Download or read book Advances in Photometric 3D Reconstruction written by Jean-Denis Durou and published by Springer Nature. This book was released on 2020-09-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest advances in photometric 3D reconstruction. It provides the reader with an overview of the state of the art in the field, and of the latest research into both the theoretical foundations of photometric 3D reconstruction and its practical application in several fields (including security, medicine, cultural heritage and archiving, and engineering). These techniques play a crucial role within such emerging technologies as 3D printing, since they permit the direct conversion of an image into a solid object. The book covers both theoretical analysis and real-world applications, highlighting the importance of deepening interdisciplinary skills, and as such will be of interest to both academic researchers and practitioners from the computer vision and mathematical 3D modeling communities, as well as engineers involved in 3D printing. No prior background is required beyond a general knowledge of classical computer vision models, numerical methods for optimization, and partial differential equations.

Available in PDF, EPUB and Kindle. Book excerpt: Die Rekonstruktion von 3D-Gestaltinformationen ist eine fundamentale Aufgabenstellung im Bereich Computer-Vision. Unter den verschiedenen Techniken ist das sogenannte Photometrische Stereo Verfahren (PS) hervorzuheben, da es im Vergleich zu anderen Ansätzen ein höheres Potenzial für eine hoch genaue 3D-Rekonstruktion besitzt. Diese Arbeit befasst sich mit Verallgemeinerungen klassischer PS-Ansätze, die dieses Potenzial weiter ausschöpfen sollen. Die Entwicklungen können beispielsweise verwendet werden, um in Zukunft die 3D-Information in verschiedensten Bereichen für einen Anwender zu erschließen, wie etwa in der Medizin, der Film- und Videospieleindustrie, beim autonomen Fahren oder für Anwendungen in der virtuellen Realität. Die erste der Neuentwicklungen betrifft die systematische Verwendung von hellen Lichtreflexionen in der Berechnung der 3D-Rekonstruktion sowie die perspektivische Projektion. Hierdurch werden Beschränkungen üblicher Methoden, wie auf die Rekonstruktion diffus reflektierender Materialien und auf relativ weit entfernte Objekte, aufgehoben. Die Anwendbarkeit des entwickelten Ansatzes wird mittels der Rekonstruktion aus endoskopischen Bildern mit vielen hellen Lichtreflexionen untermauert. In einem weiteren Schritt wird gezeigt, wie man in Echtzeit eine 3D-Rekonstruktion auch von sehr feinen Details mittels eines verallgemeinerten Reflexionsmodells erreichen kann. Hierdurch werden hochaufgelöste Rekonstruktionen auch von Details erreicht, die für das menschliche Auge in Bildern unsichtbar sind. Hieraus ergeben sich viele potenzielle Anwendungsmöglichkeiten, etwa im Bereich der automatischen Detektion von Mikrodruck, die im Sicherheitsbereich Verwendung finden, oder in der industriellen Produktion für die Detektion sehr feiner Strukturen wie etwa gedruckter Schaltkreise. Als weiterer Beitrag der Arbeit wird ein Verfahren für das sogenannte nicht-kalibrierte PS entwickelt, bei dem neuronale Netzwerke verwendet werden, um die in diesem Fall fehlende Information der Beleuchtungsrichtung auszugleichen. Schließlich wird zum ersten Mal in der Literatur beschrieben, wie man basierend auf Metaheuristiken und tiefen neuronalen Netzen eine qualitativ hochwertige 3D-Rekonstruktion allein durch Bilder aus dem Internet oder natürliche Bilder ohne weiteres zusätzliches Wissen erlangt.zeige weniger.

Available in PDF, EPUB and Kindle. Book excerpt: The volume collects several contributions to the INDAM workshop Mathematical Methods for Objects Reconstruction: from 3D Vision to 3D Printing held in Rome, February, 2021. The goal of the workshop was to discuss new methods and conceptual structures for managing these challenging problems. The chapters reflect this goal and the authors are academic researchers and some experts from industry working in the areas of 3D modeling, computer vision, 3D printing and/or developing new mathematical methods for these problems. The contributions present methodologies and challenges raised by the emergence of large-scale 3D reconstruction applications and low-cost 3D printers. The volume collects complementary knowledges from different areas of mathematics, computer science and engineering on research topics related to 3D printing, which are, so far, widely unexplored. Young researchers and future scientific leaders in the field of 3D data acquisition, 3D scene reconstruction, and 3D printing software development will find an excellent introduction to these problems and to the mathematical techniques necessary to solve them.

Book excerpt: It is with great pleasure that we present the proceedings of the 6th Inter- tional, Symposium on Visual Computing (ISVC 2010), which was held in Las Vegas, Nevada. ISVC provides a common umbrella for the four main areas of visual computing including vision, graphics, visualization, and virtual reality. The goal is to provide a forum for researchers, scientists, engineers, and pr- titioners throughout the world to present their latest research ?ndings, ideas, developments, and applications in the broader area of visual computing. This year, the program consisted of 14 oral sessions, one poster session, 7 special tracks, and 6 keynote presentations. The response to the call for papers was very good; we received over 300 submissions for the main symposium from which we accepted 93 papers for oral presentation and 73 papers for poster p- sentation. Special track papers were solicited separately through the Organizing and Program Committees of each track. A total of 44 papers were accepted for oral presentation and 6 papers for poster presentation in the special tracks.

Download or read book Advanced Fingerprint Recognition From 3D Shape to Ridge Detail written by Feng Liu and published by Springer Nature. This book was released on 2020-05-22 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fingerprints are among the most widely used biometric modalities and have been successfully applied in various scenarios. For example, in forensics, fingerprints serve as important legal evidence; and in civilian applications, fingerprints are used for access and attendance control as well as other identity services. Thanks to advances in three-dimensional (3D) and high-resolution imaging technology, it is now feasible to capture 3D or high-resolution fingerprints to provide extra information and go beyond the traditional features such as global ridge patterns and local ridge singularities used in conventional fingerprint recognition tasks. This book presents the state of the art in the acquisition and analysis of 3D and high-resolution fingerprints. Based on the authors’ research, this book focuses on advanced fingerprint recognition using 3D fingerprint features (i.e., finger shape, level 0 features) or high-resolution fingerprint features (i.e., ridge detail, level 3 features). It is a valuable resource for researchers, professionals and graduate students working in the field of computer vision, pattern recognition, security/biometrics practice, as well as interdisciplinary researchers.

Download or read book 3D Computer Vision written by Christian Wöhler and published by Springer Science & Business Media. This book was released on 2012-07-23 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This indispensable text introduces the foundations of three-dimensional computer vision and describes recent contributions to the field. Fully revised and updated, this much-anticipated new edition reviews a range of triangulation-based methods, including linear and bundle adjustment based approaches to scene reconstruction and camera calibration, stereo vision, point cloud segmentation, and pose estimation of rigid, articulated, and flexible objects. Also covered are intensity-based techniques that evaluate the pixel grey values in the image to infer three-dimensional scene structure, and point spread function based approaches that exploit the effect of the optical system. The text shows how methods which integrate these concepts are able to increase reconstruction accuracy and robustness, describing applications in industrial quality inspection and metrology, human-robot interaction, and remote sensing.
