Deconvolution of Images and Spectra , by Peter A. Jansson (Editor)

Hardcover - 514 pages 1st edition January 15, 1997
Academic Press; ISBN: 0123802229

from Book News, Inc.: Provides an overview of the field, along with techniques to successfully apply signal or image processing to corrupt images. The authors assume only a working knowledge of calculus, and emphasize applications over theory, focusing on areas that have been pivotal to the evolution of effective methods. Topics include linear and nonlinear methods of deconvolution, specific applications of a proven method, advances made in restoration of images from cell biology and astronomy, and new methods, including maximum probability estimation, Fourier spectrum continuation, and projections onto convex sets. Each chapter begins with a symbol list, and notation is consistent throughout. -- Copyright © 1999 Book News, Inc., Portland, OR All rights reserved

Reviewer: cameron@rowland.org from Cambridge, MA: "This book is an excellent presentation of exactly what the title says. It starts with a solid mathematical introduction to the topic and then continues with numerous extensions and applications. Recommended if the title interests you."

Seismic Inversion and Deconvolution

Hardcover: 348 pages; (October 1, 1999)
Publisher: Pergamon Press; ISBN: 0080436277

Book Description: The objective of seismic exploration is to delineate the subsurface structure of the earth. A large variety of computer-processing methods are available to transform the observed seismic data into a form that is more useful to the seismic interpreter. An important subdivision of these methods comes under the heading "Seismic Inversion and Deconvolution". Most seismic data are recorded either by geophone that measures particle velocity, or else by hydrophone that measures pressure. A dual sensor incorporates both a geophone and a hydrophone so simultaneous measurements of both particle velocity and pressure are obtained. Unprecedented improvements in inversion and deconvolution are made possible through the use of "Dual-Sensor Technology."

Paperback: 342 pages; January 1995
Publisher: Academic Press; ISBN: 0123802210

Paperback: December 1991
Publisher: Society for Industrial & Applied Mathematics; ISBN: 0898712637

From Book News, Inc.
The content and mode of presentation (conversational) of this basic guide were strongly influenced by the author's experiences at Los Alamos National Laboratory where he found himself explaining the subject to scientists with little mathematical training beyond engineering advanced calculus. Includes problems.

Reviewer: Stephen Fitzpatrick from Stuart, Florida United States
I was a little disappointed by this book. I had expected both descriptions and some practical help with methods to solve (or "resolve", as the author prefers to say) Fredholm integral equations of the first kind (IFK). Instead, the author devotes nearly 100% of his efforts to describing IFK's, why they are difficult to deal with, and why they can't be solved by any "naive" methods. I already knew that IFK's are problematic long before I purchased this book, which is why I bought it! This book is better suited for people who do not yet understand anything about IFK's or why they are difficult to solve. It is most definitely NOT a book that will help you with practical methods/strategies to solve IFK's. If you are looking for help with ways to code a reasonable solution in software (which was my objective), you will definitely need to buy something else.

Article Title: Workingperson's Guide to Deconvolution in Light Microscopy. (See instructions below for link.)

Article Abstract: Workingperson's Guide to Deconvolution in Light Microscopy. The fluorescence microscope is routinely used to study cellular structure in many biomedical research laboratories and is increasingly used as a quantitative assay system for cellular dynamics. One of the major causes of image degradation in the fluorescence microscope is blurring. Deconvolution algorithms use a model of the microscope imaging process to either subtract or reassign out-of-focus blur. A variety of algorithms are now commercially available, each with its own characteristic advantages and disadvantages. In this article, we review the imaging process in the fluorescence microscope and then discuss how the various deconvolution methods work. Finally, we provide a summary of practical tips for using deconvolution and discuss imaging artifacts and how to minimize them.
