Visual Tracking in Conventional Minimally Invasive Surgery

by Shahram Payandeh

Visual Tracking in Conventional Minimally Invasive Surgery introduces the various tools and methodologies that can be used to enhance a conventional surgical setup with some degree of automation. The main focus of this book is on methods for tracking surgical tools and how they can be used to assist the surgeon during the surgical operation. Various notions associated with surgeon–computer interfaces and image-guided navigation are explored, with a range of experimental results. The book starts with some basic motivations for minimally invasive surgery and states the various distinctions between robotic and non-robotic (conventional) versions of this procedure. Common components of this type of operation are presented with a review of the literature addressing the automation aspects of such a setup. Examples of tracking results are shown for both motion and gesture recognition of surgical tools, which can be used as part of the surgeon–computer interface. In the case of marker-less tracking, where no special visual markers can be added to the surgical tools, the tracking results are divided into two types of methodology, depending on the nature and the estimate of the visual noise. Details of the tracking methods are presented using standard Kalman filters and particle filters. The last part of the book provides approaches for tracking a region on the surgical scene defined by the surgeon. Examples of how these tracking approaches can be used as part of image-guided navigation are demonstrated. This book is designed for control engineers interested in visual tracking, computer vision researchers and system designers involved with surgical automation, as well as surgeons, biomedical engineers, and robotic researchers.

Visual and Non-Visual Effects of Light: Working Environment and Well-Being (Occupational Safety, Health, and Ergonomics)

by Agnieszka Wolska Dariusz Sawicki Malgorzata Tafil-Klawe

The introduction of artificial lighting extends the time of wakefulness after dark and enables work at night, thus disturbing the human circadian rhythm. The understanding of the physiological mechanisms of visual and non-visual systems may be important for the development and use of proper light infrastructure and light interventions for different workplace settings, especially for shift work conditions. Visual and Non-Visual Effects of Light: Working Environment and Well-Being presents the impact of lighting in the working environment on human health, well-being and visual performance. The physiological explanation of the visual and non-visual effects of light on humans which discusses the biological bases of image and non-image forming vision at the cellular level may be of particular interest to any professional in the field of medicine, physiology, and biology. It is one of the intentions of this book to put forward some recommendations and examples of lighting design which take into account both the visual and non-visual effects of light on humans. These may be of particular interest to any professional in the field of lighting, occupational safety and health, and interior design. "What effects on health can a light ‘overdose’ or light deficiency have? What is bad light? The authors of the monograph provide answers to these questions. Just as for a physicist, the dual nature of light comprises an electromagnetic wave and a photon, the duality of light for a physician comprises visual and non-visual effects." --------------------------------------------------------Prof Jacek Przybylski, Medical University of Warsaw "This is a unique publication in the field of lighting technology. The authors have skillfully combined both the technical and biomedical aspects involved, which is unprecedented in the literature available. As a result, an important study has been created for many professional groups, with a significant impact on the assessment of risks associated with LED sources." --------------------------------------------Prof Andrzej Zając, Military University of Technology, Warsaw

Visualization and Interpretation: Humanistic Approaches to Display

by Johanna Drucker

An analysis of visual epistemology in the digital humanities, reorienting the creation of digital tools within humanities contexts.In the several decades since humanists have taken up computational tools, they have borrowed many techniques from other fields, including visualization methods to create charts, graphs, diagrams, maps, and other graphic displays of information. But are these visualizations actually adequate for the interpretative approach that distinguishes much of the work in the humanities? Information visualization, as practiced today, lacks the interpretivist frameworks required for humanities-oriented methodologies. In this book, Johanna Drucker continues her interrogation of visual epistemology in the digital humanities, reorienting the creation of digital tools within humanities contexts.

