Computational photography refers broadly to imaging techniques that enhance or extend the capabilities of digital photography. This new and rapidly developing research field has evolved from computer vision, image processing, computer graphics and applied optics—and numerous commercial products capitalizing on its principles have already appeared in diverse market applications, due to the gradual migration of computational algorithms from computers to imaging devices and software. Computational Photography: Methods and Applications provides a strong, fundamental understanding of theory and methods, and a foundation upon which to build solutions for many of today's most interesting and challenging computational imaging problems. Elucidating cutting-edge advances and applications in digital imaging, camera image processing, and computational photography, with a focus on related research challenges, this book: Describes single capture image fusion technology for consumer digital cameras Discusses the steps in a camera image processing pipeline, such as visual data compression, color correction and enhancement, denoising, demosaicking, super-resolution reconstruction, deblurring, and high dynamic range imaging Covers shadow detection for surveillance applications, camera-driven document rectification, bilateral filtering and its applications, and painterly rendering of digital images Presents machine-learning methods for automatic image colorization and digital face beautification Explores light field acquisition and processing, space-time light field rendering, and dynamic view synthesis with an array of cameras Because of the urgent challenges associated with emerging digital camera applications, image processing methods for computational photography are of paramount importance to research and development in the imaging community. Presenting the work of leading experts, and edited by a renowned authority in digital color imaging and camera image processing, this book considers the rapid developments in this area and addresses very particular research and application problems. It is ideal as a stand-alone professional reference for design and implementation of digital image and video processing tasks, and it can also be used to support graduate courses in computer vision, digital imaging, visual data processing, and computer graphics, among others.

As the need for geographical data rapidly expands in the 21st century, so too do applications of small-format aerial photography for a wide range of scientific, commercial and governmental purposes. Small-format Aerial Photography (SFAP) presents basic and advanced principles and techniques with an emphasis on digital cameras. Unmanned platforms are described in considerable detail, including kites, helium and hot-air blimps, model airplanes, and paragliders. Several case studies, primarily drawn from the geosciences, are presented to demonstrate how SFAP is actually used in various applications. Many of these integrate SFAP with ground-based investigations as well as conventional large-format aerial photography, satellite imagery, and other kinds of geographic information. Full-color photographs throughout Case studies from around the globe Techniques presented allow for image resolution impossible to match via traditional aerial photography or satellite datasets Glossary clarifies key terms

First developed in the 1880s as a way to monitor glaciers in Europe, repeat photography —the practice of taking photographs at different points in times from the same physical vantage point—remains an essential and cost-effective technique for scientists and researchers working to track and study landscape change. This volume explores the technical and geographic scope of this important technique, focusing particularly on the intertwined influences of climatic variation and land-use practices in sculpting landscapes. Contributors offer a broad-perspective review of the state-of-the-art of repeat photography, with twenty-three chapters written by researchers around the globe who have made use of repeat photography in their work. Topics addressed include the history of repeat photography techniques for creating and analyzing repeat photographs applications in the geosciences applications in population ecology applications in ecosystem change cultural applications Repeat Photography demonstrates the wide range of potential applications, examines new techniques for acquiring data from repeat photography, and clearly shows that repeat photography remains a valuable and efficient means of monitoring change in both developed and developing regions. Over one hundred sets of photographs, including thirty-two pages of color photos, serve as examples. Recent concerns about climate change and its effects on natural landscapes, combined with ongoing concerns about land-use practices, make this state-of-the-art review a timely contribution to the literature.

Excerpt from Photography and Its Applications The object of the author in writing the present book has been not to provide a guide or text book for those desiring to practise the art of photography, but rather to give in a popular manner an outline of its operations for the reader who seeks to know something about photography, without necessarily wanting to practise it. We believe there are many people who like to acquire knowledge of a subject simply for the sake of knowing in a general way "How it's done." It is for such people we have written this book, and we have endeavoured to divest it of detailed technicalities. The task has not been an easy one, and it would have been much less troublesome for the author to proceed on the usual lines of describing the processes with the completeness necessary to enable them to be worked from the instructions given. That would have meant a much larger book, for which probably there is no real need, as there are so many excellent treatises on the subject already published. The author has endeavoured to carry out the aim of the publishers of this series, and if the book should fall into the hands of some who are already well up in the subject, and who may consider there is little that is new in it, let them remember that there are many people who, not having had their advantage, may find such a book as this interesting and possibly useful.
