Taschenbuch. Condizione: Neu. Neuware - This dissertation demonstrates how the symmetric convolution-multiplication property of discrete trigonometric transforms can be applied to traditional problems in image reconstruction with slightly better performance than Fourier techniques and increased savings in computational complexity for symmetric point spread functions. The fact that the discrete Fourier transform diagonalizes a circulant matrix provides an alternate way to derive the symmetric convolutionmultiplication property for discrete trigonometric transforms. Derived in this manner, the symmetric convolution-multiplication property extends easily to multiple dimensions and generalizes to multidimensional asymmetric sequences. The symmetric convolution-multiplication property allows for linear filtering of degraded images via point-by-point multiplication in the transform domain of trigonometric transforms. Specifically in the transform domain of a type-II discrete cosine transform, there is an asymptotically optimum energy compaction about the lowfrequency indices of highly correlated images which has advantages in reconstructing images with high-frequency noise. The symmetric convolution-multiplication property allows for wellapproximated scalar representations in the trigonometric transform domain for linear reconstruction filters such as the Wiener filter. An analysis of the scalar Wiener filter's improved meansquared error performance in the trigonometric transform domain is given.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Hardcover. Condizione: Fine. No Jacket. lxvii, 760 pages : illustrations ; 29 cm OCLC 52073501 This reprint of the first edition of Sweet's Catalog commemorates the 90th anniversary of the Sweet's business."--Foreword ; "In offering to the public, and especially to the architects of the United States, the first edition of Sweet's Indexed Catalogue of Building Construction, the publishers have realized at the very outset the importance of stating clearly, first, what the book is, and secondly, the reasons for commending it to the architectural profession for their use and support. .to explain in a few words the character and purpose of the work, . a embodied in these first successful efforts toward a really scientific standard catalogue and index of building materials and construction. Let the matter be looked at entirely from the point of view of the architect. For a period of a dozen years, every possible method of collecting, sorting, classifying, filing and indexing all the catalogues and circulars of building materials was conscientiously given a fair trial, and after a thorough test, every method was just as conscientiously abandoned. They were abandoned because they did not work well in the specification room. They were not practicable. Everything was tried, arrangements of shelves, bookcases, pasteboard boxes, filing cases, patent binders, filing cabinets, cases of drawers, indexing schemes and " index- rerums. " At first, all the big books were put together in one place and all the little books in another place; and then all the big and little books were mixed up together, and indexed according to subject. Some had four pages, and some had four hundred pages. Barely two were of the same shape or superficies. The little ones would not stand up, and could not be gotten at when laid flat. Another elaborate system was introduced, and a voluminous cross-index started, but the big books contained too much useless matter, and the little books got lost or mislaid or could not be found just when wanted. Then the writer decided, after much time and expense, that the present system of publishing and distributing catalogues, as far as the architect is concerned, might be rightly termed " The Catalogue Delusion, " and that the only solution of the problem must lie in a scientific standard catalogue and index of building materials and construction, gradually developed toward an ideal result by the co-operation of manufacturer and architect. Briefly, then, what is Sweet's Indexed Catalogue of Building Construction? It is a scientific catalogue book system ( a volume or series of volumes) , as easy to refer to as a dictionary, consisting of groups of catalogues from which as much unnecessary matter as possible has been eliminated, carefully indexed and cross- indexed, and sent out gratuitously by the publishers to every architect of good standing. Each catalogue in the work is organically arranged in its parts. It proceeds in a regular order from fact " A " to fact " Z " . Illustrations of a certain class are all grouped and arranged according to some obvious plan. " Literature " and " mere writing " are omitted, as an architect has no time in his office for either."; authors and compilers include Wm. Martin Aiken, Claire Allen, J. M. Baillie, Charles I. Berg, Otto Block, Claude Bragdon, Arnold W. Brunner, George Cary, Henry M. Congdon, James B. Cook, Francis W. Cooper, R. L. Daus, Robt. E. Dexter, A. F. D'oench, Gustav W. Drach, Wm. S.
