On using Directional Information for Parameter Space Decomposition in Ellipse Detection
In this paper we use the parametric polar representation to extend the application of edge directional information from circle to ellipse extraction. As a result we obtain a mapping which decomposes the parameter space required for ellipse extraction into two independent sub-spaces and one final histogram accumulator. The mapping includes the tangent of the angle of the first and second directional derivatives. These tangents are computed by considering edge direction at two border points. We show that the use of gradient information for parameter space decomposition avoids the intensive point labelling imposed by geometric constraints used by other approaches
Author interview: Q and A with Dr Kari Nixon on kept from all contagion: germ theory, disease and the dilemma of human contact in late nineteenth-century literature
In this author interview, we speak to Dr Kari Nixon about her new book Kept From All Contagion: Germ Theory, Disease and the Dilemma of Human Contact in Late Nineteenth-Century Literature. She discusses why the growing public awareness of germ theory between 1870 and 1900 makes for a fruitful period of study, how ‘Biopolitical Resistance Literature’ in the period responded to some of the anxieties that emerged, how these literary works might help us think about the challenges of the current COVID-19 pandemic and the value of the humanities for examining the implications of contagion and disease
On Using Gait in Forensic Biometrics
Given the continuing advances in gait biometrics, it appears prudent to investigate the translation of these techniques for forensic use. We address the question as to the confidence that might be given between any two such measurements. We use the locations of ankle, knee and hip to derive a measure of the match between walking subjects in image sequences. The Instantaneous Posture Match algorithm, using Harr templates, kinematics and anthropomorphic knowledge is used to determine their location. This is demonstrated using real CCTV recorded at Gatwick Airport, laboratory images from the multi-view CASIA-B dataset and an example of real scene of crime video. To access the measurement confidence we study the mean intra- and inter-match scores as a function of database size. These measures converge to constant and separate values, indicating that the match measure derived from individual comparisons is considerably smaller than the average match measure from a population

Invariant Characterisation of the Hough Transform for Pose Estimation of Arbitrary Shapes
In this paper we develop a new formulation and methodology for including invariance in a general form of the Hough transform. Essentially, the transformations that control a shape's appearance are extracted using invariance, for arbitrary shapes with a continuous description. We first develop a formal definition of the Hough transform mapping for arbitrary shapes and general transformations. We then include an invariant characterisation of shapes and develop and apply our new technique to extract shapes under similarity and affine transformations. Our formulation and implementation is based directly on parametric curves and so avoids the use of indexed look-up tables. This confers the attributes of a continuous shape description avoiding discretisation problems inherent in earlier formulations. To obtain an invariant characterisation, each point in the model is related to a collection of other points defining a geometric arrangement. This characterisation does not require the computation of properties for lines or other primitives that compose the model, but is based solely on the local geometry of the points on shapes. The transformation is obtained by solving for the parameters of the curve according to an arrangement of points defined for a point in the image and a corresponding arrangement of points for a point in the model with the same invariant properties. The location parameters can be gathered in a 2D accumulator space independent of the transformation and of a shape's complexity. Experimental results show that the new technique is capable of extracting arbitrary shapes under occlusion and when the image contains noise. As such this new formulation retains the known performance advantages of the Hough transform, whilst combining a continuous shape description with invariant mappings
Soft biometrics for surveillance: an overview
Biometrics is the science of automatically recognizing people based on physical or behavioral characteristics such as face, fingerprint, iris, hand, voice, gait and signature. More recently, the use of soft biometric traits has been proposed to improve the performance of traditional biometric systems and allow identification based on human descriptions. Soft biometric traits include characteristics such as height, weight, body geometry, scars, marks and tattoos (SMT), gender, etc. These traits offer several advantages over traditional biometric techniques. Soft biometric traits can be typically described using human understandable labels and measurements, allowing for retrieval and recognition solely based on verbal descriptions. Unlike many primary biometric traits, soft biometrics can be obtained at a distance without subject cooperation and from low quality video footage, making them ideal for use in surveillance applications. This chapter will introduce the current state-of-the-art in the emerging field of soft biometric

