This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we introduce a novel algorithm for reconstructing the 3D shape and texture model of human faces from two stereo images which are captured from calibrated cameras. Our approach works in a sparse to dense manner: we first build a coarse shape estimation based on 3D keypoints, and then use a linear morphable model to efficiently match the detailed shape and texture. The features used for the fitting processes are selected with the guidance of the quantitative evaluation of a state-of-the-art reconstruction algorithm. In our new direct evaluation method, the reconstructed 3D faces are first aligned to the ground truth and then the shape difference between the two 3D faces is described by signal-to-noise ratio and error maps illustrating the reconstruction errors on corresponding vertices. This local error information will be used to resample the reference frame whose vertices' coordinates stack up to be the feature vectors for face fitting. Compared with the previous works, our algorithm can reconstruct the 3D face shape at a speed comparable with that of the fastest algorithm available, but gives a higher accuracy. It can also recover the more complete and realistic looking texture. Our results show that the new algorithm possesses significant characteristics of a 3D face model reconstruction system, and is especially useful for face recognition and animation applications in practice.

Available in PDF, EPUB and Kindle. Book excerpt: 3D face reconstruction and tracking has become an important research topic during the past few decades in both computer graphics and computer vision. Researchers are seeking for a method to model the human face using a low cost device with high quality. Currently, face models can be captured by expensive active sensor-like laser scanning; however, this sensor technology is not affordable for everyone and experiments must be conducted under certain conditions. In our thesis, we present an automatic 3D face reconstruction and pose estimation framework using a consumer depth camera. Our method does not require any prior face model database. We acquire location of human face part using regular face detector, and in order to generate a high quality face model, we integrate and register information from multiple frames together, which allows detection of noise. In addition, by detecting 2D landmark information provided by the RGB image, we are able to find correspondence in the 3D model. Results are demonstrated by visual inspection. Future application for our research may involve game design and face avatar generation.

This book was released on 2007-06-01 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports recent advances in the use of pattern recognition techniques for computer and robot vision. The sciences of pattern recognition and computational vision have been inextricably intertwined since their early days, some four decades ago with the emergence of fast digital computing. All computer vision techniques could be regarded as a form of pattern recognition, in the broadest sense of the term. Conversely, if one looks through the contents of a typical international pattern recognition conference proceedings, it appears that the large majority (perhaps 70-80%) of all pattern recognition papers are concerned with the analysis of images. In particular, these sciences overlap in areas of low level vision such as segmentation, edge detection and other kinds of feature extraction and region identification, which are the focus of this book.

Download or read book Image and Geometry Processing for 3 D Cinematography written by Rémi Ronfard and published by Springer Science & Business Media. This book was released on 2010-06-29 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: papers, illustrated with examples. They include wavelet bases, implicit functions de ned on a space grid, etc. It appears that a common pattern is the recovery of a controllable model of the scene, such that the resulting images can be edited (interaction). Changing the viewpoint is only one (important) aspect, but changing the lighting and action is equally important [2]. Recording and representing three-dimensional scenes is an emerging technology made possible by the convergence of optics, geometry and computer science, with many applications in the movie industry, and more generally in entertainment. Note that the invention of cinema (camera and projector) was also primarily a scienti c invention that evolved into an art form. We suspect the same thing will probably happen with 3-D movies. 3 Book Contents The book is composed of 12 chapters, which elaborate on the content of talks given at the BANFF workshop. The chapters are organized into three sections. The rst section presents an overview of the inter-relations between the art of cinemat- raphy and the science of image and geometry processing; the second section is devoted to recent developments in geometry; and the third section is devoted to recent developmentsin image processing. 3.1 3-D Cinematography and Applications The rst section of the book presents an overview of the inter-relations between the art of cinematography and the science of image and geometry processing.

Book excerpt: Zusammenfassung: This book offers a comprehensive and unbiased introduction to 3D Computer Vision, ranging from its foundations and essential principles to advanced methodologies and technologies. Divided into 11 chapters, it covers the main workflow of 3D computer vision as follows: camera imaging and calibration models; various modes and means of 3D image acquisition; binocular, trinocular and multi-ocular stereo vision matching techniques; monocular single-image and multi-image scene restoration methods; point cloud data processing and modeling; simultaneous location and mapping; generalized image and scene matching; and understanding spatial-temporal behavior. Each topic is addressed in a uniform manner: the dedicated chapter first covers the essential concepts and basic principles before presenting a selection of typical, specific methods and practical techniques. In turn, it introduces readers to the most important recent developments, especially in the last three years. This approach allows them to quickly familiarize themselves with the subject, implement the techniques discussed, and design or improve their own methods for specific applications. The book can be used as a textbook for graduate courses in computer science, computer engineering, electrical engineering, data science, and related subjects. It also offers a valuable reference guide for researchers and practitioners alike

Available in PDF, EPUB and Kindle. Book excerpt: As the speed, capabilities, and economic advantages of modern digital devices c- tinue to grow, the need for ef?cient information processing, especially in computer - sion and graphics, dramatically increases. Growth in these ?elds stimulated by eme- ing applications has been both in concepts and techniques. New ideas, concepts and techniques are developed, presented, discussed and evaluated, subsequently expanded or abandoned. Such processes take place in different forms in various ?elds of the c- puter science and technology. The objectives of the ICCVG are: presentation of current research topics and d- cussions leading to the integration of the community engaged in machine vision and computer graphics, carrying out and supporting research in the ?eld and ?nally pro- tion of new applications. The ICCVG is a continuation of the former International Conference on Computer Graphics and Image Processing called GKPO, held in Poland every second year in May since 1990, organized by the Institute of Computer Science of the Polish Academy of Sciences, Warsaw and chaired by the Editor of the International Journal of Machine Graphics and Vision, Prof. Wojciech S. Mokrzycki.
