Available in PDF, EPUB and Kindle. Book excerpt: As new displays and cameras offer enhanced color capabilities, there is a need to extend the precision of digital content. High Dynamic Range (HDR) imaging encodes images and video with higher than normal 8 bit-per-color-channel precision, enabling representation of the complete color gamut and the full visible range of luminance.However, to realize transition from the traditional toHDRimaging, it is necessary to develop imaging algorithms that work with the high-precision data. Tomake such algorithms effective and feasible in practice, it is necessary to take advantage of the limitations of the human visual system by aligning the data shortcomings to those of the human eye, thus limiting storage and processing precision. Therefore, human visual perception is the key component of the solutions we discuss in this book. This book presents a complete pipeline forHDR image and video processing fromacquisition, through compression and quality evaluation, to display. At the HDR image and video acquisition stage specialized HDR sensors or multi-exposure techniques suitable for traditional cameras are discussed. Then, we present a practical solution for pixel values calibration in terms of photometric or radiometric quantities, which are required in some technically oriented applications. Also, we cover the problem of efficient image and video compression and encoding either for storage or transmission purposes, including the aspect of backward compatibility with existing formats. Finally, we review existing HDR display technologies and the associated problems of image contrast and brightness adjustment. For this purpose tone mapping is employed to accommodate HDR content to LDR devices. Conversely, the so-called inverse tone mapping is required to upgrade LDR content for displaying on HDR devices. We overview HDR-enabled image and video quality metrics, which are needed to verify algorithms at all stages of the pipeline. Additionally, we cover successful examples of the HDR technology applications, in particular, in computer graphics and computer vision. The goal of this book is to present all discussed components of the HDR pipeline with the main focus on video. For some pipeline stages HDR video solutions are either not well established or do not exist at all, in which case we describe techniques for single HDR images. In such cases we attempt to select the techniques, which can be extended into temporal domain. Whenever needed, relevant background information on human perception is given, which enables better understanding of the design choices behind the discussed algorithms and HDR equipment.

Available in PDF, EPUB and Kindle. Book excerpt: Dr AIvy Ray Smith Executive Vice President, Pixar The pOlyglot language of computer animation has arisen piecemeal as a collection of terms borrowed from geometry, film, video, painting, conventional animation, computer graphiCS, computer science, and publishing - in fact, from every older art or science which has anything to do with pictures and picture making. Robi Roncarelli, who has already demonstrated his foresight by formally identifying a nascent industry and addressing his Computer Animation Newsletter to it, here again makes a useful contribution to it by codifying its jargon. My pleasure in reading his dictionary comes additionally from the many historical notes sprinkled throughout and from surprise entries such as the one referring to Zimbabwe. Just as Samuel Johnson's dictionary of the English language was a major force in stabilizing the spelling of English, perhaps this one will serve a similar purpose for computer animation. Two of my pets are "color" for "colour" and "modeling" "modelling", under the rule that the shorter accepted spelling is always preferable. [Robi, are you reading this?] [Yes, AIvy!] Now I commend this book to you, whether you be a newcomer or an oldtimer.

KUNII Preface to the Second Edition Computer graphics is growing very rapidly; only computer animation grows faster. The first edition of the book Computer Animation: Theory and Practice was released in 1985. Four years later, computer animation has exploded. Conferences on computer animation have appeared and the topic is recognized in well-known journals as a leading theme. Computer-generated film festivals now exist in each country and several thousands of films are produced each year. From a commercial point of view, the computer animation market has grown considerably. TV logos are computer-made and more and more simulations use the technique of computer animation. What is the most fascinating is certainly the development of computer animation from a research point-of-view.

Book excerpt: A behind-the-scenes history of computer graphics, featuring a cast of math nerds, avant-garde artists, cold warriors, hippies, video game players, and studio executives. Computer graphics (or CG) has changed the way we experience the art of moving images. Computer graphics is the difference between Steamboat Willie and Buzz Lightyear, between ping pong and PONG. It began in 1963 when an MIT graduate student named Ivan Sutherland created Sketchpad, the first true computer animation program. Sutherland noted: “Since motion can be put into Sketchpad drawings, it might be exciting to try making cartoons.” This book, the first full-length history of CG, shows us how Sutherland's seemingly offhand idea grew into a multibillion dollar industry. In Moving Innovation, Tom Sito—himself an animator and industry insider for more than thirty years—describes the evolution of CG. His story features a memorable cast of characters—math nerds, avant-garde artists, cold warriors, hippies, video game enthusiasts, and studio executives: disparate types united by a common vision. Sito shows us how fifty years of work by this motley crew made movies like Toy Story and Avatar possible.

Available in PDF, EPUB and Kindle. Book excerpt: During the past decade, high-performance computer graphics have found application in an exciting and expanding range of new domains. Among the most dramatic developments has been the incorporation of real-time interactive manipulation and display for human figures. Though actively pursued by several research groups, the problem of providing a synthetic or surrogate human for engineers and designers already familiar with computer-aided design techniques was most comprehensively solved by Norman Badler's computer graphics laboratory at the University of Pennsylvania. The breadth of that effort as well as the details of its methodology and software environment are presented in this volume. The book is intended for human factors engineers interested in understanding how a computer-graphics surrogate human can augment their analyses of designed environments. It will also inform design engineers of the state of the art in human figure modeling, and hence of the human-centered design central to the emergent concept of concurrent engineering. In fulfilling these goals, the book additionally documents for the entire computer graphics community a major research effort in the interactive control of articulated human figures.

Download or read book Animation and Performance Capture Using Digitized Models written by Edilson de Aguiar and published by Springer Science & Business Media. This book was released on 2009-12-08 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The realistic generation of virtual doubles of real-world actors has been the focus of computer graphics research for many years. However, some problems still remain unsolved: it is still time-consuming to generate character animations using the traditional skeleton-based pipeline, passive performance capture of human actors wearing arbitrary everyday apparel is still challenging, and until now, there is only a limited amount of techniques for processing and modifying mesh animations, in contrast to the huge amount of skeleton-based techniques. In this thesis, we propose algorithmic solutions to each of these problems. First, two efficient mesh-based alternatives to simplify the overall character animation process are proposed. Although abandoning the concept of a kinematic skeleton, both techniques can be directly integrated in the traditional pipeline, generating animations with realistic body deformations. Thereafter, three passive performance capture methods are presented which employ a deformable model as underlying scene representation. The techniques are able to jointly reconstruct spatio-temporally coherent time-varying geometry, motion, and textural surface appearance of subjects wearing loose and everyday apparel. Moreover, the acquired high-quality reconstructions enable us to render realistic 3D Videos. At the end, two novel algorithms for processing mesh animations are described. The first one enables the fully-automatic conversion of a mesh animation into a skeletonbased animation and the second one automatically converts a mesh animation into an animation collage, a new artistic style for rendering animations. The methods described in the thesis can be regarded as solutions to specific problems or important building blocks for a larger application. As a whole, they form a powerful system to accurately capture, manipulate and realistically render realworld human performances, exceeding the capabilities of many related capture techniques. By this means, we are able to correctly capture the motion, the timevarying details and the texture information of a real human performing, and transform it into a fully-rigged character animation, that can be directly used by an animator, or use it to realistically display the actor from arbitrary viewpoints.