The Nixon Doctrine & The Navy
Most people understand that the Nixon Doctrine involves a lowering of the U.S. profile throughout the world and further, places some limitations on our willingness to intervene overseas. The author is not nearly so confident that there is widespread understanding of some of its other implications and believes that it would be a mistake to view the Nixon Doctrine as an arbitrary decision by a single administration. On the contrary, the Nixon Doctrine seems to have been dictated by the course of world events
Nixon a life
The rise, fall, and rebirth of Richard Nixon is perhaps the most fascinating story in American politics. Presidential chronicles and other outside sources have tried to capture it in full, but Nixon: A Life is the first to succeed. Nixon: A Life is the first entirely objective biography of Richard Nixon. Jonathan Aitken, who, in addition to serving in Parliament, serves as Her Majesty's Minister of State for Defense, conducted over sixty hours of interviews with Nixon and was granted unprecedented access to thousands of pages of Nixon's previously sealed private documents. The results of Aitken's interviews and research shed new light on a presidency that is just now beginning to be understood by serious students of history. Among the questions Aitken answers with fresh insight are:. Why didn't Nixon burn the Watergate tapes? How did he achieve his astonishing comebacks after being defeated by Kennedy in 1960 and resigning from the presidency in 1974? What were his relationships with political figures such as Dwight Eisenhower, John F. Kennedy, Henry Kissinger, and personal friends such as Bebe Rebozo and Robert Abplanalp? What caused him to overcome his doubts and pursue the Alger Hiss spy case in Congress? What are Nixon's innermost spiritual beliefs and intellectual influences? What drives him now? Previously published in Great Britain to rave reviews, Nixon: A Life is the first Nixon biography written by a non-American author. Aitken's refreshingly unencumbered positions on Watergate and Vietnam provide a unique perspective on Nixon's life and his presidency. Nixon: A Life breaks important new ground as a major work of political biography. It is a work that will inspire historians to recognize the outstanding diplomatic achievements of a man whose journey from tainted politician to respected foreign policy expert and elder statesman has been nothing short of remarkable
Healing Richard Nixon: A Doctor\u27s Memoir
Richard M. Nixon remains an enigma even thirty years after his resignation. Of the many portraits of this complex man, none have been more intimate or revealing than this memoir from his personal physician, friend, and confidante of more than forty years, John C. Lungren, M.D. Dr. Lungren, with his son and co-author John C. Lungren Jr., portrays Nixon as a paradoxical man—intense, compassionate, guarded, intelligent, resilient, deeply religious, enormously successful but ultimately tragic.
Lungren describes his battle to restore the president’s health after his resignation and reveals previously unknown details about Nixon’s two intensive hospitalizations, his near fatal vascular collapse, and his depression. Lungren experienced firsthand Nixon’s thoughts and feelings during the public scrutiny of federal prosecution for his role in the Watergate break-in. Accused of shielding his friend, Lungren himself came under fire; his private office was even burgled in an apparent attempt to copy Nixon’s private medical records.
Using previously unpublished sources, original correspondence, and private photographs, Healing Richard Nixon places Nixon in a new light. No future research or conclusions about Nixon—the man or the president—will be complete without consulting this fascinating memoir.
The late John C. Lungren M.D. became Richard Nixon\u27s personal physician in 1952.
John C Lungren Jr. is a former reporter for Knight-Ridder and author of Hesburgh of Notre Dame:Priest, Educator, Public Servant.
Lungren describes the real Nixon, as he struggled with and ultimately overcame near-fatal illness, depression, and political ridicule to become an ‘elder statesman’ constructively advancing international stability. —Choice
Rather than retelling the familiar facts, the authors provide a fresh perspective: that of Nixon’s personal physician, a post the senior Lungren held from 1952 until the early 1980s. —ForeWord
Out of all the books written about President Richard Nixon, the Lungrens have authored one of the few chronicles I find to be totally accurate. Brings the reader a personal view of Nixon which only would be available to a long-time personal friend and a doctor who stayed within his code of ethics even under the pressure of Watergate. —Herbert G. Klein, Former Nixon Administration White House Director of Communications
Essential reading for anyone wishing to understand all the dimensions of a great architect of peace. —John H. Taylor, Director, Richard Nixon Library & Birthplace
Valuable for its conversation about Nixon\u27s medical ordeals. Dr. Lungren admires Nixon but recognized some of his faults. —Library Journalhttps://uknowledge.uky.edu/upk_political_history/1023/thumbnail.jp
