The Pincushion Effect


Book Description

American land surveying has a dilemma; it's called the "pincushion corner." This is a name used to describe the phenomena of multiple boundary monuments being set by land surveyors when only one boundary corner exists under the law. The pincushion has not gone unnoticed by the legal profession and the general public. It is now common knowledge that no two surveyors can agree on the location of any given property corner. The pincushion is physical proof of that notion. Not only is the pincushion becoming a public relations disaster for the profession, it is causing those who might otherwise consider commissioning a survey to decide otherwise. And herein lies the dilemma; no one wants to hire the surveyor because of the way surveying is practiced, the pincushion being emblematic of that practice. This book explores the effect of the pincushion, how the phenomena started, why it exists, and remedies to end the practices that allow the pincushion corner to not only exist, but to flourish.




Secrets of the Sideshows


Book Description

"Joe Nickell - once a carnival pitchman, then a magician, private detective, and investigative writer - has pursued sideshow secrets for years and has worked the famous carnival midway at the Canadian National Exhibition. For this book, he interviewed showmen and performers, collected carnival memorabilia, researched published accounts of sideshows and their lore, and even performed some classic sideshow feats, such as eating fire and lying on a bed of nails as a cinderblock was broken on his chest. The result of these varied efforts, Secrets of the Sideshows tells the captivating story of the magic, tricks - real or illusory - and performers of the world's midway shows."--BOOK JACKET.

The Great Zapruder Film Hoax


Book Description

This is the first book to expose a crucial aspect of the cover-up of the JFK assassination conspiracy: the doctoring of the Zapruder film, allegedly a 27-second home movie shot by Abraham Zapruder in Dealey Plaza. The evidence for alteration of the Zapruder movie takes many forms, including inconsistencies with eyewitness testimony, discrepancies with other films and photographs, impossible movements within the time-frame of the movie, contradictions between the movie and the physical layout of Dealey Plaza, and the multiple versions of the movie itself. This book brings together all the leading authorities within the assassination research community, including David Healy, authority on technical processes of film production; Jack White, who for forty years has made a special study of the JFK assassination movies and photographs; John Costella, Ph.D., a physicist and engineer with a background in optics, the properties of light, and moving objects; and David W. Mantick, Ph.D., the foremost expert on the medical evidence in the JFK assassination.




Photography in Clinical Medicine


Book Description

This book explains how medical photography is part of the workflow in many specialties: it is needed for registries, to preserve information, for follow up, second opinion and teaching, among others. The book gathers information on this field, providing valuable practical tips for those that have never used photography for medical uses as well as those who use it regularly. Covering specialities ranging from dermatology, plastic surgery, dentistry, ophthalmology and endoscopy to forensic medicine, specimen photography and veterinary medicine, it highlights standardization for each procedure and relevance to ethical, patients’ perception of medical photography, cybersecurity and legal aspects. The book also presents practical sections explaining how to organize a photographic file, coding, reimbursement, compliance, use of social media and preservation as well as in depth concepts on sharp focus on blurred vision. This volume will appeal to all clinicians and practitioners interested in acquiring a high level of technical skill in medical photography.




Epipolar Geometry


Book Description

What is Epipolar Geometry Epipolar geometry is the geometry of stereo vision. When two cameras view a 3D scene from two distinct positions, there are a number of geometric relations between the 3D points and their projections onto the 2D images that lead to constraints between the image points. These relations are derived based on the assumption that the cameras can be approximated by the pinhole camera model. How you will benefit (I) Insights, and validations about the following topics: Chapter 1: Epipolar geometry Chapter 2: Optical aberration Chapter 3: Focal length Chapter 4: Camera lens Chapter 5: 3D projection Chapter 6: Vanishing point Chapter 7: Distortion (optics) Chapter 8: Parallel projection Chapter 9: Collinearity Chapter 10: Fundamental matrix (computer vision) (II) Answering the public top questions about epipolar geometry. (III) Real world examples for the usage of epipolar geometry in many fields. Who this book is for Professionals, undergraduate and graduate students, enthusiasts, hobbyists, and those who want to go beyond basic knowledge or information for any kind of Epipolar Geometry.
