Deconvolution of Images And Spectra

Deconvolution is a technique in signal or image processing that is applied to recover information. When it is employed, it is usually because instrumental effects of spreading and blurring have obscur

fMRI is a very popular method for researchers and clinicians to image human brain activity in response to given mental tasks. This book presents a comprehensive review of the methods for computing activity maps, while providing an intuitive and mathematical outline of how each method works. The approaches include statistical parametric maps (SPM), hemodynamic response modeling and deconvolution, Bayesian, Fourier and nonparametric methods. The newest activity maps provide information on regional connectivity and include principal and independent component analysis, crisp and fuzzy clustering, structural equation modeling, and dynamic causal modeling. Preprocessing and experimental design issues are discussed with references made to the software available for implementing the various methods. Aimed at graduate students and researchers, it will appeal to anyone with an interest in fMRI and who is looking to expand their perspectives of this technique.

UV and X-ray spectroscopy of astrophysical and laboratory plasmas draws interest from many disciplines. Contributions from international specialists are collected together in this book from a timely recent conference. In astrophysics, the Hubble Space Telescope, Astro 1 and ROSAT observatories are now providing UV and X-ray spectra and images of cosmic sources in unprecedented detail, while the Yohkoh mission recently collected superb data on the solar corona. In the laboratory, the development of ion-trap facilities and novel laser experiments are providing vital new data on high temperature plasmas. Recent innovations in the technology of spectroscopic instrumentation are discussed. These papers constitute an excellent up-to-date review of developments in short-wave length spectroscopy and offer a solid introduction to its theoretical and experimental foundations.

The Hubble Space Telescope has made some of the most dramatic discoveries in the history of astronomy. From its vantage point 600km above the Earth, Hubble is able to capture images and spectra that would be difficult or impossible to obtain from the ground. This volume represents some of the most important scientific achievements of the Hubble Space Telescope in its first decade of operation. Written by world experts, the book covers topics ranging from our own solar system to cosmology. Chapters describe cutting edge discoveries in the study of Mars and Jupiter, of stellar birth and death, of star clusters, of the interstellar medium, of our own Milky Way Galaxy and of other galaxies, of supermassive black holes, and of the determination of cosmological parameters, including the age and ultimate fate of our universe. This is an indispensable collection of review articles for researchers and graduate students.

The practical use of space-borne information, its processing and interpretation needs atmospheric correction of aerospace images and spectra. With this book the authors offer a review of this young te

Exploration seismology uses seismic imaging to form detailed images of the Earth's interior, enabling the location of likely petroleum targets. Due to the size of seismic datasets, sophisticated numerical algorithms are required. This book provides a technical guide to the essential algorithms and computational aspects of data processing, covering the theory and methods of seismic imaging. The first part introduces an extensive online library of MATLAB® seismic data processing codes maintained by the CREWES project at the University of Calgary. Later chapters then focus on digital signal theory and relevant aspects of wave propagation and seismic modelling, followed by deconvolution and seismic migration methods. Presenting a rigorous explanation of how to construct seismic images, it provides readers with practical tools and codes to pursue research projects and analyses. It is ideal for advanced students and researchers in applied geophysics, and for practicing exploration geoscienti

The Near Earth Asteroid Rendezvous (NEAR) was the first mission to orbit and eventually land on an asteroid. The mission was a phenomenal success, returning hundreds of thousands of images, spectra, and other measurements about the large near-Earth asteroid 433 Eros. This book is a collection of essays by some of the scientists and engineers who made NEAR such a success. The entire mission is described here in their own words, from the initial concept studies, through the development phase, launch, cruise operations, the flyby of asteroid Mathilde, the near-catastrophic main engine failure in 1998, the heroic rescue and recovery of the spacecraft, the amazing year-long up-close look at one of our most primitive celestial neighbors, and finally the daring attempt to land the spacecraft on Eros at the end of the mission. The book is liberally illustrated throughout with images from the mission and explanatory diagrams.
