Abstract

This work develops highly efficient algorithms for analyzing large images. Applications include object-based change detection and screening. The algorithms are 10-100 times as fast as existing software, sometimes even outperforming FGPA/GPU hardware, because they are designed to suit the computer architecture. This thesis describes the implementation details and the underlying algorithm engineering methodology, so that both may also be applied to other applications.

Abstract

This work presents a method to detect and classify varnish defects on wood surfaces. Since these defects are only partially visible under certain illumination directions, one image doesn't provide enough information for a recognition task. A classification requires inspecting the surface under different illumination directions, which results in image series. The information is distributed along this series and can be extracted by merging the knowledge about the defect shape and light direction.

Abstract

Photon-counting image sensors represent a possible paradigm shift in solid-state image sensors. In these devices, photons are individually sensed and counted. To count photons, the devices must have high quantum efficiency, deep sub-electron read noise and the ability to read-out in digital form at high speed. This all-invited content from the top image sensor researchers around the world, reviews the state of the art of photon-counting image sensors in a variety of configurations, including CMOS image sensors and devices using avalanche multiplication, and for visible photons as well as higher energy photons such as ultraviolet and x-rays. New methods of creating image information from photon-counting image sensors is also described. This new emerging technology will have applications in low-light scientific imaging for aerospace and defense, and in the life sciences. It may also have applications in cryptography, communications, security cameras, 3D imaging and photography.

Abstract

Mass-spring systems are considered the simplest and most intuitive of all deformable models. They are computationally efficient, and can handle large deformations with ease. But they suffer several intrinsic limitations. In this book a modified mass-spring system for physically based deformation modeling that addresses the limitations and solves them elegantly is presented. Several implementations in modeling breast mechanics, heart mechanics and for elastic images registration are presented.

Abstract

Image analysis is a fundamental task for extracting information from images acquired across a range of different devices. Since reliable quantitative results are requested, image analysis requires highly sophisticated numerical and analytical methods—particularly for applications in medicine, security, and remote sensing, where the results of the processing may consist of vitally important data. The contributions to this book provide a good overview of the most important demands and solutions concerning this research area. In particular, the reader will find image analysis applied for feature extraction, encryption and decryption of data, color segmentation, and in the support new technologies. In all the contributions, entropy plays a pivotal role.

Abstract

Since the beginning of reception, Büchner's epoch-making narrative Lenz was praised for its iconic quality, for the suggestive verbal mediacy of visual experience and the evocation of mental pictures. But so far research has paid no attention to the fact that this specific interrelation of language and image also strongly influenced the reception of the narrative in the fine arts. For the first time, this study analyses the complex relations between text and image in Lenz and its reception comprehensively, i.e. in consideration of the trias of literary communication: author, work and (artistic) reader. Firstly it is shown how the text-image-relations form the aesthetic fundament of the narrative as means of composition, but also as thematic, metareflexive element. Subsequently the different forms of imagery are analysed, which are generated in this way. The final part of the study presents illustrations based on Lenz and confronts them with the text. More than 700 pictures from 47 artists could be found, e.g. the expressive self-portraits of Walter Gramatté, Toyen's surrealistic compositions, the 'degenerative' etchings of Susanne Theumer or Thomas Kohl's landscape-representations.

Abstract

Symmetry has a central role in the study of vision. The concept of symmetry has an ancient origin in considerations of visual appearance; in modern times, abstracted and formalized into Group Theory, it has found spectacular applications, far beyond the visible; but its importance for vision persists in many ways including:• As a non-accidental feature of an image that cues affordances, 3D structure or the semantic categories of object present.• As a redundant aspect of an image which many be exploited for simplicity and compactness of encoding.• As a salient feature that draws attention, and evokes distinctive brain responses.• As a constraint on priors on the distribution of structures to be found in the natural world.• As an aesthetic principle.• As a design principle for vision systems.• The original idea for a Special Issue came from a symposium at the European Conference in Visual Perception, in 2015, on the topic of brain responses to visual symmetry, but we have now extended the scope. This Special Issue is devoted to provide a shared place for cutting edge studies on how and why symmetry is processed and exploited by biological and artificial visual systems.

Abstract

How to account for the peculiar attraction of certain photos? How to deal with the specific use of images in particular contexts? Monika Schwärzler presents a variety of photographic case studies exploring visual phenomena from the point of view of media analysis as well as from sociological, aesthetic, and psychoanalytic perspectives. The topics range from a new reading of Thomas Struth’s street photographs to CERN photos with their charged rhetoric, from the assault of photographic close-ups to speculations on an anonymous slide collection featuring a woman with an ever-present white handbag. The book is intended for an audience receptive to the analytical appeal of images, prepared to go beyond what can be taken at face value.

Abstract

This Special Issue "Advanced Nanoindentation in Materials" contains some of the latest developments in the field of small-scale contact mechanics for a wide range of materials and biological cells. The featured manuscript revealed a new ultra-high strain rate nanoindentation method that will enable new scientific understanding of time-dependent material properties. The book also presents unique material properties of super alloys and other structural materials characterized by indentation methods. In addition to engineering materials, deformation behaviors of live cancer cells on sharp pillar structures were discussed in this book with the hope to stimulate interest in the mechanical contact behaviors of biological cells.

Abstract

Selbstdarstellung, Image- und Beziehungsarbeit spielen in der Wissenschaft eine zentrale Rolle. Dieses Buch untersucht aus vornehmlich gesprächsanalytischer Perspektive, wie Images und Beziehungen der Akteure interaktiv konstituiert und ausgehandelt werden. Im Fokus stehen dabei Fachdiskussionen von Wissenschaftlern auf interdisziplinären Konferenzen. Grundlage ist ein von Soziologie und Psychologie befruchtetes linguistisches Methodeninventar. Die Autorin zeigt, wie Wissenschaftler in Diskussionen Images aufbauen, angreifen und verteidigen, wobei die Fachidentität der Akteure von zentraler Bedeutung ist. Sie erklärt ebenso, wie Wissenschaftler Kompetenz – auch bei vorhandenem Nichtwissen – signalisieren und Humor zur Beziehungsgestaltung nutzen.
