Available in PDF, EPUB and Kindle. Book excerpt: Current vision systems are designed to perform in normal weather condition. However, no one can escape from severe weather conditions. Bad weather reduces scene contrast and visibility, which results in degradation in the performance of various computer vision algorithms such as object tracking, segmentation and recognition. Thus, current vision systems must include some mechanisms that enable them to perform up to the mark in bad weather conditions such as rain and fog. Rain causes the spatial and temporal intensity variations in images or video frames. These intensity changes are due to the random distribution and high velocities of the raindrops. Fog causes low contrast and whiteness in the image and leads to a shift in the color. This book has studied rain and fog from the perspective of vision. The book has two main goals: 1) removal of rain from videos captured by a moving and static camera, 2) removal of the fog from images and videos captured by a moving single uncalibrated camera system. The book begins with a literature survey. Pros and cons of the selected prior art algorithms are described, and a general framework for the development of an efficient rain removal algorithm is explored. Temporal and spatiotemporal properties of rain pixels are analyzed and using these properties, two rain removal algorithms for the videos captured by a static camera are developed. For the removal of rain, temporal and spatiotemporal algorithms require fewer numbers of consecutive frames which reduces buffer size and delay. These algorithms do not assume the shape, size and velocity of raindrops which make it robust to different rain conditions (i.e., heavy rain, light rain and moderate rain). In a practical situation, there is no ground truth available for rain video. Thus, no reference quality metric is very useful in measuring the efficacy of the rain removal algorithms. Temporal variance and spatiotemporal variance are presented in this book as no reference quality metrics. An efficient rain removal algorithm using meteorological properties of rain is developed. The relation among the orientation of the raindrops, wind velocity and terminal velocity is established. This relation is used in the estimation of shape-based features of the raindrop. Meteorological property-based features helped to discriminate the rain and non-rain pixels. Most of the prior art algorithms are designed for the videos captured by a static camera. The use of global motion compensation with all rain removal algorithms designed for videos captured by static camera results in better accuracy for videos captured by moving camera. Qualitative and quantitative results confirm that probabilistic temporal, spatiotemporal and meteorological algorithms outperformed other prior art algorithms in terms of the perceptual quality, buffer size, execution delay and system cost. The work presented in this book can find wide application in entertainment industries, transportation, tracking and consumer electronics.

Available in PDF, EPUB and Kindle. Book excerpt: Every year lives and properties are lost in road accidents. About one-fourth of these accidents are due to low vision in foggy weather. At present, there is no algorithm that is specifically designed for the removal of fog from videos. Application of a single-image fog removal algorithm over each video frame is a time-consuming and costly affair. It is demonstrated that with the intelligent use of temporal redundancy, fog removal algorithms designed for a single image can be extended to the real-time video application. Results confirm that the presented framework used for the extension of the fog removal algorithms for images to videos can reduce the complexity to a great extent with no loss of perceptual quality. This paves the way for the real-life application of the video fog removal algorithm. In order to remove fog, an efficient fog removal algorithm using anisotropic diffusion is developed. The presented fog removal algorithm uses new dark channel assumption and anisotropic diffusion for the initialization and refinement of the airlight map, respectively. Use of anisotropic diffusion helps to estimate the better airlight map estimation. The said fog removal algorithm requires a single image captured by uncalibrated camera system. The anisotropic diffusion-based fog removal algorithm can be applied in both RGB and HSI color space. This book shows that the use of HSI color space reduces the complexity further. The said fog removal algorithm requires pre- and post-processing steps for the better restoration of the foggy image. These pre- and post-processing steps have either data-driven or constant parameters that avoid the user intervention. Presented fog removal algorithm is independent of the intensity of the fog, thus even in the case of the heavy fog presented algorithm performs well. Qualitative and quantitative results confirm that the presented fog removal algorithm outperformed previous algorithms in terms of perceptual quality, color fidelity and execution time. The work presented in this book can find wide application in entertainment industries, transportation, tracking and consumer electronics.

