach developed here. This book equips perception technology professionals with the latest technologies, techniques, and strategies for multimedia security systems, offering a valuable resource for engineers and researchers working to develop security systems.




Advances in Visual Computing


Book Description

This book constitutes the refereed proceedings of the First International Symposium on Visual Computing, ISVC 2005, held in Lake Tahoe, NV, USA in December 2005. The 33 revised full papers and 26 poster papers presented together with 5 keynote presentations and 1 invited talk were carefully reviewed and selected from 110 submissions. The papers are rounded off by 32 presentations held at seven special tracks. The papers cover the four main areas of visual computing: vision, graphics, visualization, and virtual reality. Topics addressed are computer graphics, medical imaging, computer vision methods for ambient intelligence, virtual reality and medicine, pattern analysis and recognition applications in biometrics, visualization, mediated reality, visual surveillance in challenging environments, low level vision, encoding and compression, segmentation, recognition and reconstruction, motion, text extraction and retrieval, intelligent vehicles and autonomous navigation, and visualization techniques in geophysical science.




Image Processing for Computer Graphics


Book Description

The focus of this book is on providing a thorough treatment of image processing with an emphasis on those aspects most used in computer graphics. Throughout, the authors concentrate on describing and analysing the underlying concepts rather than on presenting algorithms or pseudocode. As befits a modern introduction to this topic, a healthy balance is struck between discussing the underlying mathematics of the subject and the main topics covered: signal processing, data discretization, the theory of colour and different colour systems, operations in images, dithering and half-toning, warping and morphing, and image processing.




Information Retrieval for Music and Motion


Book Description

Content-based multimedia retrieval is a challenging research field with many unsolved problems. This monograph details concepts and algorithms for robust and efficient information retrieval of two different types of multimedia data: waveform-based music data and human motion data. It first examines several approaches in music information retrieval, in particular general strategies as well as efficient algorithms. The book then introduces a general and unified framework for motion analysis, retrieval, and classification, highlighting the design of suitable features, the notion of similarity used to compare data streams, and data organization.




Graph Drawing


Book Description

This book constitutes the thoroughly refereed post-proceedings of the 13th International Symposium on Graph Drawing, GD 2005, held in Limerick, Ireland in September 2005. The 38 revised full papers and 3 revised short papers presented together with 3 software demos, 8 posters and a report on the graph drawing contest were carefully selected during two rounds of reviewing and improvement from 101 submissions. All current aspects in graph drawing are addressed ranging from foundational and methodological issues to applications for various classes of graphs in a variety of fields. Also included is a report on the Workshop on Network Analysis and Visualisation held in conjunction with the conference.







Rendering Techniques 2001


Book Description

This book contains the proceedings of the lih Eurographics Workshop on Rendering, th which took place from the 25 to the 27th of June, 2001, in London, United Kingdom. Over the past 11 years, the workshop has become the premier forum dedicated to research in rendering. Much of the work in rendering now appearing in other conferences and journals builds on ideas originally presented at the workshop. This year we received a total of 74 submissions. Each paper was carefully reviewed by two of the 28 international programme committee members, as well as external reviewers, selected by the co-chairs from a pool of 125 individuals. In this review process, all submissions and reviews were handled electronically, with the exception of videos submitted with a few of the papers. The overall quality of the submissions was exceptionally high. Space and time constraints forced the committee to make some difficult decisions. In the end, 29 by papers were accepted, and they appear here. Almost all papers are accompanied color images, which appear at the end of the book. The papers treat the following varied topics: methods for local and global illumination, techniques for acquisition and modeling from images, image-based rendering, new image representations, hardware assisted methods, shadow algorithms, visibility, perception, texturing, and filtering. Each year, in addition to the reviewed contributions, the workshop includes invited presentations from internationally recognized experts.