Visualization for Artificial Intelligence (Synthesis Lectures on Visualization)

by Jun Yuan Shixia Liu Weikai Yang Junpeng Wang

This book explores how visualization provides an effective way of improving not only the interpretability but also the generalization capabilities of machine learning models. It shows how visualization can bridge the gap between complex models or algorithms and human understanding while also facilitating data curation and model refinement. Therefore, visualization for artificial intelligence (VIS4AI) has become an emerging area that combines interactive visualization with machine learning techniques to maximize their values. VIS4AI techniques focus on every phase of the machine learning life cycle, from data preprocessing to model development and deployment. These techniques are closely aligned with the well-established data and model pipelines in machine learning. In the data pipeline, they contribute to improving data quality and feature quality, including training data cleaning and feature engineering. In the model pipeline, they support (1) model development by focusing on model understanding, diagnosis, and steering; and (2) model deployment by enabling decision explanation, model performance monitoring, and model maintenance. This book provides a framework of VIS4AI and introduces the associated techniques in the two pipelines. It emphasizes the importance of interactive visualization in AI and presents various visualization techniques for different purposes. It also discusses the challenges and opportunities of VIS4AI and proposes several promising research topics for future work, such as improving training data using complementary modalities, online training diagnosis, fitting the dynamic nature of AI systems, and interactively pre-training and adapting foundation models. Overall, this book aims to serve as a resource for researchers and practitioners interested in both visualization and artificial intelligence.

Vital Media: Making, Design, and Expression for Humans and Other Materials

by Michael Nitsche

A proposal for a new media design to balance the contributions of humans and materials in the world they share.How can media design support a balance between our needs for self-expression and the material needs of the world we are part of? What criteria define a sustainable media ecology? In Vital Media, Michael Nitsche argues that the current human-centric view is not sustainable and that media are best viewed as dynamic networks where cognitive and noncognitive participants co-create. What we need, according to Nitsche, is a media design that balances the needs of all partners involved: vital media. Tracing this ideal through two domains of expression and making, performance and craft, Nitsche calls on us to embrace material co-existence and to design for self-expression as well as material evolution. We must recognize that the living body and its dependencies on the world around it are at the heart of what media are about. Vital media exist to not only help individuals fulfill their potential through expression but to also realize the agencies of materials in the equally active surrounding world. Throughout the book, Nitsche interweaves theory with close readings of actual artifacts that encompass predigital, nondigital, and hybrid examples. Nitsche&’s approach counters the current tendency to pit the virtual media world against the reality in which we live.

Vitamin B12: Advances and Insights

by Rima Obeid

Cobalamin (vitamin B12) was discovered in the first half of the 20th century. Vast amount of information on the role of the vitamins in human health and disease became available. Cobalamin science was, however, based on theoretical concepts that have been accepted without further proof of facts and hypotheses. Recently, the breath-taking pace of development in research technologies has changed our understanding for the role of nutrients and the complex interaction between diet, environment and diseases. Conditions like aging, diet and drugs increase the risk of developing cobalamin deficiency, probably because of diminished ability to liberate, absorb or distribute the food-derived vitamin. From a basic science point of view, understanding of the transport and function of the vitamin, may pave the road for using this system for drug delivery. This book represents up-to-date literature on the discoveries and developments in the field of cobalamin. It includes multifaceted aspects of the vitamin in health and disease conditions. The book has been written by leading scientists who have significant contributions in this field and represents therefore, a timely unique encyclopaedia on cobalamin.

Vitamin D im Überblick: Wissenschaftlich fundierte Grundlagen und aktuelle Forschungsergebnisse (essentials)

by Armin Zittermann

Vitamin D kann in der Haut durch die UV-B-Strahlung der Sonne gebildet sowie über bestimmte Lebensmittel und Supplemente zugeführt werden. Die aktive Vitamin-D-Form ist ein Steroidhormon mit Wirkungen in einer Vielzahl von Geweben. Ein Vitamin-D-Mangel ist in Deutschland weit verbreitet. Es gibt eine Reihe von Risikogruppen, vor allem aufgrund unzureichender kutaner Synthese. Neben den klassischen Vitamin-D-Mangelerkrankungen Rachitis und Osteomalazie ist ein Vitamin- D-Mangel vermutlich auch ein Risikofaktor für verschiedene weit verbreitete chronische Erkrankungen sowie für eine verkürzte Lebenserwartung. Zur Verbesserung der Vitamin-D-Versorgung der Bevölkerung sind umfangreichere Anreicherungsmaßnahmen von Lebensmitteln sowie eine stärkere Verwendung von Supplementen zu fordern.