Book Synopsis Combating Mountaintop Removal by : Bryan T. McNeil
Download or read book Combating Mountaintop Removal written by Bryan T. McNeil and published by University of Illinois Press. This book was released on 2011-11-01 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on powerful personal testimonies of the hazards of mountaintop removal in southern West Virginia, Combating Mountaintop Removal critically examines the fierce conflicts over this violent and increasingly prevalent form of strip mining. Bryan T. McNeil documents the changing relationships among the coal industry, communities, environment, and economy from the perspective of local grassroots activist organizations and their broader networks. Focusing on Coal River Mountain Watch (CRMW), an organization composed of individuals who have personal ties to the coal industry in the region, the study reveals a turn away from once-strong traditional labor unions and the emergence of community-based activist organizations. By framing social and moral arguments in terms of the environment, these innovative hybrid movements take advantage of environmentalism's higher profile in contemporary politics. In investigating the local effects of globalization and global economics, McNeil tracks the profound reimagining of social and personal ideas such as identity, history, and landscape and considers their roles in organizing an agenda for progressive community activism.

Book Synopsis There's No Such Thing as Bad Weather by : Linda Åkeson McGurk

Available in PDF, EPUB and Kindle. Book excerpt: Bringing Up Bébé meets Last Child in the Woods in this “fascinating exploration of the importance of the outdoors to childhood development” (Kirkus Reviews) from a Swedish-American mother who sets out to discover if the nature-centric parenting philosophy of her native Scandinavia holds the key to healthier, happier lives for her American children. Could the Scandinavian philosophy of “There’s no such thing as bad weather, only bad clothes” hold the key to happier, healthier lives for American children? When Swedish-born Linda Åkeson McGurk moved to Indiana, she quickly learned that the nature-centric parenting philosophies of her native Scandinavia were not the norm. In Sweden, children play outdoors year-round, regardless of the weather, and letting babies nap outside in freezing temperatures is common and recommended by physicians. Preschoolers spend their days climbing trees, catching frogs, and learning to compost, and environmental education is a key part of the public-school curriculum. In the US, McGurk found the playgrounds deserted, and preschoolers were getting drilled on academics with little time for free play in nature. And when a swimming outing at a nearby creek ended with a fine from a park officer, McGurk realized that the parenting philosophies of her native country and her adopted homeland were worlds apart. Struggling to decide what was best for her family, McGurk embarked on a six-month journey to Sweden with her two daughters to see how their lives would change in a place where spending time in nature is considered essential to a good childhood. Insightful and lively, There’s No Such Thing as Bad Weather is a fascinating personal narrative that illustrates how Scandinavian culture could hold the key to raising healthy, resilient, and confident children in America.

Download or read book First to Fight written by Steven T. Tom and published by Rowman & Littlefield. This book was released on 2019-09-20 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five days after the outbreak of World War I in the summer of 1914, American Kiffin Rockwell was on a ship headed for France. The United States would not join the war for nearly three years, but Rockwell believed it was time to fight. He joined the elite French Foreign Legion and was soon fighting in the trenches of the Western Front. A combat wound in 1915 rendered him unfit to fight on the ground, so Rockwell volunteered to fight in the air, becoming a charter member of the soon-to-be legendary Lafayette Escadrille, a fighter squadron of volunteer American pilots. In May 1916, Rockwell became the first pilot to score a victory for the new unit when he shot down a German plane. He was wounded in the skies over Verdun but refused hospitalization, insisting on remaining in the air. He flew more missions with the Lafayette Escadrille than any other pilot until his death in aerial combat in September 1916. First to Fight is a high-octane drama of a remarkable soldier and pilot who fought in the trenches and in the skies during World War I. It is the story of one of the first American fighter pilots at the dawn of aerial combat, the era of the Red Baron, with dogfighting biplanes high above the trench lines. But more than a World War I story, more than an aviation story, this is the story of an idealist who volunteered—long before his country drafted its first soldier—to fight, and ultimately die, in defense of civilization.

Download or read book The ARVN and the Fight for South Vietnam written by Nghia M. Vo and published by McFarland. This book was released on 2021-08-26 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the withdrawal of French forces from South Vietnam in 1955, the U.S. took an ever-widening role in defending the country against invasion by North Vietnam. By 1965, the U.S. had "Americanized" the war, relegating the Army of the Republic of Vietnam (ARVN) to a supporting role. While the U.S. won many tactical victories, it had difficulty controlling the territory it fought for. As the war grew increasingly unpopular with the American public, the North Vietnamese launched two large-scale invasions in 1968 and 1972--both tactical defeats but strategic victories for the North that precipitated the U.S. policy of "Vietnamization," the drawdown of American forces that left the ARVN to fight alone. This book examines the maturation of the ARVN, and the major battles it fought from 1963 to its demise in 1975. Despite its flaws, the ARVN was a well-organized and disciplined force with an independent spirit and contributed enormously to the war effort. Had the U.S. "Vietnamized" the war earlier, it might have been won in 1967-1968.
