Modern Algorithms for Image Processing APress

Książki / Literatura obcojęzyczna

Utilize modern methods for digital image processing and take advantage of the many time-saving templates provided for all of the projects in this book.Modern Algorithms for Image Processing approaches the topic of image processing through teaching by example. Throughout the book, you will create projects that resolve typical problems that you might encounter in the world of digital image processing. Some projects teach you methods for addressing the quality of images, such as reducing random errors or noise and suppressing pulse noise (salt and pepper), a method valuable for improving the quality of historical images. Other methods detail how to correct inhomogeneous illumination, not by means of subtracting the mean illumination, but through division, a far more efficient method. Additional projects cover contrasting, and a process for edge detection, more efficient than Canny's, for detecting edges in color images directly, without converting them into black and white images.What You'll LearnApply innovative methods for suppressing pulse noise, enhancing contrast, and edge detectionKnow the pros and cons of enlisting a particular methodUse new approaches for image compression and recognizing circles in photosUtilize a valuable method for straightening photos of paintings taken at an oblique angle, a critical concept to understand when using flash at a right angleUnderstand the problem statement of polygonal approximation of boundaries or edges and its solutionUse a new method for detecting bicycles in trafficAccess complete source code examples in C# for all of the projects Who This Book Is ForC# developers who work with digital image processing or are interested in informatics. The reader should have programming experience and access to an integrated development environment (IDE), ideally .NET.This book does not prove or disprove theorems, but suggests methods for learning valuable concepts that will enable you to customize your own image processing projects.

Regenerative Garden Cool Springs Press

Książki / Literatura obcojęzyczna

Discover how to work with nature, instead of against it, by employing permaculture techniques to create a garden that is not just more beautiful and productive, but also more resilient.While the word permaculture might sound intimidating, the principals behind it are not. The main goal of permaculture is to turn your space into a functioning ecosystem that's less reliant on external resources and better able to sustain itself through many seasons of growth and change as it resists pests, diseases, and climate extremes. Whatever the size of your space, from a tiny patio garden to a big backyard, and whether you grow food, flowers, shrubs, trees, or a combination of all, The Regenerative Garden is here to help you become a better, more eco-conscious gardener.Through 80 DIY projects, author Stephanie Rose of the popular website Garden Therapy introduces you to basic backyard permaculture concepts in an easy-to-follow, logical way. Each of the six chapters represents a living element of the garden, capable of playing a valuable role in its constant regeneration, including soil, water, plants, climate, ethics, and community. As you check these projects off your to-do list, you'll find you've reduced your long-term work load, conserved water and other resources, turned your yard into a habitat for wildlife, and learned to grow perennial foods in creative ways.The 80 featured projects include step-by-step instructions on how to: Employ intensive planting to reduce weeding and watering choresUse living mulches to amend the soilBuild self-watering planters and wicking beds to reduce water useInstall a rain garden to catch runoffPlant a wildlife hedge to support creatures and create a windbreak and noise bufferCompost projects and systems to repurpose waste on-siteMake a butterfly migration station to support pollinators of all sortsA healthy, organic, regenerative garden is a perfect example of a self-sustaining ecosystem; everything works in tandem, is intricately connected, and comes full circle to create its own never-ending cycle of life.

Lectures on Vibrations Akademia Marynarki Wojennej

MECHANIKA

Owing to their flexibility, the components of structures and machinery are capable of relative motion when subjected to internal or external forces. If such motion is oscillatory in nature, the motion is referred to as vibration. Although applications exist where vibration performs a useful function, vibration in ships is undesirable as it tends to accelerate the wearing of parts such as bearings and gears, create excessive noise and transmit significant forces and/or motion to accommodation, working and recreation spaces as well as to other equipment. Humans may be exposed to vibrations transmitted to the whole body or to particular parts of the body, such as the head or limbs. Designers should primarily be concerned with vibrations transmitted to the body through supporting surfaces such as the buttocks or feet. Research shows that mechanical vibration interferes with work quality and productivity, safety, health, comfort, and causes motion sickness. The literature also shows that vibration may modify crewmember perception (e.g., reading text and instruments, depth perception), influence task control movements (e.g., tactile sense, head/hand movements, manual tracking) and lead to impairment of speech. These factors may result in increased crewmember reaction/response times and possibility of human error. There are many different sources of vibration in ships, such as propeller and stern wake, main engine and other machinery, wave loads and environmental effects. Due to the complexity of these sources of excitation and of the structural configuration of ships, harmful vibration problems still occur even though vibration prediction techniques have developed rapidly and are well established through the use of Finite Element Method software. Continuing research activities have shown that carrying out vibration control is a tend as well as requirement for ships and offshore structures. Also in many other engineering branches it is well known that the proper vibration control in the design process is necessary a safe and satisfactory working and living environment as well as to avoid abnormal wear and tear on the machinery and structures. Since vibration and noise disturb the surrounding medium, their levels should be low also from reason, particularly in submarines. The appropriately reduced acoustic emission and electromagnetic signature of submarines decrease a vessel
